Bugsnag - Exception tracking app with open source plugins

In plain words

Bugsnag is an exception and performance tracking tool for mobile and web applications that detects crashes, slowdowns, and errors in real time. It helps development teams identify bugs quickly, trace issues across their entire stack, and prioritize problems by severity and user impact. The platform provides a stability score to guide deployment decisions and captures issues during critical user moments like purchases or transactions, enabling faster fixes and more reliable releases.

Mobile and web app monitoring that helps development teams find bugs instantly, fix them quickly, and deploy stable releases. Monitor crashes, track performance bottlenecks, and trace requests across your entire stack while a stability score tells you when to ship versus when to fix. Every ANR and unhandled exception is potentially lost revenue. BugSnag catches crashes and slowdowns across critical customer moments - making purchases, streaming videos, or booking hotels - and prioritizes issues by severity and user impact to keep customers converting. Get to the root cause quicker. Bugs are captured and prioritized by severity so you know what to fix immediately. SmartBear's MCP server…from bugsnag.com

  Most users won't report bugs unless you make it stupidly easy2025 · bugdrop.app · ▲335

  Most feedback tools are built like people actually want to report bugs. They don’t. Unless you make it dead-simple, or better yet - a little fun. After shipping a few SaaS products, I noticed a pattern: Bugs? Yes. Bug reports? No. Not because users didn’t care but because reporting bugs is usually a terrible experience. Most tools want users to: * Fill out a long form * Enter their email * Describe a bug they barely understand * Maybe sign in or create an account * Then maybe submit it Let’s be real: no one’s doing that. Especially not someone just trying to use your product. So I built…

  Talanoa▲341

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
