Endoplexity Runs a Browser Agent Off Your Existing Claude or Cursor CLI Subscription Instead of a Metered API Key

Endokelp/Endoplexity, created 2026-08-14 and already at ~208 stars, is a Chrome side panel that drives your real browser — clicking, typing, filling forms, moving between tabs — by shelling out to the `claude` or `cursor-agent` CLI you already pay for, with no API key and 156 passing tests in its bridge. The framing is the argument: the agent loop is already installed and paid for on your machine; what was missing was hands (a browser it can touch) and a face (a panel that shows the work), so the project ships only the tool server and UI. Because it attaches to your live session, it skips the re-login problem that headless browser agents hit.
