Features

Let agents run — keep the ground truth.

Point an agent at a recorded run and let it reason over real execution, while you stay in control of every step.

Multi-milestone execution

Complex, unattended plans that run for hours.

Advanced anti-halting features and supervisor agents keep long, multi-step plans moving — confirming completion only when CI actually passes.

  • →Anti-halting supervisors keep agents on task
  • →Work is tested across multiple operating systems
  • →Done means CI is green, not merely 'finished'
✦ plan
Parallel deployment

Run many agents safely, side by side.

Bring your own subscription with flexible model compatibility, and run agents in secure sandboxes on macOS, Linux and Windows.

  • →Bring your own model subscription
  • →Secure sandboxed execution on macOS, Linux & Windows
  • →AgentHarborFS cuts setup time and disk usage

FAQ

Frequently asked questions.

Do reviewers need the desktop app?+

Only when reviewing replays for C/C++, Rust and other natively compiled languages on Linux. Replays for Python, Ruby and other interpreted languages can be fully explored in the CodeTracer web IDE.

What languages are supported today?+

Python and Ruby (Linux & macOS, with full web replay), plus C/C++, Rust and others (Linux desktop replay). New languages are added frequently.

Is Windows supported?+

Desktop replay runs on Linux today, with macOS support for the interpreted languages. Windows support is on the roadmap — reach out if it matters to your team.

What's inside a trace?+

The execution trace of your program captures every program state over time, so you can replay and inspect the whole run deterministically.

Can I use my own AI agent?+

Yes. You can call agents from within CodeTracer or use external agents.

Can I attach multiple replays to a single PR?+

Yes — you can attach an arbitrary number of replays as links. They open directly in the CodeTracer web IDE.
