- TAThePDFApi, a Chrome Based PDF Generation API Hosted on AWS2018 · ▲41
Hello HN! It kept surprising me how much of a hassle it is to generate a PDF with decent HTML5 rendering from my SaaS apps. I tried several free libs and APIs but ended up with botched rendering a lot of times. So I set out to simplify this chore by creating an AWS hosted HTML to PDF conversion API that's based on Chrome. This API will allow a dev to just send the HTML to our API and get a PDF in response without having to worry about running and managing Chrome somewhere in their infra. I just finished the first version of my landing page and hosted pdf generation API…

Hello everyone, I created a tool called "site2pdf" over the weekend. This tool converts the main page and sub-pages of a website that match a specified URL pattern into a PDF file. It is particularly suitable for AI-based RAG (Retrieval-Augmented Generation) and QA (Question Answering) tasks. GitHub: https://github.com/laiso/site2pdf/ # Features - Generate PDFs of main and sub-pages - Based on Node.js and Puppeteer - Easy-to-use CLI tool I want to make this software available online for my friends, but I'm struggling with the best architecture to use. I want to meet…
- SSScreenCraft – Screenshot and PDF API Without the Puppeteer HeadachesDec 2025 · screencraftapi.com · ▲5
Hey HN, I built a REST API for capturing screenshots and generating PDFs from URLs. Why: I got tired of managing Puppeteer/Playwright in production. Memory leaks, zombie processes, Docker issues. So I wrapped it in an API. Stack: - Node.js + Fastify - Playwright (more stable than Puppeteer in my experience) - Self-hosted on Hetzner Features: - Screenshots: PNG, JPEG, WebP - PDFs: A4, Letter, custom sizes - Full-page capture, custom viewports - Cookie consent auto-accept - Lazy-load handling API example: curl -X POST…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

Built a ~9M param LLM from scratch to understand how they actually work. Vanilla transformer, 60K synthetic conversations, ~130 lines of PyTorch. Trains in 5 min on a free Colab T4. The fish thinks the meaning of life is food. Fork it and swap the personality for your own character.

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
