Appwrite replaces Firebase for self-hosted backend needs

Appwrite provides an open-source backend service that includes authentication, databases, storage, functions, and real-time features. Developers deploy this platform using a single Docker command. This setup gives teams control over their infrastructure and data privacy. You should choose Appwrite if you want one SDK-shaped platform or if you need to run the complete application platform on your own servers.

Appwrite vs Firebase comparison

Firebase uses a managed cloud architecture that simplifies maintenance but raises concerns regarding data ownership. Its Blaze plan uses usage-based billing with no spending cap, which can produce unpredictable bills during traffic spikes. A moderately active social app reading 50 documents per session hits costs between $400 and $600 per month on Firestore reads alone. Appwrite allows developers to avoid these costs by hosting the software on their own hardware.

Appwrite Cloud Pro costs $25 per month for the first project and includes 2 TB of bandwidth, 150 GB of storage, and 200,000 monthly active users. Appwrite also supports Dart, Swift, Kotlin, PHP, and Python through official SDKs. This makes it a strong choice for mobile developers who need broad client support. If you use Appwrite to process large lists of events via functions, you must break the import into parts to prevent the function from being killed.

The shift toward SQL and self-hosting

Supabase serves as a popular alternative because it provides a full PostgreSQL database. It uses Row Level Security to enforce permissions at the database layer rather than the SDK layer. This prevents a misconfigured client from bypassing access rules even if an API key leaks. Supabase Pro starts at $25 per month and provides 8 GB of database and 100 GB of file storage.

PocketBase offers a different approach as a single Go binary containing an embedded SQLite database. It idles at tens of megabytes of RAM, whereas a full Supabase stack requires 4 GB to breathe. PocketBase works well for hobby apps or prototypes, but it cannot scale horizontally because it runs on a single node. Users must handle all backups and server security themselves when they use PocketBase.

Appwrite remains a serious contender for teams prioritizing compliance and regulatory requirements. Healthcare and fintech founders often select Appwrite because they want data on infrastructure they own within a specific VPC. This control helps organizations meet strict data residency rules. Does the operational burden of managing twelve containers in a Supabase stack outweigh the benefits of PostgreSQL?

Developers building with Flutter or React Native might find Firebase’s offline sync and push notifications more polished than alternatives. However, Appwrite fits teams that value open-source infrastructure and want to avoid proprietary cloud models. Pick Appwrite when you want to manage your own server and maintain full control over your data.
