Turn a plain-language idea into a real, live web app — no code required
Type a short description of your idea and Capacity asks a few questions, then builds the pages, data and logins in minutes with a live preview.
Generated apps can include member accounts, logins, saved data and payments, not just static mockups.
Connect Capacity to Claude or ChatGPT and build from the chat; each message runs on your AI plan rather than Capacity credits.
One click publishes the app to the internet, and you can attach a custom domain name in minutes.

Describe the app you want in ordinary language and Sparkable scaffolds a working React project in seconds.
Your app runs inside the browser immediately, so you can click through real behaviour instead of inspecting static mockups.
Open the generated source, tweak components, add logic and pull in any package from the npm ecosystem.
Generated apps can call real external APIs, making it possible to build projects that use live data rather than placeholders.
