A Mac app that turns plain English into real apps — built and stored on your machine, not someone else's servers. Your code, your GitHub, your own AI at cost. No marked-up credits, no lock-in. Free, no sign-up. macOS (Apple Silicon), Windows on the roadmap.
Hey Product Hunt 👋
We're Baptiste & Samuel — two product people who spent the last year obsessing over one question: why does "AI builds your app" have to mean "your app lives in someone else's browser tab"?
We love what Lovable and Bolt made possible. We just wanted the magic without the rent: no marked-up AI credits, no code held hostage in a cloud workspace, no export button as an afterthought.
So we built Capacity — a free Mac app that turns plain English into real web, mobile, desktop and game apps, built and stored on your machine.
• 🎨 Start from 80+ hand-picked design templates — or import a repo you already have
• 🧠 Bring your own AI: Claude, GPT, Gemini, Grok, Kimi, DeepSeek… your key, billed at cost, with a built-in spend dashboard
• ⏪ Every change becomes a restorable version — if the AI takes a wrong turn, roll back in one click, and nothing is ever lost
• 🚀 Publish tab: connect GitHub + Vercel, preflight your env vars, deploy in one click and watch it go live
• 🛠️ Zero terminal: Capacity detects the dev tools each project needs (Git, Node…) and installs them for you
• 📁 Your project is a normal folder and git repo — open it in any editor, hand it to any developer, walk away anytime
There are just two of us, and we've sweated the details most builders skip — the restore timeline, the empty states, the way a deploy feels. We wanted a Mac app that feels like a Mac app.
The honest bits:
• macOS (Apple Silicon) only for now. Windows and Linux are on the roadmap — tell us in the comments which one you need.
• You bring your own AI key. That's the philosophy: we sell a tool, we don't resell tokens.
• Free while in beta. When we charge later, the plan is a one-time license — never a subscription, never credit markups.
⬇️ Try it now: capacity.so/desktop — free, no sign-up, building in under a minute.
We're both here all day. Tell us what breaks, what's missing, and what you'd build first 🙏
