| Pricing | freemium · LangChain and LangGraph are free open-source frameworks. LangSmith pricing starts with a Developer plan at $0/seat/month, then usage-based billing after included trace limits. Plus costs $39/seat/month and adds team features, deployment access, Sandboxes, Engine, email support, and higher included trace volume. Enterprise is custom and adds custom seats, trace volume, SSO/RBAC, SLA, annual contracts, and cloud/hybrid/self-hosted options. | freemium · Langflow does not currently expose a standalone public pricing page in the official Langflow site or documentation crawl. Official sources show a free entry point through Langflow OSS, Langflow Desktop, Docker, and the Python package. The IBM Langflow page lists IBM Langflow Cloud as Private Preview, describes IBM Elite Support for Langflow as a subscription for enterprises that need direct access to Langflow expertise, and describes an integration path with IBM watsonx Orchestrate. None of those pages publish Langflow- specific seat, usage, credit, or support prices. Self-hosted production cost therefore comes from infrastructure, LLM APIs, vector databases, storage, monitoring, security, and team operations rather than a Langflow license fee. |
