What is Capacity?
Capacity is a no-code app builder for founders and others who want to turn an idea into a working website or application without writing code. Describe the product in everyday language, answer follow-up questions, and Capacity builds pages and data that you can preview and revise through chat. It can publish the result with hosting and a shareable link, and also supports building through Claude or ChatGPT using your own AI subscription.
Capacity Features:
Natural Language Building: Describe an app in plain words, and Capacity asks questions to clarify the idea before building it.
Live Preview: See the app as it is built, then request changes in chat and review them in the preview.
App Essentials: Create apps with member accounts, logins, saved information, and payment capabilities.
Publishing and Domains: Publish an app online with a shareable link and connect a custom domain.
Claude and ChatGPT: Build from Claude or ChatGPT, with those services writing the code while Capacity provides hosting, a database, domains, and versions.
Version History: Keep version history when switching between building in Capacity and working through Claude or ChatGPT.
Responsive Design: Create designs intended to work on phones, tablets, and computers, and describe the style you want in chat.
Capacity Benefits:
Lower Barriers: People without coding or design experience can move from an idea to a working app by describing what they want.
Faster Validation: A previewable app gives founders a way to try an idea and share it before committing to a longer development process.
Fewer Handoffs: Keeping requests, previews, and revisions in a conversation helps nontechnical builders make changes without translating them into code.
Clearer Ownership: Keeping the app, data, and members under your ownership makes it easier to retain control of the product you build.
Flexible Building: Using an existing Claude or ChatGPT subscription for building can help avoid relying solely on Capacity agent credits.
Use Cases:
MVP Prototyping: Turn an early product concept into a working MVP that can be previewed and shared with potential users.
Online Stores: Create an e-commerce site for presenting products and building a custom shopping experience.
Appointment Booking: Build a reservation or scheduling site for appointments, events, or other bookable services.
Internal Operations: Make an internal business tool such as an admin panel, dashboard, or workflow management app.
SaaS Launch Pages: Put together a B2B SaaS site with product information, pricing tiers, demos, or a customer portal.
