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 herdr
herdr is a terminal first runtime for coding agents — a single Rust binary that owns the terminals in which tools such as Claude Code, Codex, Cursor, OpenCode and Grok run, aimed at developers who keep agents working across local and remote machines and want those sessions to survive a lost SSH connection or a closed client.
