What is Capacity?
Capacity is a no-code platform for building real web apps from a plain-language description. You explain your idea like you would to a friend, Capacity asks a few clarifying questions about purpose, users and feel, then builds the app and publishes it with hosting, a database, logins and an optional custom domain.
You can build either inside Capacity with its built-in agent, which uses credits, or from Claude or ChatGPT by connecting Capacity to your existing subscription. In the second case the chat writes the code and Capacity runs it, handling hosting, database, domain and version history. Each change is previewed immediately, and the same app can later be opened in Capacity.
