Show HN: A Prompt-Injection Firewall for AI Agents and RAG Pipelines We built SafeBrowse — an open-source prompt-injection firewall for AI systems. Instead of relying on better prompts, SafeBrowse enforces a hard security boundary between untrusted web content and LLMs. It blocks hidden instructions, policy violations, and poisoned data before the AI ever sees it. Features: • Prompt injection detection (50+ patterns) • Policy engine (login/payment blocking) • Fail-closed by design • Audit logs & request IDs • Python SDK (sync + async) • RA…

Show HN: Client-side encrypted AI detector using model ensembling Hi HN, I’m Oscar, a Year 8 student from Australia who enjoys messing around with computers and AI. I recently built an AI detector to build on my skills in computer science. I entered the prototype into the Oliphant Science Awards which is a local science competition (writing a 4000-word report on the methodology) and ended up winning, so I decided to polish it into a real web service that the world can make use of. I noticed that schools and businesses are rushing to use AI det…

Show HN: A dynamic key-value IP allowlist for Nginx I am currently working on a larger project that needs a short-lived HTTP "auth" based on a separate, out-of-band authentication process. Since every allowed IP only needs to be allowed for a few minutes at a time on specific server names, I created this project to solve that. It should work with any Redis-compatible database. For the docker-compose example, I used valkey. This is mostly useful if you have multiple domains that you want to control access to. If you want to allow 1.1.…

Specifically, I wanted to figure out what my text conversations say about my relationships and myself, and if there’s been evolution throughout the year. Who reaches out more? What’s our tone and conflict resolution? What were our month by month successes and conflicts? So I …

Show HN: Pion SCTP with RACK is 70% faster with 30% less latency SCTP is a low level protocol focused on reliable packet transmission.

Going into an established library, I thought that everything was already implemented and that there wasn't anything to do until I went through the existing issues and organized all the tasks and decided on an order.

Show HN: I replaced my premium workout app with vibecode https://ift.tt/7yQsIG8
Show HN: I replaced my premium workout app with vibecode I was going through my app subscriptions and realized I was paying $15 for a pretty good workout app, which seemed a bit high to me. As a software engineer who is also well versed in claude code, I realized that I could likely vibecode a very similar app, or even build something more to my liking. I challenged my self to build something roughly equivalent this afternoon. Workflow was: start with a detailed spec from Claude code describing many of the features common in workout apps. Then…
Show HN : WealthYogi - Net worth Tracker https://ift.tt/j3F1lpt
Show HN : WealthYogi - Net worth Tracker Hey everyone I’ve been on my FIRE journey for a while and got tired of juggling spreadsheets, brokers, and bank apps — so I built WealthYogi, a privacy-first net worth tracker focused on clarity and peace of mind. Why Like many FIRE folks, I was juggling spreadsheets, bank apps, and broker dashboards — but never had one clear, connected view of my true net worth. Most apps required logins or shared data with third parties — not ideal if you care about privacy. So I built WealthYogi to be: Offline-first …
Show HN: OpenFret – Guitar inventory, AI practice, and a note-detection RPG https://ift.tt/ewkZ7c9
Show HN: OpenFret – Guitar inventory, AI practice, and a note-detection RPG I'm a solo dev and guitarist who got frustrated juggling separate apps for tracking gear, practicing, and collaborating. So I built OpenFret—one platform that handles all of it. What it does: 1) Smart inventory – Add your guitars, get auto-filled specs from ~1,000 models in the database. Track woods, pickups, tunings, string changes, photos. 2) AI practice sessions – Generate personalized tabs and lessons based on your practice history. Rendered with VexFlow notati…
Show HN: Watsn.ai – Scarily accurate lie detector https://ift.tt/3cPolat
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: Radioactive Pooping Knights https://ift.tt/CjHoRiS
Show HN: Radioactive Pooping Knights I've been having fun building out a really simple chess learning app for my daughter (7). It started with just "maze like" puzzles [1] and I've added a few more. This "radioactive pooping knights" idea came from an Irish primary school chess website [2]. Really simple idea, two knights moving around the board leaving poo behind... Don't be the one forced to step on it. * best played with sound on. [1]. https://ift.tt/7M9aBp6 [2]. https://ficheall.ie/ *highly subjective, may n…

Show HN: I built a dashboard to compare mortgage rates across 120 credit unions https://ift.tt/lxQZEVT
Show HN: I built a dashboard to compare mortgage rates across 120 credit unions When I bought my home, the big bank I'd been using for years quoted me 7% APR. A local credit union was offering 5.5% for the exact same mortgage. I was surprised until I learned that mortgages are basically standardized products – the government buys almost all of them (see Bits About Money: https://ift.tt/kMjAEqK... ). So what's the price difference paying for? A recent Bloomberg Odd Lots episode makes the case that it's largely advertising and market…

Show HN: Docmd v0.3 – Static documentation generator (built-in search, no React) Hi HN, I posted docmd here a few months ago when it was just a simple markdown parser. I'm back with v0.3 because we just hit a major milestone: fully offline, client-side full-text search with zero configuration. I built this because I wanted a Node.js-native alternative to MkDocs Material. I didn't want to install Python in my CI/CD just for docs, and Docusaurus felt too heavy (React hydration) for simple static text. Docmd generates raw HTML/CSS, is und…

Show HN: NeurIPS 2025 Poster Navigator I woke up Sunday morning ready to schedule my week at NeurIPS. To my immediate horror, the NeurIPS.cc poster sessions have 1k+ posters in a stupid little dropdown. So I built a little app to help navigate them by research area/keywords/etc. Built it in a few hours with codex, gemini-cli, and Claude code. Same stack that produced 50% of the papers at NeurIPS ;) Free to use, no signup. https://ift.tt/drPOD1s December 2, 2025 at 04:55AM
