Excalidraw

  • Free hosted version persists via scene links/local storage rather than a managed multi-scene workspace
  • Self-hosting the full collaborative stack requires standing up a websocket server and storage beyond the npm editor package
  • No official native desktop or app-store mobile apps - web/PWA only

RAD Studio

  • Professional edition costs $2,000 for the perpetual license plus $599 for year one maintenance, totaling $2,599 before tax
  • Enterprise edition steps up to $3,400 license plus $1,199 maintenance, and Architect edition to $4,416 license plus $2,183 maintenance
  • The perpetual license only entitles the buyer to updates for one year; continued access to new updates and upgrades requires an annually renewable Update Subscription
