Single-File Backend
A backend architecture pattern where the entire application logic, database, and API are encapsulated within a single executable binary or file. This approach minimizes deployment complexity, reduces infrastructure overhead, and offers a lightweight alternative to traditional cloud-native stacks.
Key Characteristics
- Portability: Runs on any standard OS without complex dependency chains.
- Cost Efficiency: Eliminates vendor lock-in and reduces cloud hosting costs compared to managed services.
- Simplicity: Simplifies CD pipelines and local development environments.

PocketBase: Single-File Backend Mitigating Firebase Cost Overruns
PocketBase is a prominent open-source backend solution that embodies the single-file backend philosophy. It serves as a direct alternative to Firebase and other managed backend-as-a-service (BaaS) providers.
- Architecture: Delivers a full backend (database, auth, API, admin UI) in a single Go binary.
- Cost Mitigation: Specifically addresses Firebase cost overruns by allowing self-hosting on inexpensive VPS instances.
- Use Case: Ideal for developers seeking a Firebase replacement without the operational complexity of managing multiple microservices.
