Capacity

Build and publish web apps through conversational instructions

Meet Capacity

Capacity is an app builder for people who want to turn an idea into a working web application through conversation. Describe a booking service, storefront, client gallery, or another workflow, then review the generated pages and request changes in chat. The platform handles supporting pieces such as data storage, user accounts, hosting, and version history.

Users can start inside Capacity or connect it to supported AI assistants, with the latter using the assistant subscription for generation. A preview helps refine the app before publishing it to a shareable address or connecting a custom domain. It is suited to testing business ideas and building practical small applications, with the resulting behavior still needing review before launch.
