Show HN: Apargon – Ask AI for any app and run it safely with a double-click

Apargon is a macOS and Linux desktop app that runs "papps"—single HTML files with extra <meta> tags—in a sandboxed window with no installer, server, or build step. The sandbox blocks anything the tags don't allow, and a popup shows requested permissions before the page runs; a coding agent can write a papp from one prompt. Install is via a curl script, release downloads, or Homebrew, and Windows is not yet supported.
