Features

Review code with full runtime context. Inspect the actual values that flowed through every changed line during test execution.

Immediate Code Coverage and Inline Variable Visualization

Review the actual values that have flown through every line during the CI/test executions.

Available in GitHub and CodeTracer Desktop

CodeTracer meets you where you are. DeepReview support for our VS Code extension is coming soon.

TBD???

Instead of a stack trace limited to a single moment in time, CodeTracer shows you the entire tree of function calls in the recorded execution. You can navigate and filter it in various ways and the clever collapsing and expanding algorithms still allow you to obtain a classic stack trace whenever you need it.

Immediate Code Coverage and Inline Variable Visualization

Review the actual values that have flown through every line during the CI/test executions.

Trusted by product builder persons

“Reviewing pull requests used to involve guessing what edge-case inputs would do. With DeepReview, I see the live runtime values and coverage right beside the diff. It cuts PR review time in half.”

Sophie Martin

Staff Backend Engineer

“DeepReview bridges the gap between static code reviews and dynamic testing. You know immediately whether new branches were actually exercised in CI.”

Daniel Zhao

Head of Developer Experience

“Our team will never go back to blind diff reviews. Seeing variable histories in the GitHub PR gives senior engineers confidence to approve AI-generated code.”

Liam Gallagher

Engineering Director

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.
