Community FAQ
Questions by product
Appwrite FAQ
What are the main challenges when self-hosting Appwrite compared to using managed services?
Self-hosting Appwrite requires managing the entire infrastructure stack including Docker containers, database setup (MariaDB), and SSL configurations. You need to handle backups, scaling, and updates manually, which introduces operational overhead. Unlike managed plans, you won't get automatic scaling or uptime guarantees, so monitoring and maintenance are your responsibility.
Community insight informed by Reddit discussions
Does Appwrite support offline-first or offline data synchronization for mobile apps?
Appwrite does not provide built-in offline-first capabilities or automatic offline data synchronization. While the SDKs support realtime updates when online, you must implement your own local caching and conflict resolution strategies on the client side to handle offline scenarios.
Community insight informed by Hacker News discussions
How does Appwrite ensure full data ownership and privacy when self-hosted?
Since Appwrite is fully open-source and self-hostable, all data remains within your infrastructure. You control the database, storage, and backups, ensuring no third-party has access to your users' data. This setup aligns with strict privacy requirements and compliance needs, unlike proprietary BaaS platforms.
Community insight informed by StackOverflow discussions
Are there any API rate limits or usage restrictions when running Appwrite on-premises?
When self-hosting Appwrite, there are no enforced API rate limits by default; limits depend on your infrastructure capacity. However, managed Appwrite cloud plans may impose rate limits to ensure fair usage. You can implement custom rate limiting proxies or middleware if needed for your self-hosted deployment.
Community insight informed by Forums discussions
What are the recommended migration or export options if we want to move data out of Appwrite?
Appwrite allows exporting your database data via direct database dumps (MariaDB exports) and storage files through standard file system access. There is no built-in one-click migration tool, so you need to handle data transformation and re-import on the target platform manually. The open-source nature facilitates custom scripts for migration.

Supabase FAQ
How complex is it to self-host Supabase for production use?
Self-hosting Supabase involves deploying multiple components including Postgres, the realtime server, auth services, storage, and edge functions. While the core is open-source, production hardening requires configuring backups, scaling, and security measures manually. The official Supabase GitHub repo provides docker-compose setups, but operational overhead is significant compared to managed hosting. Expect to invest in monitoring and maintenance infrastructure.
Community insight informed by Reddit discussions
Does Supabase support offline functionality or local-first data sync?
Supabase does not natively support offline-first or local data sync out of the box. Its realtime features rely on active WebSocket connections to sync data changes. For offline scenarios, developers need to implement client-side caching and conflict resolution manually or integrate with third-party libraries. This makes offline-first app development more complex compared to platforms designed specifically for local sync.
Community insight informed by Hacker News discussions
Who owns the data when using Supabase hosted services? Is there vendor lock-in?
Data stored in Supabase's hosted services remains fully owned by the user, as it is stored in PostgreSQL databases you control. Supabase is open-source, and you can export your data at any time. However, using hosted services means trusting Supabase infrastructure until you migrate or self-host. To avoid vendor lock-in, you can self-host or export your database and storage assets regularly.
Community insight informed by StackOverflow discussions
What are the API limitations when using Supabase's realtime and edge functions?
Supabase realtime APIs support subscriptions to Postgres changes but have limitations on complex query types and large-scale fanouts. Edge functions run in a serverless environment with execution time and resource constraints, which may not suit heavy compute tasks. Additionally, some advanced Postgres features or extensions might not be fully supported in realtime streams or edge functions.
Community insight informed by Forums discussions
How easy is it to migrate existing Postgres databases to Supabase?
Migrating an existing Postgres database to Supabase is straightforward since Supabase uses standard Postgres under the hood. You can dump your current database schema and data and restore it into Supabase. However, you may need to adapt authentication and storage integrations to Supabase's APIs. Also, Supabase-specific features like realtime or edge functions require additional setup post-migration.
