Evolu is both a TypeScript library and a local-first platform. Choose your path below.
TypeScript library
For anyone who wants to write TypeScript code that scales. Built on proven design patterns like Result, dependency injection, immutability, and more. Created by someone who spent years with functional programming, but then decided to go back to the simple and idiomatic TypeScript code—no pipes, no black-box abstractions, no unreadable stacktraces.

Local-first platform
A complete platform for building apps where users own their data. Works offline-first with sync via self-hostable or cloud relays. End-to-end encrypted by default. Built on SQLite with a scalable sync protocol designed for real-world use. No vendor lock-in, no data hostage situations.
