This product has charges associated with it for hardening, security configuration, and support.
Langflow is an open-source visual framework for building multi-agent and RAG AI applications. This Lynxroute build is security baked in: authentication enabled, Nginx TLS reverse proxy, unique admin credentials at first boot, and CIS Level 1 hardened Ubuntu 24.04 LTS base.
Note: Langflow initialises in ~60 seconds after instance start. Wait 1-2 minutes before opening the Web UI.
MIT license - fully auditable, no vendor lock-in.
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.

Dimension | Cost/hour |
|---|---|
t3.medium Recommended | $0.05 |
m6i.2xlarge | $0.05 |
m6i.large | $0.05 |
m6i.xlarge | $0.05 |
t3.large | $0.05 |
Dimensions summary
You pay by the hour for the EC2 instance size you run. All five options deliver the same hardened Langflow image; they differ only in compute capacity. The t3.medium and t3.large are burstable general-purpose sizes for lighter workloads. The m6i.large, m6i.xlarge, and m6i.2xlarge scale up CPU and memory as you move up. Pick the size that matches your workload; the software charge is added on top of standard AWS infrastructure costs. There is no upfront commitment, so you pay only for the hours you run.
Top-of-mind questions for buyers
Each instance ships as a hardened Ubuntu 24.04 image with CIS Level 1 benchmarks applied, CVE scanning, a software bill of materials, and a conformance report bundled inside. Unique credentials generate at first boot. You pay for this pre-configured, security-hardened image plus the running compute hours.
The hourly software charge meters running time only, so a fully stopped instance does not accrue software fees. Stopped instances may still incur standard AWS storage costs for attached volumes. You pay only for the hours the instance actually runs.
The t3.medium and t3.large are burstable general-purpose sizes that accumulate credits during low activity and use them for short bursts. The m6i.large, m6i.xlarge, and m6i.2xlarge deliver steady CPU and memory without a credit system. Both bill per instance-hour at the size you launch.

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
Langflow 1.11.3

- Fixes AWS fallbacks in the Write File component, retries flow updates on SQLite locks, and closes protocol gaps in markdown rendering
- Certbot pre-installed - enable a trusted HTTPS certificate with one command: sudo certbot --nginx -d yourdomain.com
- Rebuilt on the latest CIS Level 1 hardened Ubuntu 24.04 LTS base
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.
