The short version

  • Each has a real cost: Deno Deploy smaller ecosystem compared to AWS Lambda with fewer third-party integrations; 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: Deno Deploy covers Edge Functions, 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.

Deno Deploy

  • Smaller ecosystem compared to AWS Lambda with fewer third-party integrations
  • Less mature than established serverless platforms; newer company and platform
  • 1GB deployment size limit may restrict larger applications
  • 512MB memory limit lower than some competitors for memory-intensive workloads
  • Smaller user base and community compared to Lambda or Netlify

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.
