What Diagraw is

Diagraw is a browser-based collaborative whiteboard and diagram editor with an infinite canvas. People can join live sessions through a link without an account, then collaborate using live cursors, presence indicators, and comments. The editor imports and exports Mermaid diagrams and Miro boards, and exports diagrams as PNG, SVG, or PDF. Its Lyra assistant turns plain-language descriptions into editable diagrams, with usage limits on the free tier. Diagraw provides 726 official AWS, Google Cloud, and IBM Cloud service icons; five icons per cloud are free, while Pro includes the full set. The free plan costs nothing and allows 25 saved diagrams, 10 automatic versions per diagram, 3 MB per diagram, shared sessions for seven days, and five Lyra requests every three hours. Diagraw Pro costs €6 a month, billed at 60 €/year, and adds unlimited diagrams, permanent shared links, longer interviews, and more observers. Data is hosted in the European Union.
