Freebuff
Open-source terminal coding agent that coordinates sub-agents. Formerly Codebuff.
Open-source terminal AI coding agent that coordinates specialized sub-agents to make precise multi-file edits from natural language, renamed from Codebuff to Freebuff and now spanning a CLI, a desktop app, a browser surface and GitHub. Its own published evals report 61% vs 53% against Claude Code over 175+ tasks — their number, not ours. Attaches over the SDK pattern.

What “Beta” means for Freebuff
The integration path is built and tested. Real customers can attach now, but expect minor breaking changes until the 1.0 contract freeze.
How it attaches
SDK / Library.
Install the @trustvice/actor-codebuff package and call witness.attach() once during agent initialisation.
Install the Trustvice adapter package from npm, PyPI, or cargo and call witness.attach(agent) in your application.
npm install @trustvice/actor-codebuff
- 1
Install the adapter
Add @trustvice/actor-codebuff to your project from npm.
- 2
Issue a workspace API key
Generate a twk_-prefixed key in the dashboard under Settings → API Keys, scoped to the workspace and environment this agent's data should land in.
- 3
Attach the witness
Call witness.attach(agent) once when you initialise your Freebuff agent. The adapter registers the framework callbacks, handles retries, and performs the workspace handshake.
- 4
Verify
Trigger one agent run. The dashboard's Witness page shows the canonical record within ~1 second of the agent emitting it.
npm install @trustvice/actor-codebuff
Coverage
2 event types captured.
agent.invocationEvery top-level agent run — the input, the resolved output, timing, and token usage.
tool.callEach tool / function the agent invokes, with arguments and the returned result.

SDK / Library — end to end.
Every framework on this pattern shares the same platform-side spine, endpoints, and gotchas. The pattern guide covers them in full.
