About
Relay is a harness for coding agents that loops on a task: it attempts the change, runs checks in a fresh isolated sandbox, and on failure reads the error and retries until the checks pass. It retains what it learned to avoid repeating mistakes and ships the result as a normal git PR. It plans and reviews with a top-tier model and writes code with cheaper ones, runs locally without an account, and has a paid tier for unattended multi-repo runs.
At a glance
Relay queues coding tasks in separate Git worktrees and reruns the repository’s checks before treating work as done. It is worth a trial if you have a reliable test suite and want to hand off a small backlog without supervising every command.
Good fit
Developers who can define a clear test, lint and build contract for an isolated task.
Consider something else when
Skip it if the repository has weak checks or its policy bars a closed-source harness.
Start here
Use a disposable repository. Review the proposed branch, check commands and run budget, then hand off one failing test and inspect the resulting diff and check logs.
Cost and requirements
Relay documents a free single-repository local queue, paid options for unattended runs and sandbox checks, and separate model access through your provider.
Limits to know
A green suite covers the behavior your checks exercise. The vendor’s comparisons vary by task and configuration, so measure the benefit on your own work.
