75+ Free Developer Tools & Resources | Curated for 2026

GTmetrix

Analyze page speed, find bottlenecks, and optimize your site for Core Web Vitals with waterfall charts and detailed performance reports.

Praktijknotitie

The waterfall view is the quickest way to spot which third-party script is actually blocking render. The free tier limits test locations, so pair it with WebPageTest when geography matters.

Prestaties Keuze

Google PageSpeed Insights

Get real-world performance data from Chrome UX Report with actionable optimization suggestions powered by Lighthouse.

Praktijknotitie

The score that maps to what Google actually measures, because it pulls real Chrome field data. Treat the lab number as a hint and chase the field Core Web Vitals — those are what rank.

Tool Bezoeken pagespeed.web.dev

Prestaties

Lighthouse

Run automated audits for performance, accessibility, SEO, and best practices directly in Chrome DevTools or CI pipelines.

Praktijknotitie

Same engine as PageSpeed but scriptable — wire it into CI so a perf regression fails the build instead of surfacing in production. The accessibility audit alone catches issues most teams ship.

Tool Bezoeken developer.chrome.com

Prestaties

WebPageTest

Advanced performance testing from 40+ global locations with filmstrip view, video comparison, and Core Web Vitals breakdown.

Praktijknotitie

When a client says "it's slow in Europe," this is how you prove it — test from the real region and watch the filmstrip. Its connection-throttling presets are more honest than a fast office network.

Tool Bezoeken www.webpagetest.org

Prestaties

TinyPNG

Compress PNG and JPEG images by up to 70% without visible quality loss using smart lossy compression algorithms.

Praktijknotitie

The fastest option for squashing a one-off image before committing it. For a build pipeline, reach for Squoosh's CLI instead — but for dragging a hero image down 60% in seconds, nothing beats it.

Tool Bezoeken tinypng.com

Prestaties

Bundlephobia

Check the size cost of adding any npm package to your JavaScript bundle before installing it in your project.

Praktijknotitie

Check this before npm install, not after. Watching a "small" date library add 70KB gzipped to your bundle is the cheapest performance lesson you will get.

Tool Bezoeken bundlephobia.com

Prestaties

Squoosh

Advanced image compression app by Google Chrome Labs supporting WebP, AVIF, and MozJPEG with visual comparison.

Praktijknotitie

Worth it for the side-by-side slider alone — push AVIF until the artifacts show, then back off a notch. The local CLI version is the one to script into an asset build.

Tool Bezoeken squoosh.app

Beveiliging Prestaties Keuze

Cloudflare

Protect and accelerate your website with CDN, DDoS protection, Web Application Firewall, DNS management, and zero-trust security.

Praktijknotitie

The free tier does more than most paid WAFs — DNS, caching, and DDoS absorption out of the box. The catch: aggressive caching can hide a deploy, so learn the purge and dev-mode toggles early.

Tool Bezoeken www.cloudflare.com

Beveiliging Keuze

SSL Labs

Deep analysis of your SSL/TLS server configuration with detailed grading, certificate chain validation, and protocol testing.

Praktijknotitie

Run it after every TLS change. An A+ is not vanity — a B usually means an old protocol or weak cipher is still enabled, and the report points at the exact config line to fix.

Tool Bezoeken www.ssllabs.com

Beveiliging

Security Headers

Scan your website's HTTP security headers and get an instant grade with actionable recommendations for each missing header.

Praktijknotitie

A 30-second grade that catches the headers everyone forgets — CSP, HSTS, frame options. It only inspects response headers, so it won't find app-layer bugs, but it flags the cheap wins first.

Tool Bezoeken securityheaders.com

Beveiliging

Mozilla Observatory

Comprehensive security assessment covering HTTP headers, TLS configuration, cookies, and third-party content best practices.

Praktijknotitie

Goes a step past a headers grade by checking cookie flags and subresource integrity. Worth running alongside Security Headers — the two disagree just often enough to be a useful cross-check.

