What is a Self-Hosted Development Platform?

A self-hosted development platform is a set of backend tools and services that you can run on your own infrastructure, such as a server in your office, a virtual private server (VPS) you rent, or a private cloud environment. Unlike traditional Backend-as-a-Service (BaaS) providers, you are responsible for installation, maintenance, and scaling. In return, you get unparalleled data ownership, privacy, and the freedom to customize the platform to your exact needs.

These platforms typically bundle essential backend features like databases, user authentication, file storage, and application programming interfaces (APIs). This allows developers, especially those in small teams or working on personal projects, to build applications faster without building every backend component from scratch. The open-source nature of the platforms listed below means their code is publicly available, fostering community collaboration, ensuring transparency, and preventing vendor lock-in.
