Acyclic

Acyclic splits a task across many coding agents, each in its own sandbox and instant fork of the workspace, runs them in parallel, and merges the results into one patch or pull request, so long agentic workflows finish in a fraction of the time. Start a swarm from the CLI, the dashboard, or a coding agent over MCP, watch every branch live, fork the ones worth exploring, and keep only the results you verified. The CLI uploads your working files without history or secrets, and you apply the merged patch locally or open a PR. Bring your own model keys. Built by Acyclic Labs, a Y Combinator company.
