Open Source Frameworks & Platforms Software
Frameworks & Platforms software provide the underlying infrastructure and visual interfaces needed to build applications without starting from scratch. These tools automate backend tasks like database management, authentication, and API generation to speed up the development cycle. This type of software serves developers and creators who need to deploy custom workflows or internal tools. Self-hosting these apps ensures that sensitive database records and application logic remain on private servers rather than on external cloud platforms.
This page lists 62 open source tools in the Frameworks & Platforms category. The most popular are n8n, Dify and Open Design. Most use the MIT or Apache-2.0 license, and 51 offer an official Docker image.
