What is Undo?

Time travel debugging empowers developers to better understand their codebases and address bugs more rapidly. The Ultimate Debugger (UDB) is recognized as the leading time travel debugger specifically designed for Linux C/C++ applications, enabling teams to confront complex software issues during both the development and production stages at speeds that can be up to ten times quicker. Debugging software problems can often drain resources and disrupt development efforts, leading to negative impacts on user experience. Picture having the capability to capture the exact moment your program fails and then replaying that execution at any time and place to gain insight into what transpired. LiveRecorder stands out as a top enterprise-level Software Failure Replay platform, significantly improving the debugging experience. Furthermore, time travel debugging not only enhances team productivity throughout the development cycle, but it is also invaluable when it comes to diagnosing test failures. Developers can easily maneuver through time, examining the program's state and helping them untangle complex issues while producing higher-quality software more effectively. With Undo’s time travel debugging features, developers can alleviate the challenges of interpreting their code's behavior, thereby streamlining the overall development workflow and boosting efficiency. This cutting-edge approach revolutionizes the debugging process, allowing teams to concentrate on crafting resilient and trustworthy software solutions that meet user needs. By fostering a more intuitive debugging environment, organizations can ultimately accelerate their software development timelines.

What is Perfbase?

Perfbase is a PHP performance monitoring and profiling platform that helps businesses, agencies, and engineering teams identify the true causes of slow PHP application performance. Perfbase supports PHP 7.4 through PHP 8.5 and works across the wider PHP ecosystem, including Laravel, Symfony, WordPress, custom PHP applications, Composer-based platforms, APIs, ecommerce systems, queues, workers, cron jobs, and CLI scripts. It can help teams profile application code, framework internals, Composer packages, vendor libraries, third-party SDKs, middleware, service classes, templates, background jobs, and other PHP execution paths. Many monitoring tools can tell a team that a request is slow, but not always why it is slow. Perfbase provides runtime-level PHP tracing so developers can see where execution time is being spent across methods, functions, libraries, framework code, SDK calls, templates, jobs, crons, and background processes. This is especially valuable when database queries, logs, or framework-level profilers do not explain the full request time. Perfbase helps teams uncover hidden bottlenecks such as expensive service methods, inefficient loops, slow Composer packages, slow SDK calls, serialization overhead, rendering delays, or unexpected work happening inside background tasks. Common use cases include diagnosing slow PHP requests, profiling Laravel and Symfony applications, investigating WordPress performance issues, monitoring cron jobs and queues, finding third-party library overhead, understanding regressions after deployments, and helping teams optimise code before spending more on infrastructure. Perfbase is built specifically for PHP developers and teams that need practical performance insight. It helps reduce debugging time, improve response times, support production troubleshooting, and give developers a clearer view of what their applications are actually doing.
