About

AppPlatform has a Java backend built on the FIT framework and a React frontend for creating, debugging, running and publishing AI applications. The visual flow editor is built on the Elsa graph engine, and a Store holds reusable apps that appear as tools for agents. The README notes that the open-source deployment has no built-in authentication for plugin uploads, so operators must add their own protection.

Use cases: agent-orchestration, workflow-automation

Done for you

Rather not set it up yourself?
