Lowdefy

Lowdefy is a config-based web framework for building business web applications such as internal tools, admin panels, dashboards, CRUD apps, and client portals. Apps are defined primarily in YAML or JSON and run as a Next.js application, with extensibility through plugins when custom code is needed.

Key Features

• Build multi-page web UIs using a library of reusable UI building blocks
• Declarative logic, state, and UI behavior using built-in operators and actions
• Connect to external databases and APIs via configurable requests (no built-in data store)
• Extensible architecture with npm plugins for custom blocks, actions, operators, requests, and auth adapters/providers
• Authentication and authorization support via Auth.js integration, including role-based access control
• Deployable wherever Next.js runs, including containerized deployments

Use Cases

• Internal admin tools for managing operational data and workflows
• Client portals with authenticated access and role-based permissions
• Business dashboards and CRUD-style applications backed by existing APIs and databases

Limitations and Considerations

• Data persistence is provided only through external systems (databases/APIs), so you must configure and operate those separately

Lowdefy fits teams that want to deliver business apps quickly with mostly configuration, while still allowing custom React/JavaScript extensions. It is well-suited to organizations standardizing internal tooling on a repeatable, version-controlled configuration approach.
