Open source · MIT · zero-dependency tool cores
Free tools, made with zeal.
No sign-ups, no watermarks, no nonsense. Every tool usable three ways: UI · REST API · MCP.
All tools
The Zeal Promise
Non-negotiable, on every tool we ship.
- No sign-up — ever
- No watermarks on any output
- No ads near the download button
- Works fully on mobile
- Privacy-first: processing stays in your browser
- Open source (MIT) — audit it, contribute, self-host
- Zero runtime dependencies in tool logic
Free REST API — no keys
Every tool is a pure function, so every tool is an endpoint. No API key, no sign-up.
