Good effort! Did you consider using Netsurf codebase ( https://www.netsurf-browser.org/ ) or contributing to it? (The website is outdated but the development is ongoing and active).
Nordstjernen is a ~30 kLOC solo-built C browser aimed at being a small, hardened web reader for the text-heavy web, while Ladybird is a ~500 kLOC funded C++ project aiming to be a fully standards-compliant third browser engine alongside Blink, WebKit, and Gecko.
Nordstjernen is a small, sandboxed, JIT-free GTK browser for humans to read the web; Lightpanda is a Zig-based headless V8 browser for AI agents to script it.
Are you asking the author to validate your own opinion? Why don't you explain why you think its slop and provide some evidence to back up your assertions and we can have a real discussion.
slop is such a poorly defined term that it's very hard to answer your question meaningfully. Is all code generated by AI slop? Many different opinions on this and questions to be answered as LLMs continue to shift the programming landscape.
