We vibe coded our team's issue tracker, knowledge base, telemetry board
Hi HN, I'm the CEO at https://replay.io. We've been working on time travel debugging for web development for a while (https://news.ycombinator.com/item?id=28539247) and more recently an AI app builder that uses that debugger to get past problems instead of spinning in circles (https://news.ycombinator.com/item?id=43258585). We've gotten to where we can pretty easily build apps to replace business-critical SaaS tools, some of which we're now using internally: * We built our own issue tracker to keep track of all our development projects, tickets, bug…
What it does
In the maker’s words, at launch
Hi HN, I'm the CEO at https://replay.io. We've been working on time travel debugging for web development for a while (https://news.ycombinator.com/item?id=28539247) and more recently an AI app builder that uses that debugger to get past problems instead of spinning in circles (https://news.ycombinator.com/item?id=43258585). We've gotten to where we can pretty easily build apps to replace business-critical SaaS tools, some of which we're now using internally: * We built our own issue tracker to keep track of all our development projects, tickets, bug fixes, and so on, completely replacing Linear. * We built a knowledge base for managing internal documentation and the status of ongoing initiatives, completely replacing Notion. * We built a telemetry system that ingests OTLP events via a webhook and supports custom graphs and visualizations, mostly replacing Honeycomb. We want to have as much control as we can of the apps we need to run Replay. We can tailor these apps to our needs, completely own them and their data, and avoid hostile SaaS vendor behavior like per seat pricing, paywalled features, locking us into their platform, and locking us out from accessing our own data. Today we're launching Builder (https://builder.replay.io/), the tool we used to make these apps, along with the apps themselves and others we've built. You can copy these apps for free, download the source and self host them if you want, or let us take care of hosting, fixing bugs, and modifying them for your needs. If you want to just check these out, here are a couple (shared, no login required) copies of these apps: * Issue tracker: https://16857470-551d-4f50-8e5b-b7d24a4a874a.http.replay.io * Knowledge base: https://d7e0dff4-f45c-4677-9560-6ea739c00a94.http.replay.io We're excited for the power of AI app builders to accelerate the pace of software development, unlock the creativity of non-developers everywhere, and especially to help erode the control that so many large companies have over us. We're continuously building new apps ourselves to help in this endeavor, so let us know what you think! What are the apps and vendors that frustrate you the most?

- JAJig – a tool to define, compute and monitor metrics2021 · jigdev.com · ▲74
Hi HN, 8 months ago, I posted “Ask HN: I built it nobody came, what now?” and got a ton of (not very optimistic) feedback [1]. I took away 3 things: 1. The message wasn’t properly targeted 2. The onboarding experience was terrible. 3. Someone posted some advice to find leads which actually worked, yeah! So here we are. 8 months later. I unfortunately didn’t have a lot of time to put in the tool itself. But I improved the website, improved the onboarding, and got a paying customer who seems to really like the software. So here it is in its current form. Let me know what you think would make…

- APAutomation platform with advanced monitoring and tracing for developers2022 · tunnelhub.io · ▲7
As a long-time developer, I participated in many integration projects and we always had a recurring problem: monitoring and sending integration error alerts to end users. Based on 10 years and hundreds of projects, I created a platform that helps solve this, with several accelerators and cool stuff for developers. Some feedback would be great, if the tool makes sense and what we could improve on.
- B3BugHerd 3 months later2011 · ▲8
Some of you may recall some months ago we started building an app called BugHerd (http://bugherd.com). At the time we had no pricing, no real market strategy and were having a hard time pitching our concept. A lot of people didn't understand why on earth we'd build a bug tracker when there are dozens of great apps out there already...and really, it was a pretty good point! We're now finding that our greatest use case is a communication tool between technical and non-technical users. e.g. stakeholders, clients, managers. BugHerd is now crossing the divide between QA, Feedback and Bug…
- VCVibe coding creates a mess, but it can be solved faster2025 · ▲5
I've been using Cursor, Co-Pilot, ChatGPT, Claude and what not since quite some time now, and we are at a stage where we can just "vibe code" whole apps from idea to execution in a few prompts. I tried this personally to create some side projects that solved little problems for me. But I always got stuck at a point where it just goes into an infinite loop of issues and can't solve the issue by itself. Well I'm a developer, so it's easier for me to dive into the code and solve the problem myself, but that would take a hell lot of time to understand all the code AI wrote for me. If I keep…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
