Free self-hosted UI · model costs
Chat with AI models in your own browser-based workspace.
Use the self-hosted UI with its required branding under the current license. There is no included paid-model allowance: cloud APIs, servers and storage can cost extra. Removing branding or qualifying enterprise uses may require a separate license; do not assume the current release is unrestricted BSD.

Free Sandbox · paid cloud plans
Build AI chatbots and automated workflows.
Cloud Sandbox is free with limited credits and storage. The provider lists Professional at USD 590/workspace/year and Team at USD 1,590/workspace/year on annual billing, before applicable taxes. Community self-hosting uses your infrastructure; model API keys and paid features can add costs.

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.