Tool Bezoeken observatory.mozilla.org

Beveiliging

Have I Been Pwned

Check if your email or phone number has been compromised in any data breach across 700+ breached sites and 14B+ accounts.

Praktijknotitie

The real power is the API — wire it into signup to reject known-breached passwords before they are ever set. As a personal check, set the breach alerts once and forget it until one finds you.

Tool Bezoeken haveibeenpwned.com

OWASP ZAP

Open-source web application security scanner for finding vulnerabilities like XSS, SQL injection, and CSRF during development.

Praktijknotitie

The free Burp Suite alternative for teams without the license budget. The automated scan finds the obvious XSS and injection; the manual proxy is where the real testing starts once you learn it.

Tool Bezoeken www.zaproxy.org

Beveiliging

CSP Evaluator

Evaluate and validate your Content Security Policy for weaknesses, bypasses, and misconfigurations using Google's analysis engine.

Praktijknotitie

Hand-writing a CSP is how you accidentally allow unsafe-inline and undo the whole point. Paste your policy here first — it flags the bypasses Google's own researchers know about.

Tool Bezoeken csp-evaluator.withgoogle.com

Beveiliging Leren

Web Security Academy

Learn real-world web security with free interactive labs covering OWASP Top 10, API security, and advanced topics from PortSwigger.

Praktijknotitie

Free, and better than most paid courses — the labs are real exploitable targets, not multiple-choice quizzes. Do just the SQL injection and XSS tracks and you'll out-skill most developers on security.

Tool Bezoeken portswigger.net

Ontwikkeling Keuze

Visual Studio Code

Free, extensible code editor with IntelliSense, integrated debugging, Git support, and 40,000+ extensions for every language.

Praktijknotitie

The default for good reason, but the win is restraint — ten well-chosen extensions beat fifty that fight each other. Learn the multi-cursor and command-palette muscle memory and the mouse goes quiet.

Tool Bezoeken code.visualstudio.com

Ontwikkeling AI & ML Keuze

Cursor

AI-first code editor built on VS Code with native AI integration for intelligent code generation, editing, and codebase understanding.

Praktijknotitie

It is VS Code with the AI in the editing loop, so your existing setup carries over. Composer mode earns its keep on multi-file refactors; for single-line completions the gap from Copilot is marginal.

Tool Bezoeken www.cursor.com

Ontwikkeling Keuze

GitHub

Host repositories, automate CI/CD, manage issues, and collaborate with 100M+ developers — version control plus Actions, Copilot, and project boards in one place.

Praktijknotitie

The hosting is table stakes now — the reason to centralize here is Actions and the ecosystem around it. For private solo work, the free tier is more generous than people assume.

Tool Bezoeken github.com

Ontwikkeling

Postman

Design, test, and document APIs with a collaborative platform supporting REST, GraphQL, WebSocket, and gRPC protocols.

Praktijknotitie

Strongest for sharing a documented API collection with a team or client. For quick solo checks, Hoppscotch is lighter — the account-gating and bloat here are the price of the collaboration features.

Tool Bezoeken www.postman.com

Ontwikkeling

Hoppscotch

Open-source, lightweight API testing tool for REST, GraphQL, and WebSocket APIs directly in your browser with zero setup.

Praktijknotitie

The tab to open when you just need to fire a request without signing into anything. Runs in the browser and remembers nothing you don't ask it to — what Postman was before it grew an account wall.

Tool Bezoeken hoppscotch.io

Ontwikkeling

Regex101

Build, test, and debug regular expressions with real-time explanations, match highlighting, and a library of community patterns.

Praktijknotitie

The explanation pane is the actual product — it turns a write-only regex into something you can hand to a teammate. Set the flavor to match your language or you'll ship a pattern that works everywhere but prod.

Tool Bezoeken regex101.com

Ontwikkeling

Carbon

Create beautiful screenshots of your code for sharing on social media, documentation, slides, or blog posts with custom themes.

Praktijknotitie

For the code screenshots in slide decks and posts. Keep it for presentation only — never share an image of code people actually need to copy; that is what a gist is for.

