Show HN: Buoy – A persistent, status-bar web server for local utilities https://ift.tt/bFPilJn

Show HN: Buoy – A persistent, status-bar web server for local utilities I’m constantly building small web-based tools for my own use. Usually, my workflow ends with a dilemma: do I keep a terminal tab open forever running `npx http-server -p 8080`, or do I spend time configuring a Caddyfile for a 50-line HTML tool? Nothing felt right. I wanted something that felt like a native, always-on, utility that was easily accessible but invisible. I built Buoy. It’s a minimal server that: Lives in the status bar: I can see that it's running at a glance without hunting through ps aux. Is persistent by default: It starts with macOS and keeps my utilities alive in the background. Zero-config: It points at a XDG‑Standard www folder so I can create a symlink and be done. Small: I wanted to avoid the modern bloat. Buoy is a single, self-contained binary that's under 10MB. It’s a minimal tool that lets me build many small things and move on to the next. https://ift.tt/sXcPGf2 December 25, 2025 at 09:51PM

Show HN: "What Should I Build?" A directory of what people want Successful entrepreneurs always say that the most profitable tools are the ones that help you solve the issues you’re facing. The problem is, I apparently have no issues. So instead, I built a PoC of a minimalistic ideas directory focused on issues others are facing.

Show HN: Openinary – Self-hosted image processing like Cloudinary https://ift.tt/4uEBfIX

Show HN: Openinary – Self-hosted image processing like Cloudinary Hi HN! I built Openinary because Cloudinary and Uploadcare lock your images and charge per request. Openinary lets you self-host a full image pipeline: transform, optimize, and cache images on your infra; S3, Cloudflare R2, or any S3-compatible storage. It’s the only self-hosted Cloudinary-like tool handling both transformations and delivery with a simple URL API (/t/w_800,h_800,f_avif/sample.jpg). Built with Node.js, Docker-ready. GitHub: https://ift.tt/LKXi5v1 Feedback welcome; especially from Cloudinary users wanting the same UX but on their own infra! https://ift.tt/LKXi5v1 December 23, 2025 at 09:31PM

Show HN: A kids book that introduces authorization and permissions concepts https://ift.tt/fVQhJLH

Show HN: A kids book that introduces authorization and permissions concepts A colleague and I made a kids' picture book that introduces authorization concepts. We work at AuthZed and explain these concepts regularly. We thought it'd be fun to put them together in a format accessible and appealing to kids and grownups alike. It would also be helpful when explaining what we do for work and make a unique gift for our families. The goal was a fun story first and foremost. We aimed to present concepts accessibly but made conscious decisions to simplify, knowing we couldn't be comprehensive in a picture book format. We also wanted visually appealing illustrations, so we built a custom tool to streamline exploring ideas with AI. It does reference-weighted image generation (upload references, weight which ones matter most), git-like branching for asset organization, and feedback loops that improve subsequent generations. It was built with Claude Code. Here's a screenshot: https://ift.tt/LKk0Ntz... We'd love feedback on where we chose to simplify. Did we get the tradeoffs right or did we oversimplify? And lastly, did you enjoy the story? You can read the book online: https://ift.tt/xvZoKCf https://ift.tt/xvZoKCf December 24, 2025 at 12:06AM

Show HN: Meds — High-performance firewall powered by NFQUEUE and Go Hi HN, I'm the author of Meds ( https://ift.tt/xIldsfo ). Meds is a user-space firewall for Linux that uses NFQUEUE to inspect and filter traffic. In the latest v0.7.0 release, I’ve added ASN-based filtering using the Spamhaus DROP list (with IP-to-ASN mapping via IPLocate.io). Key highlights: Zero-lock core, ASN Filtering, Optimized Rate Limiting, TLS Inspection, Built-in Prometheus metrics and Swagger API. Any feedback is very welcome! https://ift.tt/xIldsfo December 22, 2025 at 10:58PM
