Langflow
A visual builder for AI workflows and agents: drag components onto a canvas, connect them, and expose the result as an API.
Install & harden · $249 one-time | Hosted & monitored · $99/mo
What it does
Assembles flows from prompts, models, memory, tools and logic blocks, without framework boilerplate.
Tests every flow in a built-in playground before anything goes live.
Publishes flows as API endpoints your applications and other agents can call.
How it fits your stack
Flows become HTTP endpoints that n8n, Activepieces or your own backend call as steps.
We wire authentication and TLS so exposed flows are never an open door to your models.
Every install ships with
Hardened Docker deploy. Isolated containers behind a TLS reverse proxy, firewall rules applied.
Least-privilege keys. Model and exchange keys scoped to the minimum, stored server-side.
Access control. Authentication in front of every interface. Nothing listens naked on the internet.
Documented handover. Credentials, architecture notes and a rollback path, in writing.
Pricing
Fixed prices, billed in USD through Stripe. The one-time install is yours forever; the hosted plan renews monthly.
One-time. Hardened deploy on our host or yours, scoped keys, documented handover.
Monthly. Single-tenant hosting, 24/7 monitoring, updates and backups handled for you.
Questions
Is Langflow only for LangChain users?
No. It is a standalone visual platform: you build flows in the browser and call them over HTTP. No LangChain knowledge is required to use what we deliver.
Who can access my flows once hosted?
Only your team. The instance is single-tenant, behind TLS and authentication, and the API endpoints require keys we generate for you.
What do I need to bring?
Your model API keys (or a local model), and the use case. We handle the server, the hardening and the first flow with you.
Ready when you are.
Buy the install and we schedule it within days, or talk to an engineer first. Either way, you end up with a hardened instance and the keys in your hands.
