The main alternatives for building a native mobile app without code fall into three camps: AI builders you prompt in plain English, visual builders that can hand you the source code, and platforms built for businesses or large companies. Choose the camp first, then check whether you can take the code with you and on which plan.
You've got an app idea, or an app that already works, and you want it on people's phones without hiring a development team. That's the job Adalo was built for, and it's the job every tool below is trying to do as well, each in its own way.
People move for different reasons. Some want an AI that builds screens from a description. Some want to see the code underneath. Some run a business that needs branded apps, or a company that needs one platform for dozens of internal apps. The seven options here are in no particular order and grouped by that reason, because it decides which one will feel like home.
Prompt, drag or govern: three kinds of mobile app builder
AI and prompt-led builders. These start from a conversation. You describe the app, the tool writes screens, and you keep chatting until it looks right. Rork is the clearest example: it builds for iOS, Android and the web and publishes to both app stores. The React Native builder in this list works in a similar way, turning plain-English requests into real screens.
Visual builders with code you can see. These give you a canvas and, depending on the tool and plan, a route to the code it produces. One is built on Flutter. Another generates the backend as well as the app. Backendless sits close to this group but isn't a pure mobile builder: it's a low-code platform that bundles the screens, the logic, the database and messaging, so you're choosing a whole stack rather than an app builder alone.
Business and enterprise platforms. BuildFire is aimed at businesses and agencies, not hobbyists, with white-label apps you can publish under a client's brand. Mendix is the one big brand on this list, an enterprise low-code platform from Siemens built for companies running many apps across departments. If you're a solo founder with one idea, it's more platform than you need.
The seven builders in one table
| Tool | Kind of builder | Good for |
|---|---|---|
| AppMaster | No-code builder that generates source code | Backend, web and native apps from one project |
| Backendless | Low-code UI plus backend platform | Designing web and mobile screens together over one database |
| BuildFire | Business and white-label app platform | Businesses and agencies publishing branded apps |
| FlutterFlow | Visual builder with Flutter code export | Visual building with the option to write Dart |
| Mendix | Enterprise low-code platform | Large companies running apps across departments |
| RapidNative | Prompt-to-React-Native app builder | Plain-English prompts that become React Native screens |
| Rork | Chat-driven AI mobile app builder | Chatting your way to an iOS, Android and web app |
Who each builder suits
Alphabetical, in no particular order.
AppMaster
Best for: Builders who want production apps with the backend included, a low-code and no-code backend-plus-app platform more than a pure mobile builder, with generated source code.
Backendless
Best for: Teams that want the screens, codeless logic, a real-time database and messaging in one place, designing web and mobile at the same time, with a choice of hosting.
BuildFire
Best for: Businesses and agencies, not hobbyists, that want custom iOS and Android apps designed, built and published, with white-label apps and a store publishing service (vendor claims).
FlutterFlow
Best for: Founders who want to describe an app, refine it visually, drop in custom Dart where needed and send it to the App Store and Google Play (vendor wording).
Mendix
Best for: Larger organisations that want one enterprise low-code platform for the workflows, agents and applications the company runs on; it's the big brand here, part of Siemens.
RapidNative
Best for: Founders who'd rather type what they want in plain English and get real React Native screens, with a store-submission service on offer (vendor claim).
Rork
Best for: People who want to build by chatting, with separate native Swift, Kotlin and web products and an AI reviewer the vendor says catches App Store rejections early.
Owning the code versus owning a store listing
Here's the trap. Getting your app into the App Store feels like ownership, but it isn't the same thing. If the only copy of your app lives inside a builder's editor, you're renting it. The day you want a developer to take over, or the builder changes direction, you start again.
So before you leave, and before you pick a replacement, ask three things: can I download the source code, in what language, and on which plan. The answers differ more than the marketing suggests. FlutterFlow says you can export clean Flutter whenever you want. AppMaster advertises one-click export of the full source code as a repo-ready package. RapidNative's own FAQ says code download comes with its plans you pay for, not the starting tier. The builder you're leaving may make export promises too, so check what it hands over before you switch.
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
The language matters as much as the export. Flutter code needs a Flutter developer. React Native code needs someone comfortable with JavaScript and React. A generated backend needs someone who can run a server. Where the code lands decides who you can hire to look after it next, so think about that person now, not after launch.
My advice for founders leaving their app builder
Start with the smallest version of your app that people would use, and build that one screen flow in two tools before you commit. If you're a non-technical founder who wants speed, try the AI builders first. If you already know you'll hire a developer within a year, lean towards the visual builders that export code, and make sure the export is on the plan you'll be on. If you're building for clients or for a large company, the business platforms are designed for that work and the others will feel thin.
And be honest about whether you need a native app at all. My piece on whether your business needs a mobile app is worth five minutes before you start. If AI building is what draws you, my wider list of AI app builders covers web apps as well as mobile.
Five questions for the first demo
Put these to every vendor before you move a single screen:
- Can I export the source code, in which language, and on which plan?
- Who submits the app to the App Store and Google Play, and who holds the developer accounts?
- Where does my data sit, and can I export it in a format another tool can read?
- What happens to my live app if I stop using your platform?
- Can I add custom code when the visual tools run out?
Write the answers down. If a vendor can't give a straight reply to the first or fourth question, that tells you a lot about how hard leaving will be later.

Frequently asked questions
Can I build a native iOS and Android app without code?
Yes. Several builders publish to both app stores from one project. Check who holds the store developer accounts and whether the app keeps working if you leave the builder.
What's the difference between a no-code and a low-code app builder?
A no-code builder lets you make an app without writing code at all. A low-code platform also uses visual tools but expects that a developer will add code for the harder parts.
Can I move my app from one no-code builder to another?
Rarely as a straight import. Your data and images usually move, but screens and logic tend to be rebuilt. That's why source code export matters before you commit.
Is Flutter or React Native better for a no-code app?
Neither wins outright. Both build apps for iPhone and Android. Pick the one a developer you might hire later already knows, because they'll be the one maintaining the code.
Are AI app builders good enough for a real product?
They're fast for a first version and for testing an idea. For a product people rely on, check you can see and export the code, and plan for a developer to review it.
Do I need a web app as well as a mobile app?
Not always. Some builders publish to iOS, Android and the web from one project, which helps if your customers use a laptop as often as a phone.
