firelock-ai/kin

Overview

An open-source repository and version control system built in Rust that treats functions, types, recorded relationships and change history as first-class repository data. Developers commit, branch and merge these code artifacts, and can look up what a change might affect before making it. Currently in public alpha.

Best for

• Branch and merge semantic code artifacts alongside source history
• Audit recorded relationships and change history for AI agent workflows

How to use

Install

Use cases

• Trace which functions or types depend on a code change before merging
• Branch and merge semantic code artifacts alongside source history
• Audit recorded relationships and change history for AI agent workflows

Pros

• Makes code structure and dependencies versionable data
• Enables impact analysis directly from repository queries
• Open source with a Rust implementation

Cons

• Public alpha, so stability and APIs may change
• Small community with limited adoption (61 stars)
• Paradigm differs from traditional VCS, so migration requires new workflows
