🛠️ Saccade – Live semantic browser truth for AI agents
Summary
Saccade is a browser extension and local Node.js broker that compiles open browser tabs into semantically meaningful objects for AI agents. It uses MCP to let agents read page states and execute actions quickly using stable object IDs.
Why it’s interesting
It achieves millisecond reaction loops and performance close to Playwright by streaming page changes as deltas after an initial full read.
