- For
- Mac users building small apps with coding agents
- Worth noticing
- Each app is a .plppx folder; its separate data directory includes a kv.sqlite file, and app deletion sends both to Trash.
Field notes
The documented workflow starts with an agent creating a .plppx bundle, then uses Plopp's CLI to validate and add it to a library. The page describes per-app SQLite storage, permissioned file areas, and separate tabs; it also shows a Tailscale-based route for opening apps from another Mac. The homepage lists Claude Code, Codex, Gemini CLI, Cursor, and other agents that read Agent Skills as compatible.
