About Lowdefy

Lowdefy is an open-source framework for building web apps from configuration files rather than code. Its pitch is that concise, schema-validated config is easier for both people and AI tools to generate, review, and maintain than thousands of lines of generated React. It is released under the Apache-2.0 license.

Apps are described in YAML, and the runtime interprets the config instead of executing arbitrary code, with authentication, permissions, and data validation built in. The framework includes over 70 UI components such as forms, tables, charts, and markdown, more than 50 logic operators for dynamic behavior, and over 10 data connectors including MongoDB, PostgreSQL, MySQL, REST APIs, Google Sheets, and S3.

It is built on Hono, Vite, and Auth.js and can be deployed anywhere Node.js runs. A framework update upgrades every app at once, which the authors present as a maintenance benefit. It suits teams building CRUD apps, admin panels, dashboards, and workflow tools who want something between a low-code platform and a custom codebase.
