Low-Code Platforms
Build internal apps, forms, and workflows with a visual builder and minimal code. Explore open source low-code platforms you can self-host next to your own databases and APIs.
Open Source Projects tagged "Low-Code Platforms"
Windmill
Windmill is an open-source developer platform and workflow engine, and a self-hosted alternative to Retool, Airflow, and Temporal. Scripts written in Python, TypeScript, Go, Bash, or SQL become instant webhooks, scheduled jobs, multi-step flows, or auto-generated UIs. A Rust-based execution engine runs steps across distributed workers for high-throughput job processing.
Budibase
Budibase is an open-source low-code platform for internal tools, and a self-hosted alternative to Retool. You connect an existing SQL database, REST API, or spreadsheet — or use its built-in database — then assemble screens, forms, and automations from prebuilt components. Apps are deployed from the same tool, either to Budibase's own runtime or via Docker and Kubernetes.
