The short version

  • Each has a real cost: Appwrite smaller ecosystem compared to Firebase; fewer third-party integrations and extensions; Doxygen there is no vendor or paid support contract; when something breaks in a large or unusual codebase, the only recourse is community mailing lists, forums or reading the source
  • They diverge on capability: Appwrite covers REST API, Doxygen covers Code comment parsing.
  • Prices and features above were last checked on 1 September 2026.

Doxygen

  • An engineering team generating API reference documentation directly from source code comments as part of a CI buildnot Appwrite
  • A library or SDK maintainer who wants reference docs that cannot drift out of sync with the code because they are generated from itnot Appwrite
  • An internal platform team documenting a large C++ or Java codebase where structure like class hierarchies and call graphs matters more than prosenot Appwrite
  • A project with no documentation budget that still needs professional-looking reference output without any licence costnot 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

Doxygen

  • There is no vendor or paid support contract; when something breaks in a large or unusual codebase, the only recourse is community mailing lists, forums or reading the source
  • Default HTML output looks dated and requires a third-party theme such as Doxygen Awesome to look acceptable to a modern audience, which is extra setup work not included
  • It only generates reference documentation from code comments; it is not a narrative documentation tool, help centre or CCMS, so most teams need a separate tool for guides and tutorials
  • Comment syntax and configuration have a real learning curve, and inconsistent comment discipline across a team produces inconsistent or sparse output regardless of the tool
  • Multi-language support varies in depth; parsing quality for languages outside its C-family core (C++, C, C#, Objective-C) is generally weaker than for its primary targets
  • There is no built-in hosting, search analytics, or reader-facing help centre features, so publishing the generated docs anywhere usable still requires separate infrastructure

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
Doxygen: Is Doxygen really free with no paid tier?

Yes, it is GPL-licensed open source software with no company selling licences or support contracts.

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
Doxygen: Does Doxygen write documentation for me?

No, it extracts and formats documentation from comments a developer has already written in the source code; it does not generate prose from uncommented code.

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
Doxygen: Can it produce anything besides reference documentation?

It can render standalone markdown pages alongside the generated reference content, but it is not a general authoring or publishing platform.

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
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.
