Langflow is a powerful open-source, low-code visual platform that lets developers and non-developers build complex AI applications, multi-agent systems, RAG pipelines, chatbots, and LLM-powered workflows using an intuitive drag-and-drop interface. Built on top of LangChain, it provides pre-built components (LLM calls, vector stores, tools, memory, agents, prompts, retrievers, etc.) that connect like building blocks, allowing rapid prototyping, testing, and deployment of production-ready AI solutions without writing extensive code.
Is Langflow Free or Paid?
Lang flow is completely free and open-source at its core (Apache 2.0 license), with the self-hosted/community version available at no cost forever. There is also a managed cloud platform (Langflow Cloud) that follows a paid subscription model for hosted instances, team collaboration, higher usage limits, enterprise-grade security, and managed scaling.
Langflow Pricing Details
The open-source Langflow can be self-hosted at zero cost. Paid options exist only for the official Langflow Cloud (managed SaaS version).
| Plan Name | Price (Monthly / Yearly) | Main Features | Best For |
|---|---|---|---|
| Community (Self-Hosted) | $0 | Unlimited local use, full source code access, all components & integrations, no usage limits (hardware-dependent), custom deployment | Developers, hobbyists, teams wanting full control & zero recurring cost |
| Starter (Cloud) | ~$20–$50 / month (or equivalent) | Hosted instance, basic collaboration, limited concurrent flows, standard support | Small teams or individuals wanting quick setup without DevOps overhead |
| Pro / Team | ~$100–$300 / month (annual discounts) | Team workspaces, version control, higher concurrency, priority support, custom domains | Growing teams, startups, agencies building & sharing multiple AI apps |
| Enterprise | Custom (contact sales) | Dedicated instances, SSO/SAML, SOC 2 compliance, SLAs, advanced monitoring, private networking | Large organizations, regulated industries, production-grade multi-user deployments |

Best Alternatives to Langflow
Several visual/low-code AI workflow builders and agent frameworks offer similar drag-and-drop or component-based development experiences with different strengths.
| Alternative Tool Name | Free or Paid | Key Feature | How it compares to Langflow |
|---|---|---|---|
| FlowiseAI | Free (open-source) + Paid cloud | Drag-and-drop LLM app builder, very similar node-based UI | Extremely close in philosophy & ease; slightly simpler but fewer advanced agent/memory components than Langflow |
| n8n (with AI nodes) | Free (self-hosted) + Paid cloud | General automation + growing AI/LLM nodes | Broader automation scope (not just LLM); less specialized in complex agent/RAG flows vs Langflow |
| Dify | Free (open-source) + Paid cloud | Full LLM app platform with RAG, agents, datasets, prompt playground | Very strong RAG & knowledge base tools; more opinionated UI vs Langflow’s flexible LangChain foundation |
| Haystack (with UI) | Free (open-source) + Paid hosting | Deep RAG & search pipelines | Excellent for retrieval-heavy apps; more code-first originally, UI less mature than Langflow |
| LlamaIndex Workflows | Free (open-source) + Paid cloud | Event-driven workflow engine for agents | Powerful programmatic control; less visual drag-and-drop compared to Langflow |
| CrewAI + UI wrappers | Free (open-source) | Multi-agent orchestration framework | Great for role-based agent teams; requires more code unless using third-party visual layers |
Pros and Cons of Langflow
Pros:
- Truly open-source and self-hostable with zero vendor lock-in or recurring fees for core usage
- Extremely visual and intuitive drag-and-drop interface speeds up prototyping dramatically
- Deep integration with LangChain ecosystem gives access to hundreds of components, tools, and LLMs
- Excellent for building complex multi-agent systems, RAG pipelines, chatbots, and custom AI workflows
- Active community and frequent updates keep the tool cutting-edge
- Supports export to Python code or API endpoints for easy production deployment
Cons:
- Self-hosting requires technical setup (Docker, Python environment, GPU if needed for local models)
- Cloud version starts at a paid tier with usage limits; no generous free hosted plan
- Large/complex flows can become visually overwhelming without good organization habits
- Performance depends on your hardware (self-hosted) or plan tier (cloud)
- Some advanced LangChain features may lag slightly behind the core library
- Steeper learning curve for very complex agent orchestration compared to simpler no-code tools
