What is LixRay?#

LixRay is a host for Lix repositories.

Lix is a repository designed for work outside software engineering: files, a database, and version control over both. Git tracks changed lines in text files. Lix tracks semantic changes in any file format: the row that changed in a CSV, the paragraph that changed in a Markdown file, the slide that changed in a deck. Plugins map each file format to entities, and every entity change is recorded with who made it, when, and what exactly changed.

Because changes are semantic, diffs are real diffs (cell by cell, paragraph by paragraph) instead of byte blobs, and any change is reversible to any point. People and agents share the same repository and see changes as they happen.

LixRay adds:

  • Hosting: repositories are stored, versioned, and available at a URL.
  • Browser UI: read, edit, and review changes without local tooling.
  • Sharing: every file has a URL; read-only by default, edit by invite.
  • Agent access: agents connect over MCP with OAuth-scoped permissions.

Today the host powers the LixRay app at lixray.com. In the future it can back anything built on Lix that wants hosted, shared repositories without running its own infrastructure. If you want to build on top of LixRay, email [email protected].

Internal apps#

Lix repositories have a SQL interface and JavaScript bindings. Companies can build internal apps on top of their repository: a task tracker, an approval queue, or a dashboard alongside the files and context their teams already use. Application data can share the repository's version history.

Build a mini app to try it with a small task tracker.
