About Toolhaus
Toolhaus is a developer utility tools hub—a single branded destination hosting 25+ small, fast, privacy-first tools that developers use daily. Every tool runs entirely client-side; no server ever sees your data.
We believe developer tools should respect your privacy. That's why all processing happens in your browser. Share results via URL—no sign-in required for free tools.
Toolhaus is monetised via EthicalAds for free users and a Pro subscription that removes ads and unlocks power features like tool history and larger file limits.
Tech stack
Built with Next.js 15, React 19, TypeScript, Tailwind CSS v4, and shadcn/ui. Tools run in the browser using Web Crypto, CodeMirror, and other client-side libraries. No backend processing for tool logic.
Open source
Our codebase is available on GitHub for verification. You can inspect how we handle your data—or lack thereof.
