Plasmate is a headless browser engine built in Rust that compiles HTML into a Semantic Object Model (SOM), a structured representation optimized for LLM reasoning. It's innovative because it's purpose-built for AI agents with native MCP support, offers 10-800x token compression over raw HTML, and provides Puppeteer compatibility while being significantly faster and lighter than alternatives.

Target audience: backend devs, devops, data engineers, ai engineers