Tool Bezoeken carbon.now.sh

Ontwikkeling

DevDocs

Fast, offline-capable API documentation browser combining 600+ docs in a clean, searchable interface with instant results.

Praktijknotitie

Install it as an offline app and search across every framework's docs in one keystroke. On a flaky connection or a flight, having the full API reference cached locally pays for itself fast.

Tool Bezoeken devdocs.io

Ontwikkeling

JSON Crack

Visualize JSON, YAML, and CSV data as interactive graphs to understand complex nested structures and relationships at a glance.

Praktijknotitie

Drop a gnarly nested API response in and the node graph makes the shape obvious in a way raw text never will. Mind that pasting sensitive payloads sends them to a third party — sanitize first.

Tool Bezoeken jsoncrack.com

AI & ML Keuze

Hugging Face

Find, fine-tune, and deploy machine-learning models from a hub of 500K+ pretrained models, datasets, and hosted Spaces — the package registry of ML.

Praktijknotitie

Start from a model card, not a tutorial — the good ones document the training data and the failure modes. Spaces is the fastest way to demo a model without provisioning a single GPU.

Tool Bezoeken huggingface.co

AI & ML Keuze

ChatGPT

OpenAI's conversational AI for coding assistance, content generation, data analysis, and creative problem-solving with GPT-4.

Praktijknotitie

Strongest as a thinking partner for brainstorming and first drafts. For heavy coding I lean on Claude, but the broader plugin and image ecosystem still wins for mixed tasks — keep one of each open.

Tool Bezoeken chat.openai.com

AI & ML Keuze

Claude

Anthropic's AI assistant excelling at analysis, coding, math, and long-context conversations with industry-leading safety standards.

Praktijknotitie

My default for anything involving large codebases or long documents — the context window and a willingness to say "this won't work" make it the better pair-programmer. This site's content workflows run on it.

Tool Bezoeken claude.ai

AI & ML

Google Colab

Free Jupyter notebook environment with GPU and TPU access for machine learning experiments, data analysis, and education.

Praktijknotitie

Free GPU with zero local setup — perfect for a notebook you'll run a handful of times. The session timeouts and disconnects make it the wrong tool for anything that needs to train overnight.

Tool Bezoeken colab.research.google.com

AI & ML

Kaggle

Machine learning competition platform with 200K+ free datasets, GPU-powered notebooks, courses, and a vibrant data science community.

Praktijknotitie

The datasets and public notebooks teach a technique faster than any course — you read how people actually solved the problem. The competitions drive home that real ML is mostly feature engineering.

Tool Bezoeken www.kaggle.com

AI & ML

Ollama

Run large language models locally on your machine with a simple CLI — supports Llama 3, Mistral, Gemma, CodeLlama, and 100+ models.

Praktijknotitie

The cleanest way to run a local model — ollama run llama3 and you're talking to it. Great for privacy-sensitive prototyping; just be realistic that consumer hardware caps you below frontier quality.

Tool Bezoeken ollama.com

AI & ML

Replicate

Run and deploy open-source ML models in the cloud with simple API calls, auto-scaling, and pay-per-second pricing.

Praktijknotitie

When you want to call an open-source model by API without owning the GPU — pay per second, scales to zero. The cost math flips once usage is steady, at which point self-hosting starts to win.

Tool Bezoeken replicate.com

AI & ML

Gradio

Build and share machine learning demos and web applications with a few lines of Python — deploy to Hugging Face Spaces instantly.

Praktijknotitie

The fastest path from a Python function to a shareable demo URL — good for putting a model in front of a non-technical stakeholder in an afternoon. Pairs naturally with Hugging Face Spaces for free hosting.

Tool Bezoeken www.gradio.app

AI & ML

LM Studio

Desktop app to discover, download, and run local LLMs with a chat interface and an OpenAI-compatible local API server.

Praktijknotitie

The friendlier face on local LLMs if you'd rather click than type — and the built-in OpenAI-compatible server is the quiet killer feature for swapping a cloud API for a local one in your own app.

