With Lowdefy you can build web apps that AI can generate, humans can review, and teams can maintain. Config that works between code and natural language.

AI writes code fast, but the maintenance doesn't scale. LLMs generate thousands of lines that are hard to review, inconsistent across sessions, and full of hidden vulnerabilities. Lowdefy solves this:

• 50 lines of config vs 500 lines of code — AI generates concise, reviewable config instead of sprawling React components.
• Schema-validated, no arbitrary code paths — Every property validated against a schema. No arbitrary code paths.
• One framework update upgrades all your apps — Config is stable. Lowdefy updates benefits all apps. No fixing each AI-generated codebase individually.
• Config is interpreted, not executed — No code injection possible. Auth, permissions, and data validation built into the runtime.

• Built on Next.js and Auth.js — Deploy anywhere you host Next.js.
• 70+ UI components — Forms, tables, charts, markdown, and more out of the box.
• 50+ logic operators — _if, _get, _js, _state for dynamic UIs without writing code.
• 10+ data connectors — MongoDB, PostgreSQL, MySQL, REST APIs, Google Sheets, S3, Elasticsearch, Stripe.
• Auth & RBAC — 75+ auth providers, public and private pages, role-based access control.

Blocks, Connections, Operators, Actions, Auth Providers, and Adapters can all be extended with plugins. Declare them in config — Lowdefy handles the rest.

Tree-shaking bundles only what you use. Build custom plugins with npm packages and publish them for the community.
