The short version

  • Each has a real cost: Moesif free tier is aimed at hobbyists and small projects, limiting scale before paid usage-based pricing applies.; 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: Moesif covers API traffic monitoring, Zeplo covers URL prefix interface.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Moesif

  • Free tier is aimed at hobbyists and small projects, limiting scale before paid usage-based pricing applies.
  • Usage-based pricing on the Growth tier can make costs less predictable at high event volumes.
  • Requires instrumenting APIs with SDKs, adding setup overhead compared to zero-config tools.
  • Focused specifically on API analytics rather than full API gateway or design functionality.

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.
