The browser engine for agents. HTML in, Semantic Object Model out. 10x token compression, V8 JS rendering, CDP compatible. Apache-2.0.

Plasmate compiles HTML into a Semantic Object Model (SOM), a structured representation that LLMs can reason about directly. It runs JavaScript via V8, supports Puppeteer via CDP, and produces output that is 10-800x smaller than raw HTML. It is purpose-built for AI agent pipelines, with MCP, Vercel AI SDK integrations, and over 60 ecosystem integrations.

    The browser engine abstraction handles the rendering complexity so agents focus on content.

    Good for AI agents that need to understand web pages without consuming huge context.

    HTML to Semantic Object Model with 10x token compression is a compelling efficiency gain.

    Token compression matters a lot when processing many pages in one workflow.
