About Langflow
Langflow is a visual builder platform for designing, testing, and deploying AI agents and retrieval augmented generation (RAG) pipelines. It lives in the Python based generative AI ecosystem and targets developers building intelligent applications. The project provides a low code interface to assemble components—such as LLMs, vector stores, memory modules, and tools—into executable workflows, while also exposing those workflows as APIs or MCP servers for integration into external applications.

About kubefwd
kubefwd (Kube Forward) is an Apache 2.0 licensed, Go based command line utility that bulk port forwards Kubernetes services to a local workstation, giving each service its own unique 127.x.x.x loopback address and a matching /etc/hosts entry so that locally running code can reach cluster services by their in cluster names, and it is aimed at developers who build and test against a Kubernetes development cluster from their own machine.
