The short version

  • Each has a real cost: Appwrite smaller ecosystem compared to Firebase; fewer third-party integrations and extensions; 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: Appwrite covers REST API, Zeplo covers URL prefix interface.
  • Prices and features above were last checked on 31 August 2026.

  • A team that wants a webhook receiver protected by a concurrency limit so a burst does not overwhelm a downstream APInot Appwrite

Where each one falls short

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

Appwrite

  • Smaller ecosystem compared to Firebase; fewer third-party integrations and extensions
  • Analytics, crash reporting, and A/B testing not included (Firebase includes these)
  • Requires infrastructure management for self-hosted deployments; not fully managed like Firebase Cloud
  • Mobile app support not as mature as Firebase's native iOS/Android SDKs

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.

Answered from the vendors’ own pages

Appwrite: Can Appwrite be self-hosted?

Yes. Appwrite is fully open-source and self-hosted with a single Docker command. Self-hosting is completely free with no feature restrictions, unlike the managed Appwrite Cloud.

Source
Zeplo: How does Zeplo work?

You prefix your endpoint URL with zeplo.to and add query parameters for retries, delay, cron or concurrency. No SDK or broker is needed.

Appwrite: What is Appwrite Cloud's pricing?

Appwrite Cloud offers a free tier with unlimited projects, 75K monthly active users, and 10GB storage with no time limit. Pro plan starts at $15/month per organization member. Scale plan at $599/month includes dedicated resources and SOC 2 compliance.

Source
Zeplo: What does it cost?

Free for 500 requests a month; 39 US dollars a month for a million requests, then 10 dollars per additional million.

Appwrite: What programming languages does Appwrite support?

Appwrite provides SDKs for 15+ languages including JavaScript, Flutter, Swift, Kotlin, Python, Ruby, PHP, .NET, and more, offering more language flexibility than Firebase.

Source
Zeplo: Is it suitable for critical jobs?

It is a small vendor in your execution path with no published SLA below Enterprise, so weigh that against the convenience.

Appwrite: What backend services does Appwrite provide?

Appwrite includes Auth (with multi-factor auth), Databases, Storage (with compression and encryption), Serverless Functions, Messaging, Realtime subscriptions, and Sites (for hosting static and full-stack apps).

Source
Zeplo: Does it work with serverless platforms?

Yes, that is its main use, covering Vercel, Cloudflare Workers, Netlify and similar environments that lack long-running workers.

Appwrite: Does Appwrite include real-time capabilities?

Yes. Appwrite's Realtime service covers all platform services by default through WebSocket subscriptions, enabling real-time updates across databases, functions, and messages.

Source
Appwrite: How does Appwrite compare to Firebase on costs?

Appwrite offers better cost predictability. Firebase's pay-per-read/write model can lead to unexpected bills with runaway queries, while Appwrite's self-hosted model only requires paying for your own infrastructure with completely predictable costs.
