The short version

  • Each has a real cost: Appwrite smaller ecosystem compared to Firebase; fewer third-party integrations and extensions; Maestro cloud pricing is per concurrent device at 250 USD per month, so the cost is driven by how quickly you need the suite to finish rather than by how much you test, and a team wanting a fast pull request gate buys several devices at once.
  • They diverge on capability: Appwrite covers REST API, Maestro covers YAML test flows.
  • Prices and features above were last checked on 30 August 2026.

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

Maestro

  • Cloud pricing is per concurrent device at 250 USD per month, so the cost is driven by how quickly you need the suite to finish rather than by how much you test, and a team wanting a fast pull request gate buys several devices at once.
  • YAML is deliberately limited, so tests with real conditional logic or data-driven permutations end up in embedded scripting blocks where the readability advantage that justified the format disappears.
  • Maestro drives the app as a black box, so it cannot assert on internal state, mock a network layer from inside the process or inspect application memory the way an in-process framework can.
  • The hosted device catalogue is narrower than dedicated device clouds, so testing against a long tail of specific manufacturer builds and older operating system versions still requires another provider.
  • The project rebranded from mobile.dev to Maestro, so a share of existing tutorials, blog posts and links point at old domains and documentation that no longer match the current tooling.

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
Maestro: Is Maestro free?

The CLI, Studio and local execution are free and open source. The hosted device cloud is 250 USD per device per month.

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
Maestro: What exactly does per device mean?

It is a concurrency slot. One device runs one test at a time, so suite duration is a function of how many devices you buy.

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
Maestro: How does it compare with Appium?

Tests are YAML rather than code and flakiness handling is built in, which reduces maintenance, at the cost of lower-level control.

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
Maestro: Can it test web applications too?

Yes, the cloud offers hosted web devices alongside Android and iOS, though the product centre of gravity is mobile.

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.
