Original: downbeat: stop copy-pasting between your AI terminals
Short summary
downbeat is a local, filesystem-backed message broker that lets parallel AI coding sessions on the same machine hand tasks to each other without manual copy-pasting. It uses JSON files in inbox directories as transport, with a two-phase delivery state machine (delivered then acknowledged) to prevent silent message loss, plus a TUI for monitoring traffic. The tool is open-source, installs via PyPI, and keeps humans in the loop by default — nothing auto-executes without explicit user action.

- •Human-in-the-loop by default; installs via PyPI with no cloud or account needed
Generated with AI, which can make mistakes.
Is this a good recommendation for you?
