Projects.

These projects are already online – each with its own website, most of them with a video too.

DIAGRAMS & MERMAID

selkie io NEW

One diagram. Two forms.

selkie io brings drawing and code together: you draw diagrams on a canvas and edit the Mermaid code at the same time. Change the drawing and the code is rewritten; type code and the drawing follows. If you like, work live on the same diagram with up to six people.

  • Draw flowcharts, class, ER and state diagrams directly
  • Nine themes and a hand-drawn sketch look
  • Collaborate live with up to six people

The app runs on its own website.
