Agent Relay
Agent Relay is an open source tool that connects AI coding sessions from different vendors to work together.
Agent Relay connects AI coding sessions from different vendors so they can work together while you stay in charge. One session leads and the other follows, while the relay passes each turn across, records it on disk, and stops when something needs a decision. It is tested with Claude Code and Codex, and you can write adapters for other agents. It features a web console, an on-disk message store, adapters, and a controller that enforces budgets and timeouts. It is designed for developers who want to coordinate multiple AI coding tools without manually transferring context.
