The short version

  • Only Whimsical has a free tier, so it costs nothing to try first.
  • Each has a real cost: Whimsical the free plan is capped at 3 team boards, 3 teams and 10 guest seats; 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: Whimsical covers Flowcharts, 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.

Whimsical

  • The free plan is capped at 3 team boards, 3 teams and 10 guest seats
  • File uploads are limited to 5MB per file and 1GB in total on the free plan
  • Version history on the free plan goes back 7 days
  • Voting, the timer, private teams, the GitHub integration, password-protected files and watermark removal all need Pro at $10 per editor per month
  • SSO and SAML are Business tier only at $20 per editor per month

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.
