Spekkio: Reverse-engineer specs from vibe-coded apps
Hey HN, I see vibe-coded apps as basically a working sketch from a domain expert who knows what they want, abdicating responsibility for the "-ilities" (e.g. maintainability, scalability). They're valuable, working, partial specifications - but far from a production-worthy product. Spekkio is an extension of the spec-kit approach that reverse-engineers a vibe-coded app to make best use of what we're given to bridge that gap. Spekkio surfaces the kinds of rubbish that vibe-coded apps accumulate: missing validations, security gaps, inconsistent error handling, dead code, etc... and creates…

What it does
extract value out of a slapp (ai "slop app") through reverse engineering a spec - paulkarayan/spekkio
You have a vibe-coded app. It works (mostly), until it doesn't. But the slapp is still really useful. It's like getting a sketch on a paper napkin with a domain expert who can really articulate what they're looking for - a working example just like the Agile Manifesto promised. Let's watch this play out in the context of spec-kit https://github.com/github/spec-kit Existing code (vibe-coded) ↓ /spekkio.extract ↓ spec.md (inferred user stories, acceptance criteria) features/*.feature (characterization scenarios) ↓ Human review: "Is this what we actually want?" ↓ Adjust spec (remove bugs-as-features, add missing intent) ↓ Normal Spec Kit flow from here how to run it Spekkio is a Claude Code…from github.com

VibeShift MCP2025 · github.com · ▲141Hi HN, We are the devs behind VibeShift. We have been building this MCP server to put AI coding assistants in an automatic feedback loop. They code, test, debug, fix everything until we have a fully working, secure code. It tests like a real user, copies network/console and logical errors to give them back to cursor. (1 min demo - https://www.youtube.com/watch?v=bN_RgQGa8B0) We felt this was the natural next step for AI coding assistants. And with new asynchronous assistants like codex, having a plug & play tester makes sure you don't have to spend time debugging and…
DeVibe2025 · devibe.network · ▲91Hi HN, I noticed that many vibe coders have a problem with building their apps. It's nice and easy when you're starting, but when you need to launch a production-ready app... The fun stops. That's why I built DeVibe: to connect vibe coders with developers. - Vibe coders post jobs; devs apply, and get accepted, or - Devs create services, which vibe coders can book immediately. Goals: make it a go-to place for vibe coders needing help, create more dev jobs in a tough market, and help end users get safer/stable apps. Would love to hear your feedback!
Vibe-check skillJul 2026 · github.com · ▲11Howdy friends. I've been a zero to one product manager for 12 plus years and along the way I kept borrowing pieces from different discovery frameworks until I had a methodology of my own, one that actually raises the odds of an idea succeeding. This does not replace user interviews obviously, but it leads you in the right direction. Looking forward for your feedback

Talanoa▲346Hi 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…
