Replicas
Run background coding agents in secure cloud sandboxes.
What it does
Spins up sandboxed virtual machines with repositories cloned and dependencies installed. Executes autonomous coding agent harnesses like Claude Code or Codex in the background. Runs applications locally, verifies test suites, and iterates on bug fixes. Opens GitHub pull requests automatically and syncs progress back to project management boards.
Why it works
Sandboxed execution environments allow safe, local code compilation and testing. Brings your own credentials to support flexible agent frameworks like Claude Code and Codex. Triggers seamlessly from existing team workflows like Linear, Slack, and GitHub. Automates repetitive ticket resolution to parallelize engineering work effectively.
