Gemmein vs Base44
Base44 is an all-in-one AI app builder: you describe the app, its AI builds it, and the app lives — frontend, database, hosting — inside Base44's platform. Gemmein starts from the opposite end: you build wherever and with whichever AI you already use, and Gemmein is what takes the finished app to real customers. These solve different moments, and one of them may honestly be right for you.
Base44 is where an app gets made. Gemmein is what an app you already made stands on when real people show up.
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
| Base44 | Gemmein | |
|---|---|---|
| What it is | An AI app builder — describe it, their AI builds and hosts it | The go-live layer under an app built anywhere — sign-in, customer data, payments, back office |
| Who writes the app | Base44's built-in AI, in their editor | Any AI you already use — Claude Code, Cursor, Codex, Bolt — or your own hands |
| Where the app lives | Inside Base44's platform, on their hosting | Anywhere you like; Gemmein never hosts or touches your code |
| Sign-in | Built-in platform auth | Passwordless email codes — no password database exists to breach |
| Customer data | Platform database | Collections under seven plain-English safety rules, enforced server-side, on by default |
| Payments | Platform integrations | Your own Stripe — Gemmein never holds, moves, or processes money |
| Who owns the customer | Accounts live in the platform | You — their email, their records, their subscription, in your Stripe and your console |
| Running the business | Builder workspace | An operator console: customers, subscriptions, refunds via Stripe, audit record |
| Price shape | Credit-based plans, free to ~$200/mo | Free while you build; live is one banded plan, $50–$150/mo by real monthly people |

When Base44 is the better choice
- You don't have an app, a codebase, or an AI workflow yet, and you want one tool that does all of it — describing an app and getting a hosted result the same afternoon is genuinely what Base44 is for.
- You never want to see code or a terminal, even through an AI assistant.
- You want your builder, database, and hosting to be one bill and one dashboard, and you're comfortable that the app lives inside that platform.
When Gemmein is
- The app already exists — vibe-coded in React, built in Cursor or Claude Code — and what's missing is real accounts, real payments, and somewhere to run the business from.
- You want the code to be yours: in your git, on your hosting, portable on the day you want to leave.
- You want the money in your own Stripe and the customer relationship in your own hands.
- You'd rather have seven safety rules that can't be misconfigured than a platform surface you have to trust blind.
Questions
If it's a web app in JavaScript or TypeScript whose code you can host yourself, yes — Gemmein doesn't care which AI wrote it. Point your AI at docs.gemmein.com/llms.txt and it will map your app against what Gemmein supports and give you a fit verdict before anything installs.
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. Build anywhere. Launch with Gemmein.
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.
