The four limits that end serious Bubble projects, made specific to this comparison. Each one is sourced.
Zero code ownership — the whole comparison turns on this
No exportBubble has no source-code export. FlutterFlow's headline feature is that it does: you can download the full Dart project and keep developing it in a real IDE. If owning the code is on your list at all, that single difference decides the page. On Bubble, the platform is the product, and leaving means rebuilding.
BlockerSources: [5]Web only — no native mobile output
Web + PWABubble produces responsive web apps and PWAs. To reach the App Store or Play Store you wrap the web app, and Apple rejects thin wrappers. FlutterFlow compiles genuine native iOS and Android from Flutter. If a real native app is the goal, Bubble is the wrong starting point.
MajorSources: [5]Workload-Unit billing scales with activity
$0.30 / 1k WUBubble meters app activity as Workload Units, billed around $0.30 per 1,000 WUs above your allowance, so cost tracks traffic rather than team size or revenue. FlutterFlow bills per editor seat with no usage-metered runtime fee, though you pay Firebase/Supabase and app-store fees separately. Different curves, but Bubble's is the one that surprises people at scale.
MajorSources: [4]300-second server-workflow timeout
300sBubble kills a server workflow at 300 seconds, so long imports, exports, and syncs must be chunked around the limit. FlutterFlow pushes heavy work to Firebase Cloud Functions or Supabase, where you set the constraints. The ceiling here is Bubble's own, and it's a real wall for data-heavy background jobs.

The real, researched limits on FlutterFlow — not generic ones. If a limit matters to your app, it's here.
No built-in database — you assemble the backend
FlutterFlow ships no database of its own. Data lives in Firebase (Firestore) or Supabase, which you set up, secure, and pay for separately. That's more flexible than Bubble's all-in-one model, but it's also more to manage: Firestore enforces roughly one write per second per document and a 1 MB document cap, and read-heavy apps scale in cost. Bubble bundles the database; FlutterFlow makes it your job.
MajorSources: [2]Source-code export is paywalled at the Basic plan
$39/mo gateThe Dart export that makes FlutterFlow compelling is not on the Free plan — it starts at Basic, around $39/mo. Until you pay, you can't download the code, which quietly undercuts the 'you own it' pitch for anyone evaluating on the free tier. It's still real ownership, just gated behind a paid seat.
Exported code carries FlutterFlow scaffolding
The Dart you export is real and yours, but it's generated code with FlutterFlow's own structure and helper layers. Extending it well needs Flutter developers, and once you leave the visual editor you maintain that scaffolding by hand. It's a genuine head start on ownership, not a clean hand-written codebase.

Pricing compared
What each one costs when it stops being a demo.
The sticker price rarely decides it. What matters is the axis your bill grows along once real users arrive.

Bubble
from ~$32/mo- Billing model
- Usage-metered Workload Units on top of a plan tier
- What drives cost up
- Workload Units consumed by app activity
Includes a WU allowance; overage bills around $0.30 per 1,000 WUs. The database and hosting are bundled, but the bill climbs with traffic.
FlutterFlow
$39/mo (Basic; ~$29.25 annual)- Billing model
- Per-seat subscription (no usage-metered runtime)
- What drives cost up
- Editor seats + your Firebase/Supabase bill + app-store fees
Growth ~$80/mo and Business ~$150/mo add seats. The backend is billed separately by Firebase/Supabase, so the true cost is seats plus infrastructure.
What happens at scale
FlutterFlow's cost tracks team size and backend usage, so a high-traffic app can be cheaper than Bubble's WU bill — but you're now paying for and running the backend yourself. Bubble is simpler to reason about while small, and harder to forecast once busy.
Which one should you choose
The honest pick-this-if split.
Pick Bubble if…
- You're building a web app, not a native mobile app.
- You want the database, logic, and UI in one platform with nothing to assemble.
- You don't have Flutter developers and don't plan to hire any.
- You're validating fast and code ownership isn't a near-term concern.
Pick FlutterFlow if…
- You need genuine native iOS and Android apps, not a wrapped web app.
- You want to own and keep developing the exported Dart source.
- You have (or will hire) developers who can extend Flutter code.
- You'd rather choose and control your own backend and hosting.
The named limit
"Exports code" is true — but read the asterisks
FlutterFlow's export is the sharpest advantage over Bubble in this whole hub, and it's real: full Dart, downloadable as a ZIP. The asterisks matter, though. Export is gated at the ~$39/mo Basic plan, so the free tier can't take the code at all. The output carries FlutterFlow's scaffolding, so extending it needs Flutter developers. And there's no built-in database, so the backend (Firebase or Supabase) is a separate system you own and pay for. Net: FlutterFlow gets you to owning code; a rebuild gets you to owning code that was written to be maintained.

When neither is the answer
When the honest answer is code you own.
FlutterFlow already gives you a real exit — the Dart export — which is more than Bubble offers. But an export is a starting point, not a finished codebase: it carries generated scaffolding, and it still leans on a backend you assemble. When the app is past validation, has real users, and needs to be maintainable for years, the honest move is a clean rebuild in code you own — a proper database, an app layer you control, and a codebase written to be extended rather than generated. From Bubble that's the only way to own it at all; from FlutterFlow it's the upgrade from generated to maintainable.
Frequently asked
FlutterFlow vs Bubble — the questions buyers ask.
Straight from the People-Also-Ask box on the live search results. Answers grounded in the sources cited on this page.
- Q01Is FlutterFlow better than Bubble for native mobile apps?
- For genuine native apps, yes. FlutterFlow compiles real iOS and Android from Flutter and publishes to both stores, while Bubble produces responsive web apps that need a wrapper Apple may reject. If your product must feel native and live in the app stores, FlutterFlow is built for it and Bubble is not.
- Q02Can I export code from FlutterFlow but not from Bubble?
- Correct. FlutterFlow lets you download the full Dart project as a ZIP on paid plans (from Basic, ~$39/mo), and you can keep building it in a real IDE. Bubble has no source-code export at all — you can take your data but never the application. That single difference is the spine of this comparison.
- Q03Does FlutterFlow need Firebase, and does Bubble include a database?
- FlutterFlow has no database of its own, so you connect Firebase (Firestore) or Supabase and manage it yourself. Bubble includes its database, workflows, and hosting in one platform. FlutterFlow trades all-in-one convenience for flexibility and ownership; Bubble trades ownership for a single system with nothing to assemble.
- Q04FlutterFlow vs Bubble: which is cheaper to scale?
- It depends on the axis. Bubble bills Workload Units, so a busy app's cost climbs with traffic. FlutterFlow bills per editor seat with no runtime meter, but you pay Firebase/Supabase and app-store fees separately. A high-traffic app is often cheaper on FlutterFlow's model, provided you can run the backend it requires.
- Q05Can I migrate a Bubble app to FlutterFlow?
- Not directly — there's no importer, and the two build very differently (web-first visual runtime vs native Flutter on an external backend). You'd rebuild the UI and logic and stand up a Firebase/Supabase backend. If you're rebuilding anyway, that's the moment to weigh a clean codebase you own outright against another platform.
