Everything you need to replay a program run and understand exactly what happened — across languages, forwards and backwards.
Record once and every value, branch and call is available to inspect at any point in time.
Step forwards and backwards through the run — the debugger cursor moves in both directions.
Every variable, at every point in time, is already recorded. Inspect any moment without re-running.
Ask where a value last changed and land there instantly, instead of setting breakpoints and guessing.
Walk the full call tree of the execution and dive into any frame as it was at that instant.
Attach replays to a pull request as links — reviewers open them in the CodeTracer web IDE.
Call agents from inside CodeTracer, or bring your own, to reason over a recorded run.
Just move through time and watch the state change around each line. The whole run is a fixed recording you can explore.
Point an agent at a recorded run and let it reason over real execution — while you keep the ground truth of the trace.
