Discover the whole repository
Turn Cargo, npm, Python, C++, and plugin-defined packages into one dependency-aware workspace.
Versioning and releases across languages and ecosystems
One repository. Many ecosystems. One release workflow.
Semifold connects package discovery, changesets, version propagation, changelogs, and dependency-ordered publishing across every language in your repository.

01 / ONE REPOSITORY
Treat the repository as one product system
Each ecosystem keeps its own manifest and registry rules. Semifold handles the relationships between them.
Version related packages together
Record a change once, then update affected versions, internal requirements, and changelogs consistently.
Publish in dependency order
Use the right command and registry checks for each ecosystem while keeping one recoverable release run.
02 / ECOSYSTEMS & PLUGINS
Built in for common ecosystems. Extensible for yours.
Use the maintained adapters for familiar package formats, or add a repository-local JavaScript plugin without giving it unrestricted access to your machine.

Node.js
