Building apps,
on your own terms.
As with Lovable, you describe an app and the AI builds it. Unlike Lovable, this app builder runs on your Mac or Windows PC, on the AI plan you already pay for.
Your AI, at true cost
Sign in with Claude and Capacity runs Claude Code on your plan, or use ChatGPT or an API key. No marked-up credits: you pay your provider, and a dashboard shows what you spend.
Build anything
One app builder for websites, web apps and desktop apps, with live preview built in and the right AI model for every job.
Your code, never hostage
Your app lives on your computer and pushes automatically to your own GitHub and Vercel. Open it in any editor, hand it to any developer, walk away anytime.
Undo anything
Every change is saved as a version while you build. If the AI takes a wrong turn, restore any earlier version in one click — nothing is ever lost.
From idea to
live on the web.

01
Start from a real design
Choose one of 80+ designer templates — or a blank canvas. A guided setup names your project and connects GitHub and Vercel for you.
02
Describe. Watch it build.
Say what you want in plain English. Capacity plans first, then Claude Code or the model you pick builds it on your computer while the live preview updates in front of you.
03
Publish in one click
Capacity checks your production settings, pushes your code, and follows the deploy until your app is live at its own URL.
04
Change it without fear
Every step is saved to your project history. If anything goes wrong, restore an earlier version in one click.
Start from a designer template
80+ hand-picked designs ship inside the app — portfolios, landing pages, storefronts. Pick one and the AI rebuilds it around your idea, so your first version already looks professional.

A plan you can read, before any code
Vibe coding works better with a plan. For every feature, Capacity writes a plain-English spec first: review it, correct it, then let it build. Fewer surprises, less wasted AI spend.
Built-in live preview
Your app runs right inside Capacity while the AI works on it. Watch every change land in real time — no tabs, no setup.
Publish to the web in one click
The Publish tab lines up your GitHub repository, your Vercel project, and your production settings — and checks them before anything ships. Press the button and watch your app go live at its own URL.
Every version saved. Undo anything.
Capacity saves a snapshot after every AI step. If a change breaks something — or you just preferred yesterday's look — restore any version in one click. Restores never delete your newer work.
Claude Code, ChatGPT and more
Use Claude Code with your Claude plan, GPT models with your ChatGPT plan, or an API key for Gemini, Grok, DeepSeek, Kimi and others. Switch models per task and pay your provider directly, at cost.
