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 Palform
Palform is an open source form builder built around end to end encryption, released under the AGPL 3.0 license. It is written primarily in Rust and JavaScript, and it lives in the Rust ecosystem: the backend uses the Rocket web framework with SeaORM, while encryption and shared logic are compiled to WebAssembly so that the same code runs in the browser and on the server. The entire codebase is open source, including the marketing pages, and this repository is stated to contain everything needed to operate the service. A free hosted instance runs at palform.app on European hosted servers.
