PocketBase
What is PocketBase?
PocketBase is an open-source backend platform that bundles a data store, authentication, file storage, and realtime Application Programming Interface (API) into a single Go binary for building web and mobile applications.
- Embedded backend service with an SQLite-based data store (application backend)
- Built-in user and admin authentication with roles and permissions (identity and access management)
- Realtime subscriptions over WebSocket for data change events (realtime data and messaging)
- Integrated file storage and serving for application assets (object and file storage)
- Single-file Go binary deployable on edge, server, or container environments (deployment and runtime)

More About PocketBase
PocketBase is an open-source backend system implemented in Go that packages core backend services into a single deployable binary, targeting developers who need a self-hosted backend for web, mobile, and desktop applications without assembling multiple independent components.
The platform provides a schema-based data store (application backend) built on SQLite, with collections, fields, and relations definable through an administrative interface and a JSON-based API. This model allows applications to persist structured data while using SQLite’s transactional capabilities, file-based storage, and portability. Developers interact with the data layer through Representational State Transfer (REST) APIs, a JavaScript Software Development Kit (SDK), or other Hypertext Transfer Protocol (HTTP) clients, enabling integration into a variety of frontend frameworks and runtimes.
PocketBase includes a built-in authentication system (identity and access management) that manages users and application-specific records. It supports email- and password-based authentication and additional providers as described in the official documentation. Access rules, per-collection permissions, and admin accounts can be configured through the admin UI, which acts as a control plane for managing data schemas, users, and security configuration.
The project offers realtime capabilities (realtime data and messaging) via WebSocket-based subscriptions. Clients can subscribe to changes on collections, receiving create, update, and delete events in near real time. This capability is used to build collaborative interfaces, dashboards, or reactive user experiences without implementing custom polling or message brokers. The platform also exposes a file storage layer (object and file storage) associated with records, enabling upload, management, and delivery of files such as images or documents through the same backend.
From an operational standpoint, PocketBase is delivered as a single Go binary (deployment and runtime), which embeds the admin UI, API server, and data engine. It runs on common operating systems and can be deployed on virtual machines, containers, or edge environments. Configuration is handled through files and environment variables, and custom logic can be added using Go, allowing teams to extend or embed PocketBase within larger services.
In enterprise or institutional contexts, PocketBase can be positioned as a lightweight Backend-as-a-Service (BaaS) alternative (backend platform) for internal tools, prototypes, line-of-business applications, or edge-deployed systems where a single process with integrated storage, auth, and realtime capabilities is preferable to a multi-service architecture.
