Feature & Specification Comparison

Specification	Zen MCP sh6drack Browser Automation	Manzanas VerifiedBrowser Automation
Summary	Zen Browser automation via WebDriver BiDi. 20 tools for navigation, form filling, screenshots, and JavaScript evaluation. No Selenium or Playwright required.	Drive iOS simulators from Claude Code, Cursor or Codex by accessibility label instead of screenshot-and-tap-coordinates. Exposes ui_tree, tap_element, type_into_element, wait_for_element and scroll_to_element, and every action reports whether the UI actually changed. A Mac daemon underneath hands out simulators as TTL leases with a queue and keeps a SIGSTOP warm pool, so a lease gets a live simulator in about 0.28s instead of a 7s cold boot, and multiple agents can share one Mac without colliding. Open source, MIT.
