Hey HN! I’m Rasmus, co-founder of Flytrap. Flytrap is a debugging tool for reproducing and fixing production bugs faster. When launching a product quickly, there is bound to be some bugs. Tools like Sentry might help combat this, but when a bug lands in Sentry, all you see is the Red Carpet of Doom (the stack trace). We were frustrated with the poor developer-experience of current debugging tools, and decided to build Flytrap; a fast debugging tool that quickly allows developers to understand in detail what happened leading up to a bug, and focuses on reproducibility in the developer…

Hey HN! We’re open-sourcing highlight.io (https://github.com/highlight/highlight), a session replay and error monitoring tool. Highlight.io gives you a high-precision video-like replay of what users are doing when an error or exception occurs in your web app, along with a full-fledged error monitoring experience (similar to bugsnag, rollbar, etc..). The main value prop of highlight.io is that we help you understand the full context surrounding an error and allow you to drill down to the code path that a user invoked (i.e user clicked button X, sent network request Y, and…

Hi HN community, Over the last six months, we’ve been building FlyCode, a product editing DevTool. We make it easy for team members to edit product copy in web and native apps’ code through FlyCode’s dashboard with auto-generated PRs instead of using a code editor. From the beginning, we built around the belief that codebase ownership should stay with developers and that tools should flexibly coexist with a codebase rather than dictate infra changes. The key shift for us was to identify ways to include non-technical teams as individual contributors in the development process. At FlyCode,…

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…

Hi HN! I’m Gabriel, and I’m happy to share a project I’ve been working on for the last few years: Flyde, an open-source visual programming language. Check out the interactive examples and online playground on the website: https://www.flyde.dev. In my last role as an engineering manager for a B2B-oriented product, I authored and reviewed many diagrams for backend applications, mostly for integrations between 2 third-party services. Some of these diagrams were elaborate enough that I started dreaming of a way to simply run a diagram as is; I imagined a “run” button on the top-right…
