PocketBase is an open-source backend that comes as a single executable file. It provides a realtime database, user authentication, file storage, and an admin dashboard — all out of the box. You don't need to configure multiple services or write complex server code; just download and run.
Building a backend from scratch is time-consuming and expensive. PocketBase eliminates the need for separate database servers, auth providers, and storage services by bundling everything into one lightweight tool. It's perfect for developers who want a ready-to-use backend without the overhead of traditional cloud services.
PocketBase is ideal for solo developers, startups, and small teams working on web or mobile apps that need a realtime database, user management, and file uploads quickly. It's not for large enterprises requiring advanced multi-region replication, complex permission systems beyond basic roles, or managed scaling — those are better served by cloud-based BaaS platforms.
Use PocketBase to power a realtime chat app, a content management system, a mobile app backend with user logins, or as a rapid prototyping tool. Its JavaScript and Dart SDKs make it easy to integrate with modern frontend frameworks like React, Vue, or Flutter.
