Appsmith

Deploy Appsmith on Out Plane — an open-source low-code platform for building internal tools, admin panels, and dashboards. Appsmith provides a drag-and-drop UI builder with 45+ pre-built widgets, connects to 25+ databases and any REST or GraphQL API, and lets you write custom JavaScript logic for complex workflows. It is a self-hosted alternative to Retool.

Appsmith supports direct connections to PostgreSQL, MySQL, MongoDB, Elasticsearch, Redis, S3, and more. Build CRUD interfaces, approval workflows, customer support dashboards, and admin panels in hours instead of weeks. Self-hosting on Out Plane gives you unlimited apps and users without per-seat licensing.

Ideal for engineering teams building internal tools, customer support dashboards, data management interfaces, and any admin panel that would otherwise require custom full-stack development.