Tool Bezoeken lmstudio.ai

v0 by Vercel

AI-powered UI generation tool that creates production-ready React components from text descriptions using shadcn/ui and Tailwind.

Praktijknotitie

Good for a first-pass UI scaffold when you're staring at a blank component. Treat the output as a sketch, not shippable code — it leans on shadcn/Tailwind conventions you'll still need to clean up.

Tool Bezoeken v0.dev

Monitoring Keuze

UptimeRobot

Monitor website uptime every 5 minutes with 50 free monitors and instant alerts via email, SMS, Slack, or webhooks.

Praktijknotitie

Fifty free monitors covers a whole portfolio of sites. The 5-minute interval means you hear about an outage a few minutes late — fine for marketing sites, not for anything with a real SLA.

Tool Bezoeken uptimerobot.com

Monitoring Keuze

Google Analytics

Industry-standard web analytics for tracking traffic sources, user behavior, conversions, and audience demographics at any scale.

Praktijknotitie

Still the default, but GA4 buries the answers — set up the explorations you actually need once and bookmark them. If you only care about traffic sources, Plausible is far less pain.

Tool Bezoeken analytics.google.com

Monitoring

Sentry

Application monitoring and error tracking for frontend, backend, and mobile with detailed stack traces, breadcrumbs, and session replay.

Praktijknotitie

The first thing to add to a new production app — a stack trace with breadcrumbs beats a user's vague bug report every time. Watch the event quota; a noisy error in a loop burns the free tier in an hour.

Tool Bezoeken sentry.io

Monitoring

Plausible Analytics

Lightweight, privacy-friendly web analytics that is GDPR/CCPA compliant, cookie-free, and under 1KB in script size.

Praktijknotitie

What to reach for when you want honest traffic numbers with no cookie banner — under 1KB and the whole dashboard fits on one screen. The trade-off is no deep funnel analysis, which is rather the point.

Tool Bezoeken plausible.io

Monitoring

Better Stack

Beautiful uptime monitoring, incident management, and log aggregation in a developer-friendly platform with Slack and PagerDuty integrations.

Praktijknotitie

Uptime monitoring with status pages and on-call that actually looks good — the polish you'd otherwise pay an enterprise vendor for. The free tier covers a small project comfortably.

Tool Bezoeken betterstack.com

Monitoring

Checkly

Monitor API endpoints and browser interactions with programmable synthetic checks using Playwright and Node.js from 20+ global locations.

Praktijknotitie

Where it pulls ahead is monitoring user journeys, not just pings — write a Playwright script and it runs the real login flow on a schedule. The right call when "the homepage is up" isn't "checkout works."

Tool Bezoeken www.checklyhq.com

Design & UI Keuze

Figma

Collaborative interface design tool for UI/UX with prototyping, design systems, Dev Mode, and real-time multiplayer editing.

Praktijknotitie

The one design tool worth standardizing on — and as a developer, Dev Mode is the part that matters: real measurements, exportable assets, inspectable tokens. You don't need to design to read a file in it.

Tool Bezoeken www.figma.com

Design & UI Ontwikkeling Keuze

Tailwind CSS

Utility-first CSS framework for rapidly building modern UIs with a rich plugin ecosystem, JIT compiler, and excellent DX.

Praktijknotitie

It feels wrong until it clicks, then you don't go back — the constraint of a utility scale is what keeps spacing consistent across a project. The catch is class soup; extract components before the markup rots.

Tool Bezoeken tailwindcss.com

Design & UI

Heroicons

Hand-crafted SVG icons by the Tailwind CSS team — 300+ glyphs available as React and Vue components or raw SVGs.

Praktijknotitie

Made by the Tailwind team, so they drop into a Tailwind project without a fight. The set is small by design — when 300 icons isn't enough, Lucide picks up where it stops.

Tool Bezoeken heroicons.com

Design & UI

Coolors

Generate perfect color palettes in seconds with contrast checking, palette exploration, color blindness simulation, and export to any format.

Praktijknotitie

The spacebar-to-generate flow is the fastest way out of palette paralysis. Lock the one color you're sure of and cycle the rest — then always run the result through its contrast checker before committing.

