Your agents are moving fast. Know what needs you.

Build brings your coding agents into one workspace, with questions, progress, and changes ready for your review. Run them on your machines. Stay in control from any screen.

Build’s Tasks dashboard on a laptop, with three tasks under Needs you

02 / One place

See your agents in one place.

See what your agents are doing, what they changed, and which ones need an answer. Run Claude Code, Codex and Pi together in Build.

  • Your agents run on your computer.
  • Your files stay there.
  • Build's servers cannot read your code or prompts.

Model requests still go to the providers you configure.

03 / Tasks

Write the task. Hand it off.

Write a task and assign an agent. Start it in a separate workspace on your machine. Follow its progress on the board, from Backlog to Done.

04 / Questions

See which agent needs an answer.

Agent questions appear in your inbox. Open one on your phone, reply, and the agent can continue. Turn on notifications to hear when an agent needs you.
