Lowdefy is an open-source, config-first web stack for building secure, maintainable web applications like internal tools, dashboards, and admin panels using simple YAML configurations.

---

🚀 Overview

Lowdefy solves the challenges of deploying AI-generated code to production, such as poor reviewability, inconsistent standards, security vulnerabilities, and breakage from dependency updates. By using declarative YAML configurations that are schema-validated and securely interpreted, it enables rapid development of full-stack apps without the risks of raw code.

It's built for developers, product managers, data scientists, and teams who need to prototype quickly and maintain apps long-term. Whether building internal tools, customer portals, BI dashboards, or workflows, Lowdefy replaces multiple SaaS tools with custom, self-hosted solutions.

We built it to create a bridge between AI-assisted prototyping and human-maintainable production apps—configs that AI can generate, humans can review, and teams can scale confidently.

✨ Key Features

• Config-first development: Define full apps in ~50 lines of YAML vs. thousands of code lines, with schema validation for consistency.
• Secure by design: Interpreted configs prevent code injection; built-in Auth.js with 75+ providers and RBAC for permissions.
• Rich ecosystem: 70+ UI components (forms, tables, charts), 50+ operators (_js, _get), and 10+ connectors (PostgreSQL, MongoDB, Stripe, Google Sheets).
• Extensible: npm plugins for custom blocks, connections, and auth; tree-shaking for optimized bundles.
• Upcoming: Continued plugin ecosystem growth and v4 enhancements.
