Possible disadvantages of AppWrite

  • Initial Setup Complexity
    The initial setup and configuration can be complex and time-consuming, particularly for those less experienced with server management.

    As compared to some other backend-as-a-service (BaaS) platforms, AppWrite has fewer pre-built third-party integrations, which might limit its extensibility.
  • Newer and Evolving
    AppWrite is relatively new and still evolving, which can mean fewer features compared to more mature platforms and the potential for more bugs.
  • Maintenance Responsibility
    Since it is self-hosted, the responsibility for server maintenance, updates, and security falls solely on the user, which can be a drawback for smaller teams or solo developers.

    Relying heavily on Ablyโ€™s platform-specific features may result in vendor lock-in, making it challenging to switch to other services in the future.
  • Dependence on Internet Connection
    As a cloud-based service, Ablyโ€™s performance is highly dependent on the quality and reliability of the internet connection.
  • Third-party Integration

AppWrite Reviews

  1. Appwrite is awesome, free and open-source!

    I've use it instead of Firebase on a 15$ DigitalOcean droplet and saved around ~$150 a month. Managing my own infra does take some extra time, but definitely worth it. The APIs and SDK are also surprisingly much easier to consume than Firebase. Waiting for the cloud version.
