LiveRecorder for C/ C++ & Go

Record and replay the execution of your software

Debugging intermittent failures - whether in development, test or in production - takes time. It slows down development projects and frustrates customers...

What if you could record your program's execution as it fails and replay the recording offline any time anywhere?

Capture software failures ‘in the act’

Replay the recording and get instant visibility into what your program did and why

Debug the recording instead of the live program

Record functionality

Record programming errors

LiveRecorder captures all non-deterministic data (down to instruction level) and recreates your application’s entire memory and the register state - on demand and with minimal overhead.

It offers root-cause diagnosis capabilities without the need for a reproducer.

LiveRecorder's core recording technology is language independent and compatible with most mainstream Linux distributions.

100%

Failure reproducibility

Get to the root cause of software defects quickly and with absolute certainty

10x

Faster Time-To-Resolution

Solve challenging software defects 10x faster than with traditional debugging methods

6 months

ROI within 6 months

Undo's technology found to pay for itself in the above time frame when deployed on mission critical systems

Replay functionality

Debug the recording

Once you have the recording file capturing a defect, you can view the recording to analyze execution history using UDB, LiveRecorder's replay engine .

Key features

LiveRecorder features

LiveRecorder accelerates software defect detection and resolution.

Faster than you think

Without specialized technology, recording large systems would be slow and unusable. With LiveRecorder, expect to see 2x - 5x slowdown on most programs. You only need to record the failed processes (not all of them) - and you only need to record once to get all the data you need to analyze later.

Time Travel Debugger

Replay recordings forwards and backwards to analyze internal state. Breakpoints, bookmarks, notifications make it easy.

Multi-Process Correlation

Reveals the order in which processes and threads alter data structures in shared memory.

Thread Fuzzing

Randomizes thread execution to reveal race conditions and other multi-threading defects.

Integration & Control

APIs, CLI, front-end & container platform integrations help you automate and enrich QA & CI processes.

Compiler- and library-agnostic

We don’t require the application to be recompiled or linked against particular libraries.

Log Jump

A powerful method for developers to jump from a log line of interest to the corresponding point in time in a LiveRecorder recording.

Post Failure Logging

Feature that generates log files after a software failure occurs. The log files can be debugged, remotely, without the recording file ever leaving the end-customer’s secure environment or IP/ IIP sensitive data being exposed.

Competitor comparison

LiveRecorder vs traditional debugging

LiveRecorder is the only solution that gives you data-driven insight into what your software really did before it failed. No need for a reproducer. You have the whole movie in your hands, which you can then replay in slow motion forwards and backwards.
