Acyclic

Acyclic is a command-line tool that splits coding tasks across parallel agent sandboxes.

Acyclic runs rapid agent swarms to make agentic workflows faster. It splits a task across multiple coding agents in separate sandboxes, which work in parallel and merge into one patch or pull request. Users run the command-line tool inside their project to upload working files and watch agents live. Alternatively, users can start a swarm from the dashboard or connect a coding agent over MCP. It is built for startups building domain-specific agents, companies operating swarms in production, and teams running Claude Code or Codex sessions on large codebases.
