Built for developers,
by developers
MicroTools is a collection of free, open utilities designed to remove friction from your daily development workflow. Every tool runs 100% in your browser — your data never leaves your device.
Why MicroTools?
We got tired of bloated, ad-filled, login-required tools that slow you down and share your data with third parties. MicroTools was built to be the opposite: instant, private, and always free.
Every tool is a focused micro-utility — no feature bloat, no dark patterns. Just open it, use it, done.
100% Private by Design
All processing happens client-side in your browser using JavaScript. We have zero access to the data you enter into any tool. No pastes are stored, no logs are kept, no analytics are tied to your usage.
You can even use most tools offline after the initial page load.
30+ Tools and Growing
Phase 1 covers the essentials: JSON/YAML/XML formatters, JWT tools, Base64 & URL encoders, regex testers, hash generators, CSV converters, and much more.
Phase 2 will introduce AI-assisted tools, team features, and API integrations — all with the same privacy-first approach.
Free. Forever.
Core tools will always be free. We plan to offer premium features for teams and power users in the future, but the essentials will never go behind a paywall.
No ads, no tracking pixels, no data sold to third parties. That's our promise.
