Show HN: Guftaguu – Anonymous Chat and Real-Time Games (No Login Required)
I built an anonymous real-time chat app (think modern Omegle) from scratch — plus a bunch of built-in multiplayer mini-games — just because I thought it would be fun.
Try it here: https://guftaguu.vercel.appWhat it does• Anonymous chat:
Instantly pair with a stranger and start talking. No account, no history — everything disappears when you leave.• Play games together:
If the conversation gets awkward (or you just want chaos), you can jump into:Tic-Tac-ToeConnect 4Rock–Paper–ScissorsDo
Ask HN: How can I get better at using AI for programming?
I've been working on a personal project recently, rewriting an old jQuery + Django project into SvelteKit. The main work is translating the UI templates into idiomatic SvelteKit while maintaining the original styling. This includes things like using semantic HTML instead of div-spamming, not wrapping divs in divs in divs, and replacing bootstrap with minimal tailwind. It also includes some logic refactors, to maintain the original functionality but rewritten to avoid years of code debt. Thi

New React RSC Vulnerabilities Enable DoS and Source Code Exposure
The React team has released fixes for two new types of flaws in React Server Components (RSC) that, if successfully exploited, could result in denial-of-service (DoS) or source code exposure.
Goal-Setting App with Community Features
Hey everyone, I'm an alumni who's worked in corporate roles for the past 4 years, and I'm tired of it. I've always wanted to build something that actually helps people, and trusted that if I provide value to society, the money will follow. I have an idea for a startup: before I full send it (i.e., quit my job), I'd appreciate your feedback!About me - I had a relatively smooth university experience: my grades were good enough to apply to most job; I was fortunate to land
Show HN: Pure – An interactive satire on the absurdity of 'Terms of Service'
Hi HN,I built this last week after an experience at a bank branch that stuck with me. The rep literally said, “Don’t bother reading it, just scroll to the bottom so the button unlocks.”It hit me how routine and meaningless “consent” has become, not a decision, just a UI step everyone knows they’re supposed to get through.So I made PURE. It looks like a minimal fintech onboarding flow, but the ToS never actually ends. As you scroll, the text starts reacting to you, poking at the whole idea of bli
Show HN: Manifesto – An AI-Native UI Framework Intent-to-State, Not Text-to-App
Hi HN,I'm the creator of Manifesto AI.I've noticed that while LLMs are getting smarter, their ability to interact with complex Web UIs is still fragile. Agents usually have to "guess" DOM selectors or rely on vision, which leads to hallucinations and broken workflows.I realized that for AI to be useful in SaaS/B2B software, we don't need "Generative UI" (Text-to-App); we need a deterministic "State Layer" that agents can understand and control di
Show HN: Built an all-in-one feedback board for SaaS apps – Ship features
I’ve been building something I personally always needed - a simple, beautiful way to collect product feedback and decide what to build next. Today, it's finally live.Introducing: VicharFlowA minimal yet powerful tool to collect ideas → prioritize them → ship features users loveWhy I built it
Every feedback tool I tried was either too bloated, too expensive, or just boring.
So I made one that focuses on what matters:Everything essential. Nothing extra.

