Make software errors 100% reproducible with time travel debugging

LiveRecorder for Java enables reverse step out, step into, and step over controls for developers.

UNDO FOR JAVA

Ship applications faster with fewer errors

Undo brings time travel debugging to CI, enabling developers to easily and quickly diagnose the root cause of new regressions, legacy issues, and flaky tests.

Ensure software quality – fix errors before they hit customers
Improve developer productivity by accelerating root cause analysis
Get software releases out on time

Record. Replay. Resolve.

Record application failures in CI / Automated Tests
Replay the recording to get full visibility into what your application did and why
Resolve issues fast

Ideal for quickly fixing:

Concurrency issues e.g. ConcurrencyModificationException
Uncaught exceptions
Data structure corruptions
Logic errors
Communication / protocol errors

Take the guesswork out of debugging

Get answers not alerts – recordings provide complete failure insight data for developers to rapidly diagnose the root cause of errors with 100% certainty

Capture intermittent failures – make intermittent failures 100% reproducible
Microservice interaction – explore the behavior of and communication between microservices
Save time and effort – no need to reproduce the issue or recreate the environment
Shift-left testing – shareable recordings that enable collaborative error resolution across development, QA and staging
Code-level observability – replay and analyze application execution history to understand unintended code behavior
Enhanced understandability – learn and understand codebases you didn’t write

Time travel debugging

Travel backward in time (and forward again) to inspect the program state.

Undo for Java adds additional controls to enable developers to reverse step out, reverse step into and reverse step over.

The full power of a modern debugger with variable and memory inspection, scripting, conditional breakpoints and watchpoints, all available in forward and reverse directions.

CI/CD – Test Automation

Accelerate the debugging and resolution of test failures by integrating Undo into your CI system.

Automate the recording of failing tests
Systematic capture of intermittent failures
Shareable recordings – no more “I couldn’t reproduce that on my machine”
Debug the recording in your IDE
Integrates with all popular build automation tools

Undo works where you work

Record in Test/QA. Replay and diagnose in your IDE.

Undo brings powerful advanced time travel debugging capabilities to IntelliJ IDEA on Windows, macOS and Linux. (in both the Ultimate and Community Editions)

Time travel debugging for teams

Undo enables software teams to create better software faster.

Developer

Fix errors faster without having to search through logs, dive into APM or other tools created for other teams and other purposes. Skip past painstaking guesswork of traditional log-based debugging.

Tester - QA

Go one better than a test failure bug report. Attach a recording to your ticket containing all of the failure data needed for the developer to reproduce and fix the bug.
