Semifold

Next-generation cross-language monorepo version and release management tool.

Nowadays, cross-language monorepos are becoming more and more common. For example, a monorepo may contain a Rust library and a Node.js package, developers use napi-rs to create Rust bindings for Node.js.

semifold (CLI: smif | semifold) helps teams manage versions, changelogs, and package publishing across large cross-language monorepos with consistency, automation, and zero pain. Whether you are building libraries, apps, or services across multiple languages, Semifold keeps your release pipeline clean and predictable.
