Lix – universal version control system for binary files

Summary

Changes AI agents make need to be reviewable by humans. For code, Git solves this: Reviewable diffs: What exactly did the agent change? Human-in-the-loop: Review, then merge or reject. Rollback changes: Undo mistakes instantly. But agents modify binary files too. And Git can't diff them. Lix is a universal version control system that can diff any file format (.xlsx, .pdf, .docx, etc). Unlike Git's line-based diffs, Lix understands file structure. Lix sees price: 10 → 12 or cell B4: pending → shipped, not "line 4 changed" or "binary files differ". Reviewable diffs: See exactly what an agent changed in any file format. Human-in-the-loop: Agents propose, humans approve. Safe rollback: Undo mistakes instantly. An AI agent updates an order status in orders.xlsx. Before: | order_id | product | status | | -------- | -------- | -------- | | 1001 | Widget A | shipped | | 1002 | Widget B | pending | After: | order_id | product | status | | -------- | -------- | -------- | | 1001 | Widget A | shipped | | 1002 | Widget B | shipped | Git sees: -Binary files differ Lix sees: order_id 1002 status: - pending + shipped Even for structured text file formats like .json lix is tracking semantics rather than line by line diffs. Before: {"theme":"light","notifications":true,"language":"en"} After: {"theme":"dark","notifications":true,"language":"en"} Git sees: -{"theme":"light","notifications":true,"language":"en"} +{"theme":"dark","notifications":true,"language":"en"} Lix sees: property theme: - light + dark Lix adds a version control system on top of SQL databases that let's you query virtual tables like file, file_history, etc. via plain SQL. These table's are version controlled. Why this matters: Lix doesn't reinvent databases — durability, ACID, and corruption recovery are handled by battle-tested SQL databases. Full SQL support — query your version control system with the same SQL. Can runs in your existing database — no separate storage layer to manage. ┌──────────────────────────...