Show HN: Watsn.ai – Scarily accurate lie detector
No signup required—just upload or record a video to verify its truthfulness. You can test it on anyone: internet clips, your significant other, or even yourself.I'm aware there are tons of scammy 'lie detector' apps out there, but I built this using SOTA multimodal models in hopes of creating a genuine breakthrough in the space.It analyzes micro-expressions, voice patterns, and context. In my own testing (over 50 trials), it reached about 85% accuracy, which honestly felt a bit sc
Show HN: Geetanjali – RAG-powered ethical guidance from the Bhagavad Gita
I built a RAG application that retrieves relevant Bhagavad Gita verses for ethical dilemmas and generates structured guidance.The problem: The Gita has 701 verses. Finding applicable wisdom for a specific situation requires either deep familiarity or hours of reading.How it works:
1. User describes their ethical dilemma
2. Query is embedded using sentence-transformers
3. ChromaDB retrieves top-k semantically similar verses
4. LLM generates structured output: 3 options with tradeoffs, implementat
Show HN: GitHired – Find Your Next 10x Engineer
Hey HN - today I’m launching GitHired.
A hiring platform that ranks developers based on what they actually build — not what they claim on a PDF.
It’s called GitHired, and here’s the core idea:
GitHub > ResumesInstead of trusting “proficient in React” bullet points, we analyze a candidate’s actual GitHub:
their real tech stacktheir most complex projectshow active they arewhat kinds of contributions they makewhich skills match your job descriptionand yes, we detect fake “green square farming.”
Show HN: Tusk Drift – Open-source tool for automating API tests
Hey HN, I'm Marcel from Tusk. We’re launching Tusk Drift, an open source tool that generates a full API test suite by recording and replaying live traffic.How it works:1. Records traces from live traffic (what gets captured)2. Replays traces as API tests with mocked responses (how replay works)3. Detects deviations between actual vs. expected output (what you get)Unlike traditional mocking libraries, which require you to manually emulate how dependencies behave, Tusk Drift automatically rec
Show HN: Visual DB – Web front end for your database (update)
Hi HN, I’m Sandhya and we have built Visual DB — a web front end for databases. It lets you create data-entry forms, spreadsheet-like grids, and reports directly on top of your existing relational database.Here’s a quick walkthrough: https://youtu.be/4zv_HQKdKeI (13 minutes)WHAT PROBLEM IS THIS SOLVING?Building CRUD apps with master-detail forms, transactions, and proper concurrency controls typically requires weeks of custom development and ongoing maintenance. Visual DB lets you
Show HN: Pytest-httpdbg – a simple way to include HTTP traces in Allure reports
Hi HN,I recently updated my pytest plugin based on httpdbg to include the HTTP traces directly in the Allure reports. As with httpdbg, the idea is to have nothing more to do than to add an argument to your command line: --httpdbg-allure.For example:pytest examples/pytest_demo.py --alluredir=./allure-results --httpdbg-allureFor each test, all HTTP requests will be recorded and saved in the Allure report under a step named httpdbg.You can check the README in the repository to see how it

Show HN: OgBlocks – Animated UI Library for CSS Haters
Hey HN,I'm Karan, a frontend developer who loves creating UIs, but I've found that many people don't like CSS, but they want their website to look beautiful and polished, and what better way to enhance a website than with animationsAnimations using plain CSS are tricky, and that's why I leaned towards Motion

Show HN: C-Minus Preprocessor v2
About 3 years ago i wrote a custom preprocessor to assist in processing the SQLite project's JavaScript builds (e.g. filtering the small differences between vanilla JS and ESM modules). Recently, that app was forked, refactored into a library, and is now, AFAIK, the world's only source-agnostic[^1], client-extensible preprocessor (if one doesn't count sed, awk, etc.).It's implemented in portable C99 and has a two-file source distribution (one header, one .c file). Its only th
Show HN: ClientDock – Client portal built on Cloudflare Workers
Hi HN,I built ClientDock - a client portal for service providers to manage communications and files without email chaos.Background:
After losing a critical client deliverable in a 200+ email thread, I decided to build a better solution. Most "client portals" are bloated project management tools. I wanted something focused on one thing: making client communication effortless.Technical Details:
- Built with Next.js 15 (App Router)
- Deployed on Cloudflare Workers using OpenNext adapter

Show HN: mDNS name resolution for Docker container names
I always wanted this: an easy way to reach "resolve docker container by name" -- e.g., to reach web servers running in Docker containers on my dev machine. Of course, I could export ports from all these containers, try to keep them out of each others hair on the host, and then use http://localhost:PORT. But why go through all that trouble? These containers already expose their respective ports on their own IP (e.g., 172.24.0.5:8123), so all I need is a convenient way to find
