A FlutterFlow alternative — native code, agent-built, free to ship

FlutterFlow's free tier is genuinely useful and honestly bounded, and the boundary is the single most practical fact on this page. Free gives you the visual environment, a thousand-plus templates, two projects, API and data integration, and web publishing. What it does not include: code download, APK builds, and App Store deployment — all of which begin at Basic, $39 a month (monthly billing), alongside unlimited projects and local device testing.

That is a clean freemium design, not a trap — but know what "free" means before you invest a weekend: free to build and try, not free to ship or to leave with your work. The moment your app should reach a phone or your code should reach your own repository, the meter starts at $39.

Modaal draws the line differently on purpose. The free plan is one active project with unlimited prompts, and the code is on your own disk from the first build — there is no export gate because there is nothing to export from. Shipping through TestFlight and the App Store comes with Pro at €9 a month billed annually. So the comparison at the entry point: on one side, $39/month to hold your own code; on the other, code you hold from minute one and €9 when you are ready to distribute.

Both tools hand you real code, which puts them above most of this category. They hand you different code.

FlutterFlow outputs Flutter — Google's framework, "powered by Dart", compiling "to ARM or Intel machine code", building "natively compiled, multi-platform applications from a single codebase." The honest description of the trade: Flutter draws its own interface. That is how one codebase stays pixel-identical on iOS, Android and web — and it is why a Flutter app renders Flutter's widgets rather than the platform's own, with the depth-of-OS-access and feel implications that follow. For many products this never matters; for some it decides everything, and the long version of that argument is at Swift or React Native?.

Modaal outputs the platform's own materials: Swift and SwiftUI on iOS, Kotlin and Jetpack Compose on Android — two native codebases, with Duet keeping their logic provably in step. The cost of that choice is symmetrical and the table below says so: you do not get one project running on the web, and you do not get a single codebase.

One practical note on FlutterFlow's export, quoted from their docs because it surprises people later: with the GitHub integration, "FlutterFlow always pushes changes to a branch named `flutterflow`. Avoid making direct changes to this branch, as your changes will be overwritten by the next push from FlutterFlow." Your custom code lives on a separate branch you merge into. That is a workable model — but it means FlutterFlow remains the source of truth while you use it, which is a different kind of ownership than a project whose only author-of-record is your own repository. Credit where due: it is still far more export than Bubble (none) or Adalo (none we could find documented) offer.

The deepest difference is not in the output but in the hands.

FlutterFlow is visual assembly: you place components, wire actions, bind data — you are the builder, with excellent scaffolding. The skill it rewards is UI thinking, and the thousand templates mean you rarely start from white canvas. If you enjoy that work, FlutterFlow is that work, done well.

Modaal is agent building: you describe the feature, and an AI agent writes the Swift, compiles it through Xcode, reads its own build errors, fixes them, and shows you the result running. You steer in sentences, not drags. The skill it rewards is knowing what you want — and its economics ride on the AI subscription you already have (Claude, ChatGPT and eleven others), with nothing metered on Modaal's side, on any plan.

Which model wins depends honestly on you. Builders who think visually often find describing frustrating; founders who cannot design a screen find assembling slower than saying what they mean. The cheap way to find out is to spend one afternoon on each free tier — that experiment costs nothing on either side and settles more than this page can.
