Capacity is for people with an app or website idea who want to build it without writing code, including small businesses creating tools for their customers. Describe what you need in plain English, then refine the result by chatting with the AI and reviewing a live preview. Use Capacity to make landing pages, websites, online stores, booking and ordering tools, or fuller web apps with data and user logins. Publish a working version online and connect a custom domain. Developers can also take the generated code with them, while people who prefer to build from an AI chat can connect Capacity to Claude or ChatGPT.
