E2LLM Open Sources SiFR Browser Capture Format
E2LLM has open-sourced SiFR, a deterministic browser capture format that scores page elements by salience and flattens them into a relational model. Unlike DOM dumps or accessibility trees, SiFR produces consistent 5-15 KB captures for LLM consumption. The format is MIT-licensed, while the capture engine remains a hosted product.

The split between open format and closed engine is pragmatic, but the real test is whether developers adopt SiFR over established alternatives like Playwright or Puppeteer.
