Universal version control system

Lix is a version control system for any file format: code, documents, spreadsheets, design files, video, datasets. It runs in-process on pluggable storage. Files, app tables, and history are rows in one ACID database. Agents read and write normal files. Your product queries SQL. You branch, diff, merge, and roll back all of it together:

Any format. Text, binaries, large blobs. Plugins make formats like DOCX, XLSX, and JSON diffable and mergeable by clause, cell, or row.
Embeddable. Runs in-process as a library. Storage is pluggable: memory, filesystem, browser OPFS, or S3.
️ Designed as a database. File content, app tables, and history are rows in one ACID OLTP database. Query millions of rows with SQL.
⚡ Real-time collaboration. People and agents share a repository and see changes as they happen.
Permissions (planned). Per file, per group, stored in the repository and versioned like any other change.

Why not Git?

Git is a CLI designed for source code. It assumes a local POSIX filesystem, tracks whole files, and diffs text lines. Keep software engineering in Git. Use Lix when your product stores files and data for its users.

	Git	Lix
Process model	Separate CLI process	Library in your process
Storage	Local disk	Memory · filesystem · OPFS · S3
Application data	Separate database	SQL rows, ACID, with the files
Recording changes	Manual commits	Every write, automatically
Formats	Text lines	Any, by clause, cell, or row
Collaboration	Push and pull	Real time

Getting started

JavaScript · Rust · Python · Go

bash

npm install @lix-js/sdk @lix-js/storage-filesystem

Run locally with FilesystemStorage:

typescript

import { openLix } from "@lix-js/sdk";
import { FilesystemStorage } from "@lix-js/storage-filesystem";

const lix = await openLix({
  storage: new FilesystemStorage({ path: "./repository" }),
});

await lix.execute("INSERT INTO lix_file (path, content) VALUES ($1, $2)", [
  "/notes/status.txt",
  new TextEncoder().encode("ready"),
]);

Or against a server:

typescript

const lix = await openLix({
  server: {
    url: "https://example.com/lix/01936f4e-7b6c-7c3d-8f9a-123456789abc",
  },
});

Lix is in alpha.

Prime use cases

Co-locate code, documents, and app state

Code lives in Git. Documents, design files, and media live in Drive, Figma, and S3. App state lives in Postgres. No system versions all of them together. Lix stores them in one repository with one history.

typescript

// A script, a 4.8 GB video, and an app table in one transaction.
await lix.executeBatch([
  {
    sql: "INSERT INTO lix_file (path, content) VALUES ($1, $2)",
    params: ["/automations/weekly-report.js", source],
  },
  {
    sql: "INSERT INTO lix_file (path, content) VALUES ($1, $2)",
    params: ["/media/launch.mp4", video],
  },
  {
    sql: "UPDATE orders SET status = 'shipped' WHERE id = $1",
    params: [1002],
  },
]);

// Branch, diff, and roll back all of it together.

Give each customer a repository

Your customers want agents that write automations and edit their documents, with a way to review and undo. Drive has no version control. Your customers do not have GitHub repos. Embed Lix and give each customer a repository that holds their code, documents, spreadsheets, and media.

typescript

// One hosted repository per customer.
const lix = await openLix({
  server: {
    url: `https://example.com/lix/${customer.repositoryId}`,
  },
});

// The agent writes an automation. Lix commits the change automatically.
await lix.execute("INSERT INTO lix_file (path, content) VALUES ($1, $2)", [
  "/automations/booking.ts",
  code,
]);

// Your UI shows the diff. The customer clicks accept or undo.

Apps with version control

Your app reads and writes SQL rows and normal files. Lix records every change with its author, so history, blame, branching, and rollback are queries instead of features you build.

typescript

// A normal app write. "orders" is a table you registered with a Lix schema.
await lix.execute("UPDATE orders SET status = 'shipped' WHERE id = 1002");

// The history sidebar, diff view, and undo button are queries:
const changes = await lix.execute(`
  SELECT created_at, account_id, schema_key, row_pk, snapshot_content
  FROM lix_change
  ORDER BY created_at DESC
`);
