Apple silicon Mac (M1 or later), macOS 12 or newer — or Omarchy. There is no Intel, Windows or other Linux build; the editor in your browser runs on all of them.

On Omarchy

Install from the Diagrammo package repository, and it updates with omarchy update like everything else.

bash 
curl -LO https://github.com/diagrammo/dgmo/releases/download/arch-repo/diagrammo-keyring.pkg.tar.zst &&
  sudo pacman -U ./diagrammo-keyring.pkg.tar.zst &&
  sudo pacman -Sy diagrammo

  • You own your files, full stop.

    Plain .dgmo text on your disk, in your folders, under your control. No cloud, no account.

  • Type a line, see the diagram. Instantly.

    A real native macOS app — launches in under a second, redraws as you type, and click any shape to jump straight to the line that drew it.

  • Free. Actually free, not freemium-with-an-asterisk.

    No trial, no license key, no seat count, no upsell modal. Download it, use it forever, and ship it to your whole team without filing a procurement ticket.

  • 50 chart types for the work you actually do.

    Sequence and flowcharts for engineers; org charts, gantt timelines, and kanban boards for managers; sankey, bar, pie, and quadrant for whoever has to make the deck.

  • Open it from your terminal.

    brew install diagrammo/dgmo/dgmo also installs a diagrammo command: diagrammo . opens the current directory, diagrammo foo.dgmo opens a file. See /dev for details.
