Langflow

Langflow is a powerful platform for building and deploying AI-powered agents and workflows. It provides developers with both a visual authoring experience and built-in API and MCP servers that turn every workflow into a tool that can be integrated into applications built on any framework or stack. Langflow comes with batteries included and supports all major LLMs, vector databases, and a growing library of AI tools.

Verify that it is working

Open https://www.example.com in your browser. You should see the Langflow interface and be able to continue using Langflow through OpenLiteSpeed over HTTPS.

Disable public access to port 7860 after confirming everything works.
