Our take

Made by Together AI, MIT licensed, with a large star count and recent activity. It ships twenty-one themes, a Custom mode, and fifty-seven slop-test gates, exposed through four verbs (default build, audit, redesign, study). Output is self-contained HTML and CSS, and manual install is supported by copying SKILL.md and references into Claude Code, Cursor, or Codex skill directories.
