Building the config webstack for everyone
Lowdefy is an open-source framework that makes it possible to build web apps using simple YAML or JSON configuration. A higher-order language between code and natural language, designed for both humans and AI.
Our Story
Lowdefy started with a frustration: building internal tools and business apps took too long. Every project needed the same UI components, the same database connections, the same auth setup, but developers kept rebuilding from scratch.
We asked: what if you could describe an entire web application in configuration? Not a drag-and-drop builder with limitations, but a real framework where config handles the 80% and code handles the rest.
Built on Next.js and Auth.js, Lowdefy applications are real web apps, deployable anywhere, version-controlled in Git, and extensible through a plugin ecosystem. The config-first approach also makes Lowdefy uniquely suited for AI-assisted development, where LLMs can generate and review structured configuration naturally.
Today, Lowdefy powers internal tools, admin panels, client portals, and dashboards for teams around the world. And because it's open source, the community helps shape every release.
What We Believe
Open Source First
Lowdefy is Apache 2.0 licensed. We believe the best tools are built in the open, with transparency, community input, and shared ownership.
Simplicity Over Complexity
Config when you can, code when you need to. We aim for the minimum complexity needed to solve real problems.
Built for Everyone
From solo developers to enterprise teams. Lowdefy bridges the gap between no-code simplicity and full-code flexibility.
Ship Fast, Iterate Faster
Internal tools shouldn't take months. Our config-first approach means you can go from idea to production in days.
