About.

I'm Massi, the engineer behind webclaw. I build developer tools in Rust and work on web extraction, systems programming, and infrastructure for AI applications.

webclaw started because I needed to get clean content out of web pages for LLM pipelines and every existing tool was either too slow, got blocked, or returned garbage HTML that wasted 95% of tokens. So I wrote my own.

The core extraction engine is Rust, open source, and AGPL-3.0 licensed. It handles TLS fingerprinting at the transport layer (no headless browsers), runs a 9-step content optimization pipeline, and averages 118ms per page for static content. The cloud API adds JavaScript rendering, anti-bot bypass, LLM-powered extraction, and a crawling pipeline on top.

I write about the engineering behind webclaw on the blog. Topics range from token optimization and RAG pipelines to TLS fingerprinting and MCP integration. Everything I publish comes from building and shipping this in production.
