Built for modern Macs.

Deckosaurus runs on macOS 14 Sonoma or newer. Apple Silicon (M1/M2/M3/M4) is recommended — the on-device oMLX models lean on the Neural Engine and unified memory for fast tokens. Intel Macs are supported and will run every feature; they'll be slower on local inference. The current release (v0.2.280) is a 30–35 MB DMG; the installed app sits at ~150 MB after Round Rect's strip pass.

Verify the download.

Confirm the DMG hasn't been tampered with by comparing the SHA-256 against the value on the GitHub release page. Treat the result as table-stakes for any tool that gets to read your code.

First launch, in 30 seconds.

  • A welcome window with one Sample workspace pre-wired so you can poke around without picking a folder.
  • The deck CLI installed to ~/Library/Application Support/Codeck/bin/ and added to PATH for new shells.
  • A built-in oMLX agent ready to chat, with no API key required.
  • Apple Intelligence integration weak-linked for macOS 26+ — lights up automatically on supported builds, invisible otherwise.
  • A telemetry opt-in prompt that's genuinely opt-in — no boxes pre-ticked.
