Introduction
Building modern applications requires much more than creating a user interface. Developers need databases, authentication systems, file storage, APIs, real-time updates, and backend logic. Traditionally, setting up and maintaining this infrastructure required significant time and operational effort.
Backend-as-a-Service (BaaS) platforms simplify this process by providing ready-to-use backend capabilities. Instead of building everything from scratch, developers can focus on creating features and delivering value to users.
Among the growing number of backend platforms, PocketBase and Supabase have gained significant attention in the open-source community. Both aim to accelerate application development, but they take very different approaches to solving backend challenges.
PocketBase focuses on simplicity, portability, and minimal infrastructure requirements. Supabase emphasizes scalability, PostgreSQL-powered features, and enterprise-grade capabilities.
In this article, we'll compare PocketBase and Supabase, examine their architectures, strengths, limitations, and help you decide which platform best fits your project.
