VendorStackWatch: get told when an account adds or drops a tool
VendorStackWatch is a free, read-only check with 8 automated tests: Enter an account's domain for a free tech-stack snapshot from public DNS, SPF and page scripts. On a monitor plan, your named accounts (up to 100 or 500) are re-checked daily, and you see when a tool is added or removed: the switching window your competitors miss. Results are instant; copy-paste fixes and monitoring start at $4.99. It is also available to AI agents as the MCP tool watch_account_tech_stack.
