Watch your AI agents work.Step in when it matters.

Sulcus shows each run step by step: what your agent called, how long it took and where it went wrong.

Free during early access.

The Sulcus home screen with sample data. Under Needs you, one Claude Code request to run git push waits for approval, with Deny and Approve buttons. Under Running now, five agents: Claude Code waiting for that approval, a LangGraph run, a custom agent, Codex and an idle Cursor session.
Sulcus, with sample data.

More than a trace.

Tracing shows what an agent did. Sulcus also lets you act while it runs.

  • See it

    Agents, steps, model calls and tool calls, in the order they happened.

  • Step in

    Stop a hosted run, or give it a token limit.

  • Look back

    Every run keeps its history, so you can see what happened and where it failed.

When an agent asks, you decide.

Claude Code, Codex and your own agents can wait for your answer before they act. Sulcus never approves for you.

Bring the agent you already have.

No agent yet? Try ours.

Our LangGraph demo is slow on purpose and needs no API key. Run it, watch it, stop it, or let a token limit end it.

See your own agent in Sulcus.

Sign up, point Sulcus at your agent and watch its next run.
