Try Clew

Clew adds product tours, tooltips, popups, onboarding checklists and two-step rating popups to your web app. Paste one script once, then build on your live UI in a visual editor. Target by page, trigger and user properties; A/B test any tour and see if the lift is significant before making B the main version. Health checks flag steps whose element is gone. On Pro, an MCP server lets Claude, Cursor or Codex build tours for you. EU cloud or self-hosted, free plan.
