Use an AI assistant to write and edit code.
OpenCode software is MIT-licensed and free. A local model uses your own hardware; paid provider APIs or subscriptions bill separately. Optional OpenCode Go is USD 10/month and Go Plus USD 40/month, with model-specific usage limits.

Add a database, user accounts, and file storage to your app.
The hosted Free plan has limited database, bandwidth and storage allowances. Pro starts at USD 25/month; extra projects, compute, storage and add-ons can add charges. Self-hosting uses your own infrastructure rather than including managed cloud resources.

Create structured databases and internal applications through a visual, no-code interface.
A USD 0 plan is available with edition-specific limits. Premium is USD 12/user/month billed monthly or USD 10/user/month on annual billing; Advanced is USD 22 monthly or USD 18 on annual billing. Self-hosted paid features and your own infrastructure have separate costs.

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.

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.

The Free API-testing plan costs USD 0. Business is USD 6/user/month and Enterprise USD 11/user/month, both billed annually on the observed cloud plan. Self-hosting and selected features have separate edition terms.