Tool Bezoeken coolors.co

Design & UI

Unsplash

Access 4M+ free high-resolution photos from 300K+ photographers for commercial and personal use — no attribution required.

Praktijknotitie

Free, genuinely high quality, no attribution required — but that's also the catch: the popular shots are everywhere, so dig past page one or your site looks like every other startup's.

Tool Bezoeken unsplash.com

Design & UI

Excalidraw

Virtual whiteboard for sketching diagrams with a hand-drawn aesthetic, real-time collaboration, and easy embedding in docs.

Praktijknotitie

The default for any diagram that should feel like a sketch, not a spec — the hand-drawn look invites edits a polished chart doesn't. Perfect for whiteboarding an architecture before it's real.

Tool Bezoeken excalidraw.com

Design & UI

Lucide Icons

Consistent open-source icon library with 1,500+ icons available as SVG, React, Vue, Svelte, and more.

Praktijknotitie

The community fork of Feather, grown to 1,500+ icons with consistent stroke weights — the pick when you need breadth and a framework-native component. Where Heroicons runs out, this keeps going.

Tool Bezoeken lucide.dev

Realtime Colors

Visualize your color palette on a real website mockup instantly — see how your font, background, and accent choices feel in context.

Praktijknotitie

Solves the real problem: a palette looks fine on swatches and falls apart on an actual page. Preview your colors on a real mockup here before you wire them into design tokens.

SEO & Marketing Keuze

Google Search Console

Monitor your site's search performance, fix indexing issues, submit sitemaps, and understand how Google discovers your pages.

Ahrefs Webmaster Tools

Free site audit scanning 100+ SEO issues, backlink profile analysis, and organic keyword tracking for website owners.

Screaming Frog SEO Spider

Desktop SEO crawler for auditing technical SEO — find broken links, analyze metadata, audit redirects, and generate XML sitemaps.

Praktijknotitie

The crawler to run before and after any big site change — it finds the broken links, redirect chains, and orphan pages no dashboard surfaces. Free up to 500 URLs, which covers most personal sites whole.

Tool Bezoeken www.screamingfrog.co.uk

Schema Markup Validator

Test and validate your structured data markup to ensure rich result eligibility and correct implementation in Google Search.

Praktijknotitie

Run your structured data through this before you trust it — one malformed field silently kills rich-result eligibility. Keep it bookmarked next to Google's Rich Results Test and check both.

AnswerThePublic

Discover what questions real people ask about any topic — fuel your content strategy with search-driven keyword and question research.

The fastest way to turn one keyword into a content outline — the question wheel is real searcher language, not your guess at it. The free daily limit is tight, so batch your queries.

Tool Bezoeken answerthepublic.com

Google Trends

Explore trending search queries, compare keyword popularity over time, and discover seasonal patterns across regions and categories.

Praktijknotitie

Best for one decision: is interest in this topic rising or dying? Use it to time content and to settle "which term do people actually search" debates with the comparison view.

Tool Bezoeken trends.google.com

SEO & Marketing

Ubersuggest

Keyword research tool with search volume, SEO difficulty scores, content ideas, backlink data, and competitor domain analysis.

Praktijknotitie

A reasonable free-tier entry point for volume and difficulty if Ahrefs and Semrush are out of budget. Treat the metrics as directional, not gospel — they're estimates, and the upsells are persistent.

Tool Bezoeken neilpatel.com

DevOps & Cloud Keuze

Docker

Build, ship, and run applications in containers for consistent development, testing, and production environments everywhere.

Praktijknotitie

The thing that ended "works on my machine" — learn it even if you deploy elsewhere, because everything downstream assumes it. Keep images slim; a multi-stage build is 1GB versus 80MB.

Tool Bezoeken www.docker.com

DevOps & Cloud Keuze

Vercel

Deploy frontend applications with zero configuration, edge functions, automatic HTTPS, preview deployments, and global CDN.

Praktijknotitie

The shortest path from a Git push to a live URL for anything frontend — per-branch preview deploys are the feature you miss everywhere else. Watch the bandwidth and function pricing once a project gets traffic.

