forge
Solo devs ship like teams.
Forge is an open-source framework for spinning up Sonnet-powered AI sub-agents — reviewers, refactorers, testers, researchers — and orchestrating them from a single Python, Node, or Rust process.
Install in your language.
One SDK, three runtimes. Same agent primitives, same backend.
$ pip install forgefrom forge import Forge
forge = Forge()
agent = forge.spawn("reviewer", model="sonnet")
result = agent.run("Review src/payments.py for race conditions")
print(result.summary)Why Forge.
Solo-dev OSS
MIT-licensed. Built for the one-person shop. No enterprise dashboard, no seat licensing, no sales call.
Multi-agent under the hood
Each sub-agent runs in its own context with its own role and tools. Spawn a reviewer, a tester, and a writer — they coordinate, you don't babysit.
Self-host or use ours
Run the Forge Brain backend on your own box, or point at our hosted endpoint. Switch with one env var.
