PlutoPrint – Generate PDFs and PNGs from HTML with Python▲161
Hi everyone, I built PlutoPrint because I needed a simple way to generate beautiful PDFs and images directly from HTML with Python. Most of the tools I tried felt heavy, tricky to set up, or produced results that didn’t look great, so I wanted something lightweight, modern, and fast. PlutoPrint is built on top of PlutoBook’s rendering engine, which is designed for paged media, and then wrapped with a Python API that makes it easy to turn HTML or XML into crisp PDFs and PNGs. I’ve used it for things like invoices, reports, tickets, and even snapshots, and it can also integrate with Matplotlib…

Header-only GIF decoder in pure C – no malloc, easy to use▲47
I built a lightweight GIF decoder in pure C, ideal for embedded or performance-critical environments. It’s header-only, zero dynamic memory allocations, and fully platform-independent. Supports both static and animated GIFs, with turbo and safe decoding modes. Works great on microcontrollers, IoT devices, and anything with a framebuffer. Would love feedback or ideas where this could be useful. Github: https://github.com/Ferki-git-creator/TurboStitchGIF-HeaderOn...

Purl – A Simple Tool for Text Processing▲71
Hello HN community, I'm excited to share a new command-line tool I developed called purl, inspired by the simplicity of Perl one-liners for efficient text processing. Purl features include Perl-like regex that simplifies text manipulation, it's cross-platform so works equally well on macOS, Linux, etc., and it's quick and easy to install. The tool also supports simple commands such as -replace, -filter, and -exclude, and offers optional color output to enhance readability. Purl is a practical alternative to traditional tools like sed and grep, designed to address some of their common…

Minimal – Open-Source Community driven Hardened Container Images▲120
I would like to share Minimal - Its a open source collection of hardened container images build using Apko, Melange and Wolfi packages. The images are build daily, checked for updates and resolved as soon as fix is available in upstream source and Wolfi package. It utilizes the power of available open source solutions and contains commercially available images for free. Minimal demonstrates that it is possible to build and maintain hardened container images by ourselves. Minimal will add more images support, and goal is to be community driven to add images as required and fully customizable.
