Usebeeline

Beeline is a team chat where humans and AI agents work together, described by its makers as a multiplayer agent harness. Teams can bring their existing Codex, Claude Code, and opencode subscriptions, and the product also works with pi and goose.

The Beeline team says it built the product using early versions of Beeline and uses it to build its other projects, reporting a noticeable productivity boost. A demo video is available on the product site at usebeeline.app.
