The short version

  • Only Excalidraw has a free tier, so it costs nothing to try first.
  • Each has a real cost: Excalidraw advanced features (unlimited private scenes/folders, cloud storage, access management, presentations, extended AI, team management) are gated behind Excalidraw+; Zeta it competes against card processors with decades of production track record, and in card processing an outage is a public event, so a shorter operational history is a genuine risk factor rather than a technicality.
  • They diverge on capability: Excalidraw covers Hand-drawn style diagrams, Zeta covers Tachyon card processing.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Excalidraw

  • Advanced features (unlimited private scenes/folders, cloud storage, access management, presentations, extended AI, team management) are gated behind 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

Zeta

  • It competes against card processors with decades of production track record, and in card processing an outage is a public event, so a shorter operational history is a genuine risk factor rather than a technicality.
  • Contracts are enterprise scale and quoted with volume minimums, which puts it out of reach of small issuers who would otherwise benefit most from modern tooling.
  • A card portfolio migration runs twelve to twenty four months at minimum, during which the issuer runs two platforms and pays for both.
  • Zeta is a processor rather than a licence holder, so network membership, BIN sponsorship and regulatory obligations remain entirely with the issuer.
  • Public references for large live United States production volumes are fewer than the announcements imply, so diligence should insist on active account counts and uptime history rather than partnership press releases.
