General
What is MicroTools?
MicroTools is a free collection of developer utilities — JSON formatters, hash generators, JWT tools, converters, and more. Every tool runs entirely in your browser with no server-side processing.
Do I need to create an account?
No. All tools are freely accessible without any sign-up, login, or email required. Just open the tool and use it.
Is MicroTools really free?
Yes. Core tools are free and will remain free forever. We may introduce optional premium features in the future for teams and power users, but the essentials will never be paywalled.
Does MicroTools work offline?
After your first visit, most tools will work offline since all the logic runs in your browser. No network requests are made when you use a tool.
Privacy & Security
Do you store the data I paste into tools?
No. All processing happens locally in your browser. We have zero visibility into what you type, paste, or generate. Nothing is sent to our servers.
Is it safe to paste sensitive data like JWT tokens or passwords?
Yes. Since everything runs client-side, your data never leaves your browser. That said, always exercise caution with production secrets — use test or dummy values whenever possible.
Do you use cookies or tracking?
We use localStorage only to save your theme preference (light/dark). We do not use advertising cookies, third-party trackers, or fingerprinting technologies.
What analytics do you collect?
We may collect minimal, anonymized page-view analytics to understand which tools are popular. No personally identifiable information is collected. See our Privacy Policy for full details.
Tools
How many tools are available?
Phase 1 includes 30 tools covering formatters, encoders, generators, converters, validators, and utilities. More tools are added regularly.
Can I request a new tool?
Absolutely. Use our Contact page to submit a tool request. We prioritize tools that developers commonly need and that can be implemented client-side.
What are the AI tools and how do they work?
Tools labeled "AI" (like AI Regex Generator and AI JSON Fixer) currently use smart pattern-matching heuristics. In Phase 2, they will be connected to an AI backend to handle more complex cases — the badge will note when full AI is live.
Why do some tools show a "Pro" badge?
The "Pro" badge marks tools that will gain enhanced AI capabilities in Phase 2. They are fully functional now with our built-in heuristics — the Pro tier will unlock richer AI-powered features.
Technical
What technologies does MicroTools use?
MicroTools is built with Astro (static site generator), React for interactive tool components, and Tailwind CSS v4. It is deployed as a static site on Cloudflare Pages.
Is MicroTools open source?
The core tool implementations are designed to be transparent and inspectable. Open source plans are being finalized.
Can I embed a MicroTools tool in my own site?
Currently we do not offer an embed API. This is on our roadmap. Sign up for updates or reach out via the Contact page to express interest.
