Debugging JavaScript errors just got easier. Today, we're launching Session Replay for Rollbar, giving you visual context for every error with customizable triggers and the only open-source MCP integration that lets AI analyze your sessions directly in your IDE.

Session replay vendors love talking about features and pricing, but rarely publish the technical specs that matter most to developers. We analyzed the actual JavaScript bundles and their performance impacts across five major platforms. You know what's wild? Bundle sizes range from 36KB to over 550KB gzipped. That's the difference between imperceptible impact and noticeable slowdown for your users.

The NumberFormatException is one of the most common runtime exceptions you'll encounter in Java. It's an unchecked exception that occurs when you try to convert a string to a numeric value, but the string format isn't compatible with the target number type. Simply put, if you attempt to parse "hello" as an integer or "12.5" as an integer, Java throws a NumberFormatException because these strings can't be converted to the expected numeric format.

We’re excited to share that Rollbar is now part of the ilert integration catalog! This new technical partnership allows software teams to detect application errors in real time with Rollbar and instantly respond using ilert’s powerful alerting and incident management features. What is Rollbar? Rollbar is a comprehensive, real-time error monitoring and debugging platform designed to help development teams detect, diagnose, and resolve issues faster—before they impact users.

"Imagine spending hours manually sifting through error logs, trying to pinpoint the root cause of a critical issue. This is a common challenge in software development." This is a problem that many engineers experience today and this process can be greatly improved an automated using AI agents. These AI agents will require as much context about the issue or problem as possible to be effective and have any opportunity to help improve this process.

Searching through error data efficiently is critical for developers using monitoring tools. At Rollbar, we recently completed a significant overhaul of our Item Search backend. The previous system faced performance limitations and constraints on search capabilities. This post details the technical challenges, the architectural changes we implemented, and the resulting performance gains.

When software errors strike, developers must act fast. Efficiently triaging issues can drastically reduce downtime, improve user experience, and keep your development team focused on innovation. Rollbar offers powerful features designed to help teams streamline error triage and resolve issues quickly. Here's how you can master the triage process and leverage Rollbar to reduce time spent debugging.
