Lix is a universal version control system for any file format. Unlike Git's line-based diffs, Lix understands file structure, showing 'price: 10 → 12' instead of 'line 4 changed'.

Lix is a universal version control system that can diff any file format, including binary files like Excel, PDF, and DOCX. Unlike Git's line-based diffs, Lix understands file structure and shows semantic changes (e.g., 'price: 10 → 12' instead of 'line 4 changed'). Built on top of SQL databases, it provides version control through virtual tables queryable via SQL. Originally developed for inlang localization infrastructure, Lix addresses Git's limitations with binary and structured files, making it particularly useful for AI agent workflows where changes to non-text files need human review. Currently available for JavaScript with Python, Rust, and Go SDKs planned.

Introducing Lix: A universal version control system

AI agents need version control beyond text

I like the idea of using database as a file format and semantic change provided by plugins.

This is a fantastic concept… JS? seriously? that was the first plan? when i read the title i thought… ok, what is this going to solve, clear, cleanly articulated just in the synapse, so it’s piqued my interest, having built SaaS platform for law work which is HEAVY on the binary diff needs this is something I might be able to get behind for a platform integration … 👀 for extended SDK’s as JS is not a goto language for me doing heavy backend work and needs I was quite shocked to see JS as the primary language of choice for this genre of toolset;

I like the idea of having version control for binary files like documents and powerpoints, fascinating!
