Lowdefy

Lowdefy is an open source framework that lets you create web applications by writing YAML configuration files instead of traditional code. It generates a full React single-page application from your config, handling the frontend, backend, and API integrations automatically. This makes it a solid choice for teams that need to ship internal tools quickly without hiring a dedicated frontend team.

The framework supports connecting to databases like MongoDB, PostgreSQL, MySQL, and SQLite, as well as REST and GraphQL APIs. You can define forms, tables, charts, and workflows using a library of prebuilt components. Lowdefy runs on Node.js and can be deployed via Docker, Kubernetes, or any cloud provider. It was created by the Lowdefy team and is licensed under the Apache 2.0 open source license.

Lowdefy is best for developers and IT teams who want to prototype or ship admin panels, dashboards, and data management tools fast. Its configuration-driven approach reduces boilerplate, but you still have the option to write custom JavaScript or React components when needed. The project is actively maintained on GitHub and has a growing community.
