Budibase

A low-code platform for assembling internal business apps from a visual builder, connected to your own data rather than to a proprietary database. Apps can be wired to PostgreSQL, MySQL, MSSQL, MongoDB, REST APIs, Docker or Kubernetes targets, and the same workspace handles workflow automations with triggers, branching, loops and email actions.

Operations and IT teams use it to ship request portals, approval flows, dashboards and admin panels without a full engineering project, while developers keep the freedom to extend with scripts and APIs.

Running it yourself keeps business data and automation logic inside your network, avoids per-user pricing on a hosted builder, and lets you back the workspace up with the database tooling you already use.
