TweakThis vs Pastel
Both tools let clients point at an element on a live website and let Claude Code or Codex work on it over MCP. Pastel loads the site on a shareable canvas, so reviewers need no account or extension; TweakThis is a browser extension built around the loop from a client’s note to an agent’s fix and the client’s sign-off.
