Vercel helps you ship fast. We help you ship safe with code‑first observability that connects errors to the code and deploys behind them. Together you get speed with clear insight into what is running in production. Today we’re launching our native integration in Vercel’s Observability category so you can connect Rollbar to your Vercel projects in minutes, map environments cleanly, and track deployments from day one.

Software teams do their best work when they can move quickly without losing control. That reality has shaped how our product has evolved, and it needed to shape how our brand shows up too. Our refresh is not a new coat of paint. It is an honest reflection of what Rollbar is today and where we are going: a code-first observability platform that helps builders understand what is happening in their code and why, so every release is better than the last.

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.
