Our earlier comparison put Glassly next to Lovable and Bolt, which make websites. This one is for the search you run after that: a Rork alternative, a FlutterFlow alternative, or just which of the tools that really do make mobile apps you should pick. All six below produce native iOS and Android apps. The differences are who they are for, and how much of the last mile is left to you. Facts were checked against each tool’s own pages and documentation in September 2026; tell us if something has moved and we will fix it.
The one question that sorts them
Can you, or will you, run a developer workflow? Three of these tools are built around Expo, the React Native toolchain: you preview through the Expo Go app, build through Expo’s cloud service, and manage certificates and store accounts yourself. That is a good workflow for developers and a wall for everyone else. The other question is the backend: does sign-in and data work the moment the app exists, or is that your homework?
Rork
Prompt to React Native app, previewed through Expo Go on your phone or in the browser, and published through Expo’s build service. It is priced per message to the AI, so the cost of a change depends on how many tries it takes. Rork has pushed hardest on native iOS performance, including 3D games. Best for a builder who is comfortable with an Expo workflow and wants to ship to the stores from one tool.
a0.dev
Also prompt to React Native, with built-in payments and analytics, a choice of backend services to wire in, and one-click submission to both stores under your own developer accounts. There is a free tier for trying it. Best for an indie builder who wants store submission handled and does not mind that the backend is something to choose and connect.
Vibecode
The one you use from your phone: Vibecode is itself an iOS and Android app that builds apps, describing what you want and previewing on the device in your hand. It bills AI usage at cost, through prepaid credits. Best for people who want to build from the sofa and are happy to take the app the rest of the way to the stores themselves.
FlutterFlow
A visual, drag-and-drop builder that produces Flutter code, with AI assistance on top rather than as the way in. Paid tiers add one-click store deployment and code download. It is a serious developer tool with a real learning curve, and the right choice if you want to own and extend the code, or already work in Flutter.
Replit
A coding environment with an agent that, since early 2026, scaffolds mobile apps with Expo. You preview through Expo Go, and iOS publishing is guided through TestFlight with your own Apple developer account. Replit’s own docs say Google Play publishing is not yet a guided experience and is done manually. Best for someone who wants an agent inside a real development environment and is comfortable finishing the Android side by hand.
Glassly
Built for the person who will never open Expo Go. You pick a free template, which is a whole finished app, or describe one in plain English. Glassly plans the screens, writes the code, switches on a managed backend with accounts, a database and file storage, and compiles and signs the iOS and Android builds on its own machines. Android installs from a link and a QR code with no account at all. iPhone installs through your own Apple developer account, which is Apple’s rule for every tool on this page. Changes are asked for in the app’s chat and cost a few credits.
Where Glassly is the wrong choice
If you want to live in the code, use FlutterFlow or Replit. If the app has to pass a regulator’s audit or talk to hardware, hire people. Glassly is for people who do not code and want a finished app on a phone, with the backend included and changes asked for in plain English.
On money
We only state our own prices, with what they buy: every template is free and is a whole finished app; a simple app from your own description is about fifteen credits; a change is a few credits; new accounts start with five free credits; Basic is $5 a month with 50 credits, Pro is $19 a month with 250 credits, Business is $49 a month with 1000 credits. For the other five, read their pricing pages, note whether the price is per message, per seat or per credit, and add Apple’s $99 developer account to any route that ends on an iPhone.
One more thing on words. Vibe coding for mobile apps is what the internet now calls describing an app and letting AI write it. Every tool here does that. The difference is what happens after the code exists, and that is the part to choose on.
Three of these are developer tools with AI in them. Glassly is a builder that ends at the phone. Pick by which sentence describes you.
