How much does Langflow cost in 2026?

Langflow Pricing (as of March 2026)

Open-Source (Free)

The Langflow open-source project is available on GitHub and can be installed via pip (pip install langflow) or Docker. The self-hosted version includes the full visual builder, all pipeline components, and no restrictions on usage. The only costs are infrastructure (a VPS with 4 GB RAM runs Langflow comfortably at $10-20/month) and LLM API fees for the models used in pipelines.

Cloud Free Tier

The DataStax-hosted cloud version includes a free tier with limited monthly executions (the exact limit varies and is updated periodically). The free tier provides access to the visual builder, standard components, and Astra DB integration. It is designed for prototyping and evaluation rather than production workloads. Single-user access only — team collaboration requires a paid plan.

Cloud Paid Plans

Paid cloud plans start at approximately $25 per month and provide higher execution limits, team collaboration features, persistent flow storage, and priority support. The integration with DataStax Astra DB is included, with Astra DB usage billed separately based on storage and read/write operations. Pricing scales with the number of executions per month and team size.

Total Cost Estimation (Self-Hosted)

Self-hosted Langflow is cost-effective for teams that already have infrastructure and LLM API access. The primary variable cost is LLM usage, which depends on the complexity and volume of pipeline executions.

Editor's Note: We ran a self-hosted Langflow instance for 2 months during a RAG prototype project. Infrastructure: $15/mo (Hetzner VPS). LLM costs: $65/mo average (OpenAI embeddings + GPT-4 retrieval). Total: $80/mo for unlimited experimentation. The cloud free tier was sufficient for initial prototyping (5-10 test runs per day) but would have required the paid plan for our production evaluation phase (50+ daily executions).
