Record and replay the execution of your Linux program
Debugging a live production system can be pretty hairy. But what if you could record your program's execution as it fails and replay the recording offline?
Program execution recording for Linux applications
Record program execution and generate a recording artifact
Capture all non-deterministic data (down to instruction level) and recreate your application’s entire memory and the register state - on demand and with minimal overhead.
Replay the recording file to analyze execution history
Debug the recording using Live Recorder’s integrated reverse-debugging tool: step backwards as well as forwards in the code to find the root cause of the problem.
Fix the bug and deploy in production
Fix the bug and commit it to your test system. When the test turns green, deploy the fix to your users.
Key facts
About the Undo technology
Live Recorder's underlying technology records non-deterministic data and recomputes deterministic data on-the-fly. Recreate your application’s entire memory and register state on demand, at any point in its execution, and with minimal overhead. And critically, you can see it all just as it happened during the original run – without needing to know in advance what you will want to look at.
Capture the most challenging bugs that cannot be caught any other way
Record and replay program execution and quickly diagnose severe software failures in test or in production

Live Recorder vs traditional software reliability solutions
Static and dynamic analysis tools only find defects they were programmed to seek out; they also highlight too many false positives. Meanwhile, manual debugging is mostly based on guesswork and eats away developer-time. Live Recorder is the only solution that gives you data-driven insight into what your software really did before it failed. Live Recorder can capture intermittent, non-deterministic failures which cannot be tracked down in any other way.
