Features

Scale autonomous agents without losing developer control. Give agents ground-truth runtime traces, isolated sandboxes, and automated verification.

The agents execute multi-milestone plans

🞴 Advanced anti-halting features and the use of supervisor agents enable the unattended execution of complex plans that may span hours of ordinary agent sessions.

🞴 The agents test their work on multiple operating systems in parallel, declaring a task complete only when the CI passes.

Trace Autopsies

Agents inspect deterministic execution traces via MCP to isolate bugs without hallucinating

Insight

Anti-Halting Supervision

Supervisors guide long-running worker swarms across multi-milestone plans

Insight

AgentHarborFS Sandboxes

Zero-copy lightweight workspaces eliminate git worktree disk bloat and setup delay

Insight

Launch many YOLO agents in parallel

🞴 You can bring your own subscription. We offer flexible support for all models and third-party agents.

🞴 The agents execute within a secure sandbox on macOS, Linux and Windows.

🞴 AgentHarborFS eliminates the setup time associated with git worktrees and ensures optimal disk usage.

“AgentHarborFS completely changed our agent workflow. We spin up dozens of isolated coding agents in parallel with zero git worktree disk overhead, and let them iterate until tests turn green.”

Karthik Raman

Lead AI Architect

“Before CodeTracer, agents would hallucinate function state and loop indefinitely. Giving them ground-truth execution traces via MCP enabled them to pinpoint real bugs on the first attempt.”

Miriam Chen

Staff Research Engineer

“The anti-halting supervisors ensure our multi-hour coding runs never stall. Our agents run overnight and deliver clean, verified pull requests that actually pass CI.”

FAQ

This section covers the most frequently asked questions to give you clarity.

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?

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

Is Windows supported?

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

What’s inside a trace?

The execution trace of your program captures every program state over time.

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. These will be opened in the CodeTracer web IDE.
