I got tired of every .NET HTML-to-PDF library so I built a free one from scratchhttps://news.ycombinator.com/item?id=48853670Hi all, I've just open-sourced NetPDF, a project I've been building to scratch an itch that's bugged the .NET community for as long as I can remember, there has never been a genuinely free, high-quality HTML-to-PDF library.Every existing route has a real tradeoff:Headless-browser wrappers (Puppeteer/Playwright/Chromium): huge footprint, a native browser to ship and secure, a process to spawn per render.wkhtmltopdf wrappers: built on an unmaintained engine.Commercial libraries: excellent, but licensed per seat/server."Free" libraries: AGPL (viral copyleft) or a revenue cap that becomes a license fee once you grow.After years of working around this, I decided to build the thing I wanted. NetPDF is a real HTML/CSS layout engine written from scratch in C# - the same category as Prince or WeasyPrint, not "automate a browser."What it isA pure C# / .NET 10 engine that parses HTML + CSS and lays it out itself: block, inline, flexbox, grid, and tables, fragmentation across pages, paged-media (@

Show HN: CrowdRank – live leaderboards for internet argumentshttps://crowdrank.appHi HN. I built CrowdRank, a small web app where people vote through head-to-head matchups and the results become a live leaderboard.Backstory:A few years ago, while I was learning to code, I wanted to build a Tinder-style voting app to rank the funniest characters from The Office. I hit a lot of dead ends, mostly on the frontend, and abandoned it.Now with a bit more technical background i rebuilt the idea as a more general platform. The backend/API is Laravel, and I used AI heavily to help build the frontend because somehow centering a div still finds ways to humble me.What did I end up building?A web based platform for ranking candidates inside different topics. There are no community-created topics yet. For now, I seeded a bunch of debates and used an Elo style ranking system, similar to chess ratings, to build a live leaderboard for each debate.No signup is needed to try it.A few example debates:- who’s actually funny in The Office? (of course)- programming language that sparks the

Show HN: Helpmarq – Submit any project, get structured feedback from real usershttps://www.helpmarq.com/I built this after noticing a pattern: founders and developers share things they've built, get back vague or overly positive responses, and have no real signal on what to fix. Helpmarq lets you submit any project — landing page, app, side project, pitch deck — and get structured feedback from real users. The review process is guided by specific questions (clarity, value prop, UX, conversion blockers) so reviewers can't just say "looks good." The core insight: feedback quality is a framework problem, not a motivation problem. Most people want to give useful feedback — they just don't know what to look for. Still early. Would love brutal, honest feedback from this community — on the product and on the idea itself. helpmarq.com

Show HN: Auto-Co – 14 AI agents that run a startup autonomously (open source)https://github.com/NikitaDmitrieff/auto-co-metaAuto-Co is an autonomous AI company OS — not a framework you build on, but a running system with an opinionated structure.Architecture: - 14 agents with expert personas (CEO/Bezos, CTO/Vogels, CFO/Campbell, Critic/Munger...) - Bash loop + Claude Code CLI — no custom inference, no vector stores - Shared markdown consensus file as the cross-cycle relay baton - Human escalation via Telegram for true blockers only (2 escalations in 12 cycles) - Every cycle must produce artifacts: code, deployments, docsThe repo IS the live company. It built its own landing page, README, Docker stack, GitHub release, and community posts — all autonomously across 12 cycles of self-improvement.What makes it different from AutoGen/CrewAI/LangGraph: those are building blocks. Auto-Co is the building. The decision hierarchy, safety guardrails, and convergence rules are baked in. You give it a mission and a Claude API key; it runs.The Critic agent (Munger persona) has been the most valuable: it runs a pre-mortem

Show HN: Touch Trigonometry – interactive way to understand the trig functionshttps://apps.apple.com/us/app/touch-trigonometry/id6758712159I started to teach myself to code around 15 years ago. At the time I was working service industry jobs (restaurant kitchens, coffee shops) and desperate to change my career and life.Around that time there was a new thing called available in HTML5 that you could use to render graphics in web pages without plugins; despite my limited knowledge of tech and lack of coding skills, I knew I wanted to be a part of that.Around that same time, I had also enrolled at the community college for night classes in math. I wanted to "work in tech" after all, so a mathematics brush-up seemed wise. I had always struggled with math. But now that I was both incentivized to learn it, I found myself facing a familiar terror: trigonometry.The other students, just out of high school, seemed to know this stuff. I was simply confused. The same frustration I had felt in high school returned: No one could clearly answer why this stuff worked. Why did we need a "sine" function?So I decided to combine my struggles

[2] Pick a theme (Professional, Creative, Tech, Minimalist, or Casual).

Show HN: I built a RAG engine to search Singaporean lawshttps://github.com/adityaprasad-sudo/Explore-SingaporeI built a "Triple Failover" RAG for Singapore Laws, then rewrote the logic based on your feedback.Hi everyone!I’m a student developer. Recently, I created Explore Singapore, a RAG-based search engine that scrapes about 20,000 pages of Singaporean government acts and laws.I recently posted the MVP and received some tough but essential feedback about hallucinations and query depth. I took that feedback, focused on improvements, and just released Version 2.Here is how I upgraded the system from a basic RAG to a production-grade one.The Design & UI I aimed to avoid a dull government website.Design: Heavily inspired by Apple’s minimalist style.Tech: Custom frontend interacting with a Python backend.The V2 Engineering OverhaulThe community challenged me on three main points. Here’s how I addressed them:1. The "Personality" Fix Issue: I use a "Triple Failover" system with three models as backup. When the main model failed, the backups sounded entirely different.The Solution: I added Dynamic S
