About Utilito

Utilito is a collection of fast, free utility tools for developers, builders, and AI agents.

Why it exists

Most small developer tasks should not require a signup, a bloated app, or a server round trip. Utilito gives you simple tools that work quickly in the browser: format JSON, convert colors, generate UUIDs, decode JWTs, test regex, and more.

The same deterministic tools are also exposed through an API and MCP server so AI agents can call exact utilities instead of spending tokens guessing, formatting, hashing, or transforming data manually.
