Frequently asked questions

Join our Discord.
Is OpenUI free and open source?
Yes. OpenUI is fully open source and works with your own models, infrastructure, components, and design system.
OpenUI Gateway and OpenUI Observability are managed services for teams running Generative UI in production.
Which model handles corrections, and are they billed separately?
Corrections use a dedicated model tuned for low latency, which we continue to improve. All correction calls are included in your plan and are not billed separately.
What does OpenUI Observability cost?
OpenUI Observability is free during early access. Pricing will be published before paid access begins.
Do I need both Gateway and Observability?
No. They work independently.
We recommend using both. Gateway makes generated UI more reliable. Observability shows what users experienced and whether it worked.
