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.

Semifold was inspired by the great work from the following projects:
Changesets — a simple and elegant changeset-based versioning workflow, mainly focused on JavaScript and npm monorepos.
Covector — a flexible multi-target release manager designed to support more complex ecosystems.
