FixBrowser – a lightweight web browser created from scratch▲320
Hello, I'm working on a web browser that focuses on being truly lightweight and designed for privacy. At some point I've realized that much of the complexity and resource requirements of web browsers comes from JavaScript. This is because every part needs to be dynamic and optimized for speed. So a few years ago I've started to work on a web browser that intentionally doesn't implement JavaScript, instead it contains an updated set of scripts that fix and improve various websites.

Shibuya – A High-Performance WAF in Rust with eBPF and ML Engine▲22
Hi HN, I’ve been working on Shibuya, a next-generation Web Application Firewall (WAF) built from the ground up in Rust.

What makes Shibuya different: Multi-Layer Pipeline: It integrates a high-performance proxy (built on Pingora) with rate limiting, bot detection, and threat intelligence. eBPF Kernel Filtering: For volumetric attacks, Shibuya can drop malicious packets at the kernel level using XDP before they consume userspace resources.…
