Overview
This is a repackaged software product wherein additional charges apply for hardening, security configuration, and support.
WHAT IS LANGFLOW
Langflow is a visual drag-and-drop builder for LLM-powered applications - a Python (FastAPI) and TypeScript (React) stack that lets developers compose chains, agents, and retrieval-augmented generation (RAG) pipelines from pre-built components on a canvas, then deploy them as REST endpoints. It integrates with 100+ LLM providers and vector stores (OpenAI, Anthropic, AWS Bedrock, Azure OpenAI, Ollama, Qdrant, Chroma, Pinecone) through the underlying LangChain abstractions, plus tool nodes for web search, SQL and file I/O. Persists flows, conversations and configuration in PostgreSQL. MIT license - lock-in-free alternative to LangSmith and other proprietary visual AI builders, with full Python source for every component.
WHAT THIS AMI ADDS
Security hardening:
- Authentication enabled - LANGFLOW_AUTO_LOGIN=False
- Admin password equals EC2 Instance ID
- Nginx reverse proxy with TLS - Langflow bound to localhost only
- UFW firewall - ports 22, 80, 443 only
- fail2ban, AppArmor
OS hardening (CIS Level 1):
- CIS Ubuntu 24.04 LTS Level 1 benchmark applied via ansible-lockdown
- auditd, SSH hardening, Kernel hardening, IMDSv2 enforced
Compliance artifacts:
- SBOM - CycloneDX 1.6 at /etc/lynxroute/sbom.json
- CIS Conformance Report at /etc/lynxroute/cis-report.html
- CIS Tailored Profile at /usr/share/doc/lynxroute/CIS_TAILORED_PROFILE.md
Highlights
- Langflow secure by default: authentication enabled, Nginx TLS reverse proxy, admin credentials unique per instance - no open access out of the box.
- CIS Level 1 hardened Ubuntu 24.04 LTS: auditd, fail2ban, AppArmor, SSH key-only, IMDSv2 enforced. CVE-scanned before every release. SBOM (CycloneDX) and CIS Conformance Report included.
- Visual AI workflow builder: drag-and-drop interface for RAG pipelines, multi-agent flows, and LLM automation with 100+ integrations - no OpenAI/Anthropic subscription costs at scale.

64-bit (x86) Amazon Machine Image (AMI)
Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
Version release notes
Updated to version 1.9.1.
Additional details
Usage instructions
- Launch instance (t3.medium required)
- Open Security Group - allow TCP 443 and TCP 80 from your IP
- Wait 1-2 minutes after instance start for Langflow to initialise
- SSH: ssh -i key.pem ubuntu@<PUBLIC_IP>
- Read credentials: sudo cat /root/langflow-credentials.txt
- Open https://<PUBLIC_IP> - accept the self-signed certificate warning
- Log in with admin credentials from the credentials file
Admin password equals the EC2 Instance ID. Credentials are saved to /root/langflow-credentials.txt at first boot. Replace the self-signed TLS certificate with a CA-signed certificate for production use.
