Free Community · paid hosting/features
Connect apps and automate repeated tasks.
Self-hosted Community runs indefinitely without a paid license key. Registered Community also remains free. Business/Enterprise features and n8n Cloud are paid; your server, third-party services and model APIs can add costs. Its source-available license is not a general permission to sell a competing service.

Free self-hosted option · paid managed service
Build and run AI agents that handle recurring work for you.
Self-hosting has no license fee; you pay for infrastructure and model providers. The hosted Platform is paid with usage-based runs. Platform code uses Polyform Shield for personal/internal business use; classic components are MIT, so the whole platform should not be described as MIT open source.

Free self-hosted builder
Prototype AI workflows visually and connect components into runnable applications.
The published Langflow builder has a free self-hosted option. Your server, database, external model APIs and integrations may cost money. Any managed cloud allowance is a separate provider plan, not unlimited free model usage.

Free serving software · compute costs
Serve language models through an inference engine designed for throughput and efficient resource use.
The Apache-2.0 serving software is free. Models, GPU hardware, electricity, storage and cloud compute have separate terms and costs. Installing the runtime does not include a hosted inference allowance.
