On your machine
gprdaemon stays connected over websocket- Agent processes spawn locally over ACP stdio
- Git worktrees and branches live on disk under your workspace
- Your existing toolchains, tests, and credentials apply
In the cloud
- User auth (Firebase)
- Task board, queue, and state machine
- Websocket hub / ACP frame relay
- Optional OAuth tokens for GitHub, Jira, Slack
- Push notifications and other app APIs
What that means
The relay sees ACP traffic needed to drive the session from your phone. It is not a substitute for the agent runtime.
