The short version
- Only FlutterFlow has a free tier, so it costs nothing to try first.
- 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.; Stacker there is no source export and no self-hosting, so leaving means rebuilding the entire interface and permission model elsewhere, even though the underlying records remain yours.
- They diverge on capability: FlutterFlow covers Flutter code generation, Stacker covers Per-record permissions.
- Prices and features above were last checked on 31 August 2026.

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.
Stacker
- There is no source export and no self-hosting, so leaving means rebuilding the entire interface and permission model elsewhere, even though the underlying records remain yours.
- Performance is bounded by the data source, so an Airtable base near its row limit or an API under rate limiting produces a slow portal that no amount of Stacker configuration will fix.
- Pricing distinguishes internal editors from external portal users, so a portal that succeeds by adding hundreds of light-touch external users can end up costing more than the internal system it fronts.
- Custom logic is limited to the actions and conditions the builder exposes, so anything resembling a calculation engine or a branching multi-step approval hits a wall and needs an external automation tool bolted on.
- It is a portal and CRUD tool by design, with no offline mode, no native mobile application and no real reporting layer, so it will not be the only system a growing operation runs.

Questions people ask
- Is FlutterFlow or Stacker better?
- Neither clearly leads. FlutterFlow starts at Free and Stacker at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, FlutterFlow or Stacker?
- FlutterFlow has a free tier; the other does not. Paid plans start at Free for FlutterFlow and On request for Stacker.
- Does FlutterFlow or Stacker run on more platforms?
- FlutterFlow runs on Web, iOS, Android. Stacker runs on Web.
- Can I use FlutterFlow for free?
- Yes. FlutterFlow has a free tier, so you can try it without paying. Stacker starts at On request.
- What is FlutterFlow best used for?
- FlutterFlow is most often used for a founder building a genuine cross-platform mobile app rather than a web form, prototyping an application that an in-house flutter team will later take over as code, agencies delivering client mobile apps on a fixed budget where handing over source is contractual, internal apps that must be installed from the app stores rather than opened in a browser. Of those, a founder building a genuine cross-platform mobile app rather than a web form and prototyping an application that an in-house flutter team will later take over as code are not what Stacker is typically brought in for.
- What can FlutterFlow do that Stacker cannot?
- FlutterFlow covers Flutter code generation, Firebase and Supabase integration, API and GraphQL calls, Custom code. Stacker covers Per-record permissions, External user portals, Live connection to the source, Page and layout builder.
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.
Stacker: Where does my data live?
In the source you connect: Airtable, Salesforce, HubSpot, Google Sheets or your own Postgres. Stacker reads and writes to it rather than becoming the system of record.
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.
Stacker: Can I export the app if I cancel?
No. The data stays in your source system, but the interface, permissions and workflows are Stacker configuration and do not come with you.
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.
Stacker: Is it suitable for hundreds of external users?
Technically yes; check the pricing arithmetic first, because external portal users are charged separately and that is where the bill grows.
Stacker: Will it replace Airtable?
No, it sits in front of Airtable. If the base itself is at its limits, the fix is moving the data to Postgres rather than changing the portal.
