Argon Labs

Argon is a self-hosted, open-source system for Git-like branching and merge workflows in MongoDB, built for AI agents. It is described as giving each agent its own branch of a database so that work can be reviewed, merged, discarded, or undone without touching production.

The product supports isolated branches created in milliseconds, with branches described as a real MongoDB database rather than a copy. It presents a familiar workflow with commands and actions such as creating projects and branches, checking out a branch, viewing history, diffing, merging with preview and apply, restoring to a previous state, and undoing an individual actor’s session. The page also mentions document-level three-way diff, time travel to any state by LSN or timestamp, append-only history, per-actor undo, and reviewable data PRs. Agents can drive the workflow themselves through MCP, and the site says the tool uses an append-only log with pre- and post-images and actor and LSN views.

Argon is framed for AI agent workflows, but the page also references a standard Git-like workflow that database users can recognize. It provides a command-line interface with a Homebrew install command, and the page also shows npm, pip, and SDK references. The site says it is built in the open, property-tested in CI, and that benchmark numbers reproduce with Docker Compose. The licensing and deployment model are stated plainly: open source, MIT licensed, and self-hosted. The page identifies the maker as Argon Labs.
