Seer is our AI agent that takes bugs and uses all of the context Sentry has to find the root cause and suggest a fix. We use it all the time to help us improve Sentry. Seer fixes Sentry. More recently, Seer has been helping us fix itself — Seer fixing Seer. An upstream outage triggered a bit of an avalanche, revealing a bug that had been hiding away for months. When it came time to fix it, Seer pointed us exactly where we needed to look.

Session Replay. Structured logs. AI monitoring. Automatic OpenTelemetry tracing. Feature flag tracking. If you haven't seen these in your Sentry dashboard, your SDK version is probably the reason. Whether you're on @sentry/react, @sentry/nextjs, @sentry/vue, @sentry/angular, @sentry/sveltekit, or any other @sentry/* package, they all version together. When we say v10, we mean all of them.

Have you noticed AI recently? Yeah, us too. Generative AI is wreaking havoc on the software status quo, and that includes licensing, and that generates … opinions. Sentry has a long history of having opinions about software licensing. We started life as an unlicensed side project in 2008, then went through BSD, to BSL, to writing our own license, FSL.

With AI writing more and more of our code, properly monitoring and debugging that code has become an increasingly critical part of the development workflow that can't be ignored. Luckily, we have more time than ever to implement the right tools to do so. Implementing a production-ready logging solution is easy to do, and provides you and your LLM Agents with a wealth of debugging information from your app, across users and environments.

If you've already instrumented your app with OpenTelemetry, you don't have to rip it out to use Sentry. Two environment variables and your logs start flowing into Sentry, no SDK changes, no re-instrumentation. Here's how to set it up in a sample app, and when the native Sentry SDK might be the better call.

We just released React Native SDK 8.0.0, here's what's new, and what's changed. It's been a while since the last major version. The last major release, 7.0.0, shipped on September 2, 2025. After 13 minor and 2 patch releases, it's finally time for a new major version to land: 8.0.0. This version is a maintenance and capability major. This means we: It should be straightforward to upgrade, but check the migration guide for your setup.

When you ship a Next.js app, the React and TypeScript you write aren’t what your users actually download. Next.js compiles, minifies, splits, and shuffles your code into chunks in ways that are great for performance and terrible for debugging. This post shows you how that pipeline works, how source maps and debug IDs connect it all back to your original code, and how to wire things up so Sentry shows you real file names and line numbers instead of an unreadable stack trace.

The things that separate a minimum viable product (MVP) from a production-ready app are polish, final touches, and the Pareto 'last 20%' of work. Most bugs, edge cases, and performance issues won't show up until after launch, when real users start hammering your application. If you're reading this, you're probably at the 80% mark, ready to tackle the rest.

Today we're announcing that Sentry has acquired XcodeBuildMCP, an open source MCP server that gives AI agents the ability to build, test, and debug native iOS and macOS apps. XcodeBuildMCP has become a go-to tool for agentic Apple-platform development, with more than 4,000 GitHub stars and an active community. It unlocks the full developer loop: build, run, debug, interact, and verify, allowing users to stay in their preferred agentic development environment.

Sentry acquired Emerge Tools in May 2025 to bring best-in-class mobile tooling to dev teams. Today, we’re officially bringing Size Analysis - one of their flagship products - to all Sentry users, so you never have to worry about app size again.
