LIZARD IZ A Replay Debugger

Lizard is a debugger that lets you step forwards as well as backwards through the execution of your program.

You first invoke the tracer, which runs your program to completion while collecting information along the way; then you invoke an interactive replayer, which uses the trace data to allow you to step forwards and backwards.

See the feature list for what else you can do with Lizard, and the technical overview for how it works.
