NocoBase

NocoBase is an open-source no-code platform designed for building business applications at speed. It provides a visual interface for designing data models, building forms and tables, creating workflows, and connecting to external APIs. The plugin-based architecture lets teams extend functionality or build custom integrations tailored to their workflow.

It's positioned between spreadsheet-style tools and full low-code frameworks. Small businesses and operations teams use it to replace manual processes and fragmented toolsets; enterprises appreciate the ability to self-host and avoid vendor lock-in. The workflow designer supports complex logic like conditional branches, loops, and multi-step automations without requiring custom code.
