The short version

  • Each has a real cost: Fillout the Business plan is marketed with unlimited responses but the fair use policy names thresholds of 30,000 submissions a month, 250,000 in total, 500 forms per account and 50 GB of uploads a month, above which the vendor may limit or suspend features, so unlimited means unmetered rather than uncapped.; 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.
  • They diverge on capability: Fillout covers Unlimited seats and forms, FlutterFlow covers Flutter code generation.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

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

Where each one falls short

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

Fillout

  • The Business plan is marketed with unlimited responses but the fair use policy names thresholds of 30,000 submissions a month, 250,000 in total, 500 forms per account and 50 GB of uploads a month, above which the vendor may limit or suspend features, so unlimited means unmetered rather than uncapped.
  • EU data residency begins on the Team plan at 250 USD per month, more than three times the Business price, and is not applied automatically; you must upgrade and then raise a support request to be moved.
  • The Team plan is hidden behind a secondary tab that does not render without interaction, so buyers reading the pricing page see Business at 75 USD as the top self-serve tier and only discover the 250 USD step when they ask for single sign-on or EU hosting.
  • The enterprise marketing page lists hosting in the United States, EU, United Kingdom, Australia and Canada, but the security documentation and subprocessor list name only the United States and the EU, so three of those five regions should be confirmed in writing before they are relied on.
  • The vendor is SOC 2 Type 2 but claims neither ISO 27001 nor HIPAA anywhere in its documentation, and it is angel-funded with no disclosed institutional round while the parent company now trades as Zite and ships a separate AI application builder.

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.

Answered from the vendors’ own pages

Fillout: Are seats really unlimited?

Yes. The vendor states there are no per-seat charges on any plan, including Free, and forms are unlimited too. Responses per month is the only meter below the Business tier.

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.

Fillout: What happens when I exceed my response quota?

Nothing breaks. Forms keep collecting, and you can upgrade, buy bulk submissions or wait for the monthly reset.

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.

Fillout: Can I host respondent data in the EU?

Only from the Team plan at 250 USD per month, and only after contacting support to switch. Note that email and payment subprocessors remain in the United States regardless.

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.

Fillout: Is the Business plan really unlimited responses?

It is unmetered, not uncapped. The fair use policy names roughly 30,000 submissions a month as the point at which the vendor may intervene, so treat that as the practical ceiling.
