Capacity

What is Capacity?

Capacity is a no-code app builder where you describe what you want in everyday words and it produces a working app with a frontend, a backend and its own database. Each project is full-stack by default, so features like user registration create the interface, the API endpoint and the database table together. You can build inside the Capacity editor with its built-in agent, or connect Capacity to Claude or ChatGPT and let your own AI subscription write the code while Capacity handles hosting, versions and domains. Publishing puts the app on a capacity.studio address, and you can connect your own domain. Small business owners and non-technical founders use it for booking sites, shops, scheduling tools and dashboards. Paid plans start at $25 per month with 100 credits for the built-in agent, and building from Claude or ChatGPT does not use those credits.

Use cases

• Build a booking site
• Launch an online shop
• Create a scheduling or invoicing app
• Publish an app on your own domain
• Build apps from a Claude or ChatGPT chat
• Make an internal tool with a database

Who it's for

• Small business owners
• Non-technical founders
• Freelancers
• Creators

Why use Capacity

• You never have to write or read code, since the app is produced from your description.
• Building from Claude or ChatGPT uses your existing AI plan, not Capacity credits.
• Hosting, database, SSL and versions are included, so there is nothing to set up separately.
• Your data and code stay yours, and you can export them if you leave.

How to get started with Capacity

1. Describe the app you want in plain words, in the Capacity editor or from a connected Claude or ChatGPT chat.
2. Capacity builds the pages, data and logins and shows a live preview.
3. Ask for changes in the chat and check each one in the preview, rolling back any version you do not like.
4. Click Publish to go live on a capacity.studio address, and connect your own domain if you want one.

Capacity limitations

• Credits only cover the built-in Capacity agent
• The free Starter server has 256 MB of memory and stops when idle
• Larger servers use credits daily, and running out drops you to the free server
• ChatGPT setup needs developer mode until the connector is in the app directory
