In plain words

Mini_printf is a lightweight printf() implementation designed for embedded and bare-metal systems. It provides core printf functionality in a self-contained package that requires minimal dependencies, making it suitable for resource-constrained environments where standard library implementations are too heavy or unavailable. The code is available on GitHub and can be integrated directly into projects needing formatted output capabilities.

  • TinyPDF – 3kb pdf library (70x smaller than jsPDF)Dec 2025 · github.com · ▲253

    I needed to generate invoices in a Node.js app. jsPDF is 229KB. I only needed text, rectangles, lines, and JPEG images. So I wrote tinypdf: <400 lines of TypeScript, zero dependencies, 3.3KB minified+gzipped. What it does: - Text (Helvetica, colors, alignment) - Rectangles and lines - JPEG images - Multiple pages, custom sizes What it doesn't do: - Custom fonts, PNG&#x2F;SVG, forms, encryption, HTML-to-PDF That's it. The 95% use case for invoices, receipts, reports, tickets, and labels. GitHub: https:&#x2F;&#x2F;github.com&#x2F;Lulzx&#x2F;tinypdf npm: npm install tinypdf

    Uprintf a universal stb-style printf implementation for C (no OS)2025 · ▲20

    I've been frustrated by the lack of a truly portable, no-dependency printf for embedded and kernel development. Most solutions are either too bloated or missing key features. So I built Uprintf. It's a single-header library that gives you full printf (flags, width, precision, floats, even custom specifiers) from bare metal to desktop, with zero dependencies or #ifdef hell. Key features: · One header file, no dependencies, no dynamic allocation · Full standard support: %d, %x, %f, %.*s, etc. · Extensible with custom format handlers (add %T for your project) · Configurable: disable floats, set…
