Langflow preinstalled for AWS. The open source low-code visual builder for AI agents and RAG applications, on Python 3.12 and Ubuntu 24.04, with login required and a per instance admin password generated on first boot. Backed by 24/7 cloudimg support.
## Langflow by cloudimg
Langflow is the popular open source, low-code visual builder for AI agents, chatbots and retrieval augmented generation (RAG) applications. You design flows by dragging and connecting components on a canvas, then run and serve them through a built in API. This Amazon Machine Image delivers Langflow fully installed and configured, so a production ready AI agent builder is running within minutes of launch. The release available is Langflow 1.9.
## Application Stack
Langflow is installed into a dedicated Python virtual environment on Python 3.12, runs as an unprivileged service user on the loopback address, and is fronted by an nginx reverse proxy on port 80 with the WebSocket and streaming support Langflow needs. A systemd unit starts it on boot.
## Secure First Boot
Langflow ships with authentication disabled out of the box. This image instead requires login and creates a single administrator account whose password, and the key that encrypts the credentials you store in your flows, are generated uniquely for every instance on first boot and written to a root only file. No shared or default credentials ship in the image.
## Ready To Use
Sign in on port 80 and connect Langflow to any language model endpoint you choose, including OpenAI, Anthropic, Amazon Bedrock or a self hosted model, plus your vector store. Flows, the database and the encryption key live on a dedicated, resizable volume. Because Langflow calls out to an external model endpoint, the image is CPU only and ships no model weights.
## cloudimg Support
cloudimg provides 24/7 technical support for this image, covering Langflow deployment, connecting model and vector store providers, building agent and RAG flows, serving them through the API, TLS termination and scaling.
