What is Highlight?
Highlight is an open-source, full-stack monitoring platform that combines session replay, error tracking, logging and performance monitoring so you can see exactly what is happening — and what went wrong — in your application. Instead of piecing together separate tools, Highlight lets you watch a replay of the user's session, see the errors and logs that occurred, and trace performance issues, all in one place. That end-to-end visibility makes debugging production problems dramatically faster, because you can see the user's actual experience alongside the technical details.
Its strengths are breadth and openness. By unifying session replay with error monitoring, logs and traces, Highlight connects the dots between what a user did and what broke, which is often the hardest part of debugging. Being open source, it is transparent, community-driven and self-hostable, giving teams control over their data — important when monitoring can capture sensitive information. It serves both frontend and backend, so you get a coherent picture across your whole stack rather than fragmented signals from disconnected services.
Highlight is ideal for developers and teams who want comprehensive, full-stack observability — replay, errors, logs and performance — in one open platform, and who value the option to self-host for data control. It sits alongside established monitoring tools but distinguishes itself with session replay and an open-source foundation. If you want to understand and fix issues quickly by actually seeing what your users experienced, with full visibility across frontend and backend, Highlight is a powerful, transparent choice for keeping your application healthy.
What is Sentry?
Sentry is the application monitoring platform that developers reach for when they need to know — instantly and in detail — what's breaking in production. Rather than waiting for a user to complain about a vague "it's not working," Sentry captures every error and performance issue the moment it happens, complete with the full context an engineer needs to fix it: the stack trace, the line of code, the release it shipped in, the device and browser, and the exact sequence of events that led to the crash. It turns the frustrating detective work of debugging into a guided, evidence-rich process.
Beyond error tracking, Sentry covers performance monitoring and session replay, so you can see not just that something failed but why your app feels slow and what the user actually experienced. Distributed tracing follows a request across services to pinpoint the bottleneck; session replay lets you watch a reconstruction of the user's session leading up to an error; and intelligent grouping and alerting make sure your team hears about the issues that matter without drowning in noise. It integrates with the tools teams already use — issue trackers, chat, CI/CD — so an error can flow straight into a ticket with all its context attached.
Sentry supports virtually every major language and framework, from JavaScript and Python to mobile platforms, which is why it's trusted by individual developers and huge engineering organisations alike. The payoff is faster resolution and higher reliability: teams catch regressions before they spread, understand the real-world impact of each bug, and ship with the confidence that they'll know immediately if something goes wrong. For any team running software that real people depend on, Sentry is the difference between flying blind and having a clear, actionable view of your application's health at all times, which is why it has become a default part of the modern development stack for teams that care about reliability.
