The short version

  • Each has a real cost: FlutterFlow downloading your own generated code requires the Pro tier, so on cheaper plans you can build the application but cannot take it with you, which is precisely the reason most buyers chose the product.; Mendix the platform fee explicitly excludes compute and infrastructure costs, so the real all-in bill is the subscription plus a separate, less predictable cloud hosting charge.
  • They diverge on capability: FlutterFlow covers Flutter code generation, Mendix covers Visual app and process modelling.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

FlutterFlow

  • A founder building a genuine cross-platform mobile app rather than a web formnot Mendix
  • Prototyping an application that an in-house Flutter team will later take over as codenot Mendix
  • Agencies delivering client mobile apps on a fixed budget where handing over source is contractualnot Mendix
  • Internal apps that must be installed from the app stores rather than opened in a browsernot Mendix

Mendix

  • A Siemens industrial software customer extending into application development on a platform already inside its vendor ecosystemnot FlutterFlow
  • A company building exactly one production app that wants the lower One App tier rather than paying for unlimited apps it does not neednot FlutterFlow
  • An enterprise standardising on Mendix across many departments where the Unlimited Apps tier amortises wellnot FlutterFlow
  • A team wanting to evaluate low-code at zero cost before committing to a paid production tiernot FlutterFlow

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

FlutterFlow

  • Downloading your own generated code requires the Pro tier, so on cheaper plans you can build the application but cannot take it with you, which is precisely the reason most buyers chose the product.
  • The output is Dart and Flutter, so the escape hatch only helps an organisation that already has or is willing to hire Flutter developers; for a non-technical buyer the exported code is unusable.
  • Once logic moves into custom functions and custom widgets, the visual editor becomes slower than writing the same code by hand, so the tool works against you at exactly the point the project gets serious.
  • The browser editor gets sluggish on large projects, with preview and build times that lengthen as page and component counts grow, which is felt daily by teams past the prototype stage.
  • There is no backend; Firebase or Supabase modelling, security rules, indexes and their bills are entirely your responsibility, so a FlutterFlow application is always at least two subscriptions and two skill sets.

Mendix

  • The platform fee explicitly excludes compute and infrastructure costs, so the real all-in bill is the subscription plus a separate, less predictable cloud hosting charge.
  • The jump from a free or One App tier to Unlimited Apps is a large discrete price step (roughly 918 to 2,295 euros a month at published starting rates), not a gradual scale-up, which punishes a team that grows from one app to two.
  • Being a Siemens business unit means Mendix roadmap priorities can be shaped by Siemens' broader industrial software strategy rather than purely by low-code market demand.
  • Deployment flexibility across Mendix Cloud, Azure, Kubernetes and SAP BTP is a strength on paper but means the actual infrastructure cost and complexity vary significantly by choice, complicating like-for-like vendor comparisons.
  • Premium-tier features and enterprise governance capabilities are quote-only, so a buyer cannot fully compare Mendix's top tier against OutSystems or Appian without entering a sales process.

Answered from the vendors’ own pages

FlutterFlow: Can I export the code?

Yes, on the Pro tier and above. Lower tiers can build and preview but not download the Flutter project.

Mendix: What is the difference between One App and Unlimited Apps?

One App licenses a single application in production; Unlimited Apps covers any number of apps under one subscription, at a materially higher starting price.

FlutterFlow: Do I need to know how to code?

Not to build a straightforward application. You will need Dart for custom functions, for anything unusual, and for maintaining the exported project afterwards.

Mendix: Does the licence include hosting?

No. Mendix states explicitly that compute and infrastructure resources are billed separately from the platform licence, regardless of deployment target.

FlutterFlow: Does it include a database?

No. FlutterFlow builds the client. Data lives in Firebase, Supabase or your own API, and those costs and design decisions are separate.

Mendix: Who owns Mendix?

Siemens, which acquired Mendix in 2018 and runs it as part of its industrial software portfolio.