Tool Bezoeken vercel.com

DevOps & Cloud

GitHub Actions

Automate CI/CD workflows, testing, linting, and deployment directly from your GitHub repository with 15,000+ community actions.

Praktijknotitie

CI/CD that lives next to your code with no extra service to wire up — this site deploys through it. The marketplace saves writing YAML from scratch, but pin action versions or a supply-chain surprise awaits.

Tool Bezoeken github.com

DevOps & Cloud

DigitalOcean

Simple, affordable cloud infrastructure with droplets, managed databases, Kubernetes, serverless functions, and app platform.

Praktijknotitie

The cloud to recommend to anyone overwhelmed by AWS's console — predictable pricing and docs you can actually follow. You give up the deep managed-service catalog, which most projects never needed.

Tool Bezoeken www.digitalocean.com

DevOps & Cloud

Coolify

Self-hostable, open-source alternative to Heroku and Netlify with Docker-based deployments, databases, and SSL on your own server.

Praktijknotitie

Self-hosted Heroku — point it at a VPS and get Git-push deploys, databases, and SSL without the per-seat bill. The trade: you're now on call for the server. Worth it once you've outgrown free tiers.

Tool Bezoeken coolify.io

DevOps & Cloud

Railway

Deploy applications, databases, and services instantly with automatic builds from Git, horizontal scaling, and a generous free tier.

Praktijknotitie

The nicest developer experience for spinning up an app plus its database in minutes — great for prototypes. The usage-based pricing is fair but climbs, so watch it before it quietly becomes your main host.

Tool Bezoeken railway.app

Laravel Forge

Provision and manage optimized PHP servers on AWS, DigitalOcean, or any VPS with automated deployments, SSL, and queue workers.

Praktijknotitie

If you ship Laravel, this removes the server-config tax — provisioning, deploys, queue workers, and SSL handled. It manages servers on your own cloud account, so you keep the infrastructure without the grind.

Notion

All-in-one workspace combining notes, docs, wikis, project boards, databases, and AI writing in a flexible, block-based interface.

Praktijknotitie

Run docs, planning, and a lightweight CRM in one workspace — the database-as-a-page model is what makes it flex. The cost is that it happily becomes a mess; impose structure early or search becomes your only nav.

Linear

Streamlined issue tracking and project management for high-performance teams with keyboard-first design and GitHub integration.

Raycast

Blazingly fast Mac launcher replacing Spotlight with extensions for GitHub, Jira, Figma, clipboard history, and custom scripts.

Praktijknotitie

Replaces Spotlight on day one and a dozen other apps within a week — clipboard history and window management alone justify it. The extension store is where it stops being a launcher and becomes a workflow.

Obsidian

Private knowledge base using local Markdown files with bidirectional linking, graph visualization, and 1,000+ community plugins.

Praktijknotitie

Notes as plain Markdown files you own, on disk, forever — that's the whole pitch and it's the right one. The graph view is mostly eye candy; the backlinks are what change how you write. Sync is the paid catch.

Tool Bezoeken obsidian.md

Productiviteit

Cal.com

Open-source scheduling platform for booking meetings with calendar sync, custom availability rules, team scheduling, and API access.

Praktijknotitie

The open-source Calendly — self-host it and stop renting your own scheduling page. The hosted tier is fine too; the reason to pick it over the incumbent is owning the data and the booking flow end to end.

Tool Bezoeken cal.com

Productiviteit

Warp

Modern terminal reimagined with AI command search, collaborative workflows, IDE-like editing, and intelligent auto-completions.

Loom

Record and share quick video messages for async communication with automatic transcription, viewer insights, and team libraries.

Laracasts

Premier video tutorial platform for Laravel, PHP, Vue.js, and modern web development with expert instruction and hands-on exercises.

freeCodeCamp

Free, interactive coding curriculum with 12 certifications covering web development, data science, machine learning, and more.

Inclusive developer community for sharing articles, tutorials, and discussions about programming, career growth, and technology.
