Gemmein vs Lovable
Lovable is one of the best ways to conjure a new app from a prompt — and its Cloud and Payments keep that app running inside Lovable's world, on its credits. Gemmein doesn't build apps at all. It's the layer a finished app stands on: sign-in, customer data with enforced rules, payments through your own Stripe, and the console you run it all from. Different moments, honestly different tools.
Lovable is a place your app is born. Gemmein is what it stands on when it grows up — wherever it was born.
Paste it to the AI you already build with — Claude Code, Codex, Cursor, Bolt — it reads the guide and answers for your app.
Side by side
| Lovable | Gemmein | |
|---|---|---|
| What it is | An AI app builder with its own cloud and payments | The go-live layer under an app built anywhere |
| Who writes the app | Lovable's AI, in Lovable's editor | Any AI you already use — or yourself |
| Where the app lives | Lovable Cloud, on plan + usage credits | Anywhere; Gemmein never hosts your app |
| Sign-in | Cloud-provided auth | Passwordless email codes — no passwords anywhere in the system |
| Customer data | Cloud database, usage-billed | Seven plain-English safety rules, server-enforced, nothing to configure |
| Payments | Lovable Payments on their rails | Your own Stripe — Gemmein never holds, moves, or processes money |
| Who owns the customer | Accounts live in their cloud | You — in your Stripe, your records, your console |
| Cost shape | Plan ($25–50/mo) plus credits and usage that scale with the app | Free while you build; live is one banded plan, $50–$150/mo by real monthly people — no metering |

When Lovable is the better choice
- You're starting from a blank page and want the fastest possible idea-to-running-app loop, in one place, without leaving the browser.
- You want the builder and the runtime to be the same product, and you're comfortable with usage-based cloud costs as the app grows.
- Your app is an experiment you may throw away — the speed matters more than owning the foundations.
When Gemmein is
- The app is past the experiment stage and you want the parts that touch real people — accounts, money, private data — owned by you, not metered by a builder.
- You build with your own AI tools and your own repo, and you want to keep doing that.
- You want a bill that doesn't move with usage: free to build, one banded price live, capacity that follows your real people.
- You want a back office made for operating — customers, refunds, audit — not a developer dashboard.
Questions
If you can export the frontend code and host it yourself, yes — the app talks to Gemmein through a small SDK, and your AI does the wiring. Ask it: paste docs.gemmein.com/llms.txt and request a fit verdict on your app first — it will name anything that doesn't map before you commit to anything.
No — and that's the point. Your app's code and hosting stay wherever you like (Vercel, Cloudflare, any static host). Gemmein is the layer underneath: sign-in, customer records with server-enforced safety rules, Stripe-run subscriptions and purchases, and the operator console you run the business from.

You do — deliberately. With Gemmein, every payment lands in your Stripe account and the customer is legally your customer. Merchant-of-Record platforms (Paddle, Lemon Squeezy) flip that trade: they become the seller of record, their name is on the card statement, and your customer is contractually theirs — in exchange they carry the tax filing. Both are legitimate. Selling digital products to EU consumers can create VAT duties from the first sale, and at heavy international volume a Merchant of Record genuinely earns its cut. For most independent founders under the UK's £90,000 VAT threshold, with Stripe Tax able to calculate what's owed, you're deciding whether to hand over the customer relationship to avoid paperwork you may not have yet. Gemmein never holds, moves, or processes money either way — that's Stripe's job, in your account.
Web apps only — no native mobile SDKs today. No team or workspace visibility scopes, no per-user record permissions, no carts or physical goods, no multi-seller payouts, no hosted functions or cron (your server-side code runs on your own host with a secret key). If something isn't in the builder guide, it isn't built — the guide says so out loud rather than letting an AI invent a workaround.
