Run Claude Code in ace

Anthropic's coding agent, run from its own command-line tool. ace runs it through your own signed-in CLI and adds what a terminal can't: every task in its own thread, a status that covers its subagents, and tools to see and test what it builds.

What Claude Code gets in ace

  • Subagents and background shells Claude Code starts count toward the thread's status, so the thread says Waiting until they finish.
  • Permission prompts show as Approve in the thread, on your desktop and on your phone.

  2. Download ace for your computer and open a project folder.
