The short version

  • Each has a real cost: Sanity free plan limited to 10,000 documents and 100GB assets; Zeplo zeplo sits directly in the execution path of your background work, so an outage at a very small vendor means your jobs do not run at all, and there is no published SLA below Enterprise.
  • They diverge on capability: Sanity covers Content API, Zeplo covers URL prefix interface.
  • Prices and features above were last checked on 31 August 2026.

  • Collaborative content editing with real-time multiplayer supportnot Zeplo
  • API-driven content delivery with GROQ query languagenot Zeplo

Where each one falls short

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

Sanity

  • Free plan limited to 10,000 documents and 100GB assets
  • Free plan supports only public datasets
  • Growth plan capped at 50 seats maximum
  • Private datasets, scheduled drafts, and comments/tasks require paid plans
  • Annual billing unavailable for Growth plan; Enterprise-only

Zeplo

  • Zeplo sits directly in the execution path of your background work, so an outage at a very small vendor means your jobs do not run at all, and there is no published SLA below Enterprise.
  • The free Developer tier includes only 500 requests a month and one team member, so it is a demonstration allowance rather than a usable free plan for anything real.
  • Overage on the Developer tier is 20 US dollars per 100,000 requests, two hundred times the marginal rate on the Company tier, so exceeding the free allowance without upgrading is expensive.
  • Team members cost 15 US dollars each beyond the plan allowance, which is an odd charge on an infrastructure product billed by request volume.
  • Log retention is 30 days on both published tiers, so anything requiring longer audit trails on job execution has to be logged separately.
