What Is langflow?
Langflow is an open-source, MIT-licensed visual builder for LLM application workflows, free to self-host with no license fees or usage restrictions on the software itself. A significant hosting change occurred in 2026: DataStax's managed cloud hosting for Langflow was deprecated March 9, 2026 and fully shut down April 9, 2026 — but the open-source project itself continues actively, with DataStax (now being acquired by IBM) committing to keep Langflow "forever open, free, and agnostic."
Since the managed hosting option is gone, deploying Langflow in production as of 2026 means exporting a flow as JSON and running it via Docker or Kubernetes, then exposing it as a REST endpoint — while the core software remains free, real costs shift to infrastructure hosting ($5-500+/month depending on scale), LLM API usage ($10-1,000+/month), and optionally vector databases and monitoring tools, with self-hosting for hobby use running roughly $30/month versus $150-2,000+/month for team or enterprise deployments.
It's aimed at developers building visual LLM workflows who are comfortable self-hosting via Docker or Kubernetes now that the managed cloud option has shut down, with the software itself remaining completely free while real total cost depends entirely on chosen infrastructure and LLM API usage.

langflow Pros & Limitations
What We Like
- Genuinely free, MIT-licensed open-source software with no usage restrictions
- DataStax/IBM has committed to keeping Langflow "forever open, free, and agnostic"
- Visual workflow builder makes LLM application design accessible without extensive coding
Limitations
- DataStax’s managed cloud hosting was fully shut down April 9, 2026 — self-hosting is now required
- Real total cost shifts to infrastructure hosting and LLM API usage, ranging widely ($30-2,000+/month)
- Production deployment now requires comfort with Docker or Kubernetes rather than a managed option

Frequently Asked Questions
Is Langflow still free?
Yes, the open-source, MIT-licensed software remains completely free to self-host.
What happened to DataStax’s hosted Langflow?
It was deprecated March 9, 2026 and fully shut down April 9, 2026; the open-source project itself continues.
How do I deploy Langflow now?
By exporting a flow as JSON and running it via Docker or Kubernetes, exposed as a REST endpoint.
What does self-hosting actually cost?
Roughly $30/month for hobby use up to $150-2,000+/month for team or enterprise deployments, covering infrastructure and LLM API usage.
Our Take
Langflow's open-source core remains genuinely free and actively committed to staying that way under DataStax/IBM, even after the managed cloud hosting shut down in April 2026.
Budget for self-hosting infrastructure and LLM API costs separately, since the "free" software itself is only part of the real total cost of running it in production.
