24 alternatives to Flytrap – Debugging tool for fixing production bugs
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! We are presenting CodeTracer - a user-friendly time-traveling debugger designed to support a wide range of programming languages: https://github.com/metacraft-labs/codetracer?tab=readme-ov-f... CodeTracer records the execution of a program into a sharable self-contained trace file. You can load the produced trace files in a GUI environment that allows you to move forward and backward through the execution and to examine the history of all memory locations. They say a picture is worth a thousand words — well, a video is even better! Watch the demo below to see…

Hey HN, I wanted to show you a product a small team and I have been working on for 4 years. https://jam.dev It’s called Jam and it prevents product managers (like I used to be) from being able to create vague and un-reproducible bug tickets (like I used to create). It’s actually really hard as a non-engineer to file useful bug tickets for engineers. Like, sometimes I thought I included a screenshot, but the important information the engineer needed was what was actually right outside the boundary of the screenshot I took. Or I'd write that something "didn't work" but the engineer…

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,…

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…

bugstack▲76Hey HN, bugstack started life as an internal tool for my other startup Fuelscout because my customers would encounter production bugs when I was away that would ruin their experience. When I went camping and came home to find out my internal tool had fixed an error and shipped it to production I knew it was bigger than Fuelscout, so my little tool became bugstack. bugstack monitors your production errors 24/7. When a user hits a bug, bugstack captures the error, pulls context from your repo, generates a minimal surgical code fix, runs it through CI, and delivers it as a pull request. If…

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…

I'd like to invite everyone to try out DontBeEvil.rip, an experimental search engine for developers. tl;dr $ alias rip="curl -G -H 'Accept: text/plain' --url https://dontbeevil.rip/search --data-urlencode " $ rip 'q=Heartbleed bug' DontBeEvil.rip is a year long experiment to see if a small team can build a developer-focused search engine that is self-sustaining on $10 monthly subscriptions. It works by only indexing high-quality resources that are relevant to developers. You won't get useless listicles because we'll never crawl them. Relevant urls are harvested from HN,…

Hi HN! We’re Adrien and Kanav. We met at our previous job, where we spent about a third of our lives combating a constant firehose of bugs. In the hope of reducing this pain for others in the future, we’re working on automating debugging. We’re currently working on a platform that ingests logs and then automatically reproduces, root causes and ultimately fixes production bugs as they happen. You can see some of our work on this here - https://news.ycombinator.com/item?id=39528087 As we were building the root-cause phase of our automated debugger, we realized that we developed…

FlowLens▲134Hi HN, We often run into this with coding agents like Claude Code: debugging turns into copy-pasting logs, writing long explanations, and sharing screenshots. FlowLens is an MCP server plus a Chrome extension that captures browser context (video, console, network, user actions, storage) and makes it available to MCP-compatible agents like Claude Code. You can try it here: https://magentic.ai/flowlens Any feedback—good, bad, or brutal—is welcome.
