Prompt Board

Excalidraw alternative

Prompt Board vs Excalidraw for boards your team keeps

Excalidraw is the open source whiteboard with the hand-drawn look. You open the editor and draw, with no account, and anyone you send the link to can draw with you. The free editor holds one scene, saved in your browser. Saved scenes, comments and presentations come with Excalidraw+ at $7 per user a month. This page is for teams whose quick sketches have turned into retros, plans and diagrams they want to keep and comment on.

Excalidraw details come from Excalidraw's own pages: the Excalidraw+ pricing page, the home and AI pages, the self-hosting docs, and the README and licence in its GitHub repository. Checked on 2 November 2026. Prices are in US dollars. Check Excalidraw's pricing page before you decide.

Pick Prompt Board if

  • You need more than one board. Prompt Board saves every board to your account with no board limit, where Excalidraw's free editor keeps one scene in your browser
  • You want comments and a slide-by-slide walkthrough without buying seats. Both are free here and part of Excalidraw+ there
  • Your boards are made of sticky notes. The AI sorts them into themed frames and writes a summary, up to 20 times a day per person

Stay with Excalidraw if

  • You want to draw without signing up. Excalidraw opens straight into the editor, and people you invite by link need no account either
  • You need open source. The editor is MIT-licensed, you can host it yourself, and .excalidraw files are open JSON
  • Live sessions must be end-to-end encrypted, or you draw offline
  • You like the hand-drawn look, or you want Mermaid pasted in as shapes and wireframes turned into code

Our take

If you sketch alone or with a few engineers, stay with Excalidraw. It opens without an account, encrypts live sessions end to end and works offline. The MIT licence lets you host the editor yourself, and its AI turns wireframes into code and Mermaid into shapes, which ours does not do.

Prompt Board is for the point where a sketch becomes a team board. Every board saves to your account with no board limit, and comments and presenting frames as slides cost nothing. On Excalidraw, saved scenes, comments and presentations come with Plus at $7 per user a month. In return you sign up to edit, changes reach the others about once a second, and a board holds up to 5,000 objects.
