Smarter debugging with Sentry MCP and Cursor

Jul 31, 2025 By Cody De Arkland In Sentry
Debugging a production issue with Cursor? Your workflow probably looks like this: Alt-Tab to Sentry, copy error details, switch back to your IDE, paste into Cursor. By the time you’ve context-switched three times, you’ve lost your flow and you’re looking at generic suggestions that don’t show any understanding of your actual production environment or codebase.

Introducing new issue detectors: Spot latency, overfetching, and unsafe queries early

Jul 30, 2025 By Sasha Blumenfeld In Sentry
Not everything in production is on fire. Sometimes it’s just... a little warm. A page that loads a second too slow. An API that returns way more than anyone asked for. A query that feels totally fine until someone sends something unexpected and suddenly you’ve got an incident.

Evals are just tests, so why aren't engineers writing them?

Jul 29, 2025 By Eli Hooten In Sentry
You’ve shipped an AI feature. Prompts are tuned, models wired up, everything looks solid in local testing. But in production, things fall apart—responses are inconsistent, quality drops, weird edge cases appear out of nowhere. You set up evals to improve quality and consistency. You use Langfuse, Braintrust, Promptfoo—whatever fits. You start running your evals, tracking regressions, fixing issues, and confidence goes up as a result. Things improve.

How Sentry could stop npm from breaking the Internet

Jul 25, 2025 By Lazar Nikolov In Sentry
Caching is great! When it works… When it fails, it puts a big load on your backend, resulting in either a self-inflicted DoS, increased server bills, or both. This article is inspired by a real-world incident that happened to npm back in 2016. In the next part, Ben recounts his personal experience responding to the incident while working at npm.

Introducing Sentry's Godot SDK 1.0 Alpha, with support for Godot 4.5 Beta

Jul 23, 2025 By Steve Zegalia In Sentry
Debugging during development is easy. You've got a debugger, stack traces, and logs right in front of you. But once your Godot game is in the hands of players, things get trickier. Most won’t report bugs, and if they do, you’re lucky if they include anything more than “it crashed”.

Want to hear your users' complaints? There's a widget for that (now available on mobile)

Jul 10, 2025 By Steve Zegalia In Sentry
A disappearing “Submit” button. A modal stuck half-offscreen. It's not a crash or a performance regression. Just broken UX. Frustrating enough to make users rage-quit or leave a 1-star review. Error and performance monitoring catch the technical stuff: crashes, bottlenecks, slow APIs. But they won’t tell you when a layout breaks, or a UI flow subtly unravels after a redesign.

What You Actually Need to Monitor AI Systems in Production

Jul 9, 2025 By Rahul Chhabria In Sentry
You did it. You added the latest AI agent into your product. Shipped it. Went to sleep. Woke up to find it returning a blank string, taking five seconds longer than yesterday, or confidently outputting lies in perfect JSON. Naturally, you check your logs. You see a prompt. You see a response. And you see nothing helpful. Surprise. Prompt in and response out is not observability. It is vibes.

An open-source SDK for finding dead code

Jul 8, 2025 By Noah Martin In Sentry
Writing code is easier than ever. We want to make deleting code just as easy – introducing Reaper for iOS and Android. Reaper was an Emerge Tools product that helped companies like Duolingo delete 1% of their iOS codebase. And just like with Emerge Tools’ Launch Booster, we’re making Reaper open-source for anyone to use. In this post, we’ll explain what Reaper is, why you should care about dead code, and how Reaper works on both platforms.

Robust Time Series Monitoring: Anomaly Detection Using Matrix Profile and Prophet

Jul 2, 2025 By Ram Senthamarai In Sentry
Monitoring production systems often feels like searching for a moving needle in a constantly shifting haystack. At Sentry, our goal was to empower customers to move beyond traditional threshold and percentage-based alerting. We aimed to help them detect subtle and complex anomalies in their systems in near real-time. This post will detail how our AI/ML team developed a time series anomaly detection system using Matrix Profile and Meta’s Prophet.
