- You need clearly documented enterprise compliance posture (e.g., SOC 2 Type II, ISO 27001) and vendor-provided public documentation is insufficient
- FlutterFlow publicly states SOC 2 Type I, but Type II / ISO details were not confirmed in accessible sources; for regulated industries, this is a common “stop sign” unless validated via vendor security package. ([docs.flutterflow.io](https://docs.flutterflow.io/misc/security))
- Your app is expected to become highly complex quickly
- Multiple sources describe a “complexity cliff” where you start building workarounds, custom code, or maintain exported Dart—reducing the benefits of the visual builder. ([reddit.com](https://www.reddit.com/r/FlutterFlow/comments/1piuyk1/what_is_going_on/?utm_source=openai))
- Your team is non-technical and expects true no-code
- Reviews repeatedly emphasize it functions as low-code in practice (custom code and deeper technical understanding become necessary). ([g2.com](https://www.g2.com/products/flutterflow/reviews))
- You cannot tolerate tooling slowness/bugs in the builder
- “Slow and buggy UI” and “editor becomes a little slow” appear in reviews; if your delivery depends on consistently fast tooling, plan a proof-of-concept with your target app complexity. ([capterra.com](https://www.capterra.com/p/249489/FlutterFlow/reviews/))
- Known limitations from reviews/community
- Editor performance degradation as projects scale ([g2.com](https://www.g2.com/products/flutterflow/reviews))
- “Low-code” reality: advanced features require custom code / exported-code editing ([g2.com](https://www.g2.com/products/flutterflow/reviews))
- Integration rough edges: API/auth gaps and tricky database connections mentioned by reviewers ([capterra.com](https://www.capterra.com/p/249489/FlutterFlow/reviews/))
- Roadmap / future features
- Some reviewers reference roadmaps suggesting query/data improvements “this year,” but this is not a firm commitment or an audited delivery plan. ([g2.com](https://www.g2.com/products/flutterflow/reviews))
- Security/compliance gaps
- SOC 2 Type I is stated; broader certifications and enterprise controls are not clearly documented publicly in accessible sources and should be validated in diligence. ([docs.flutterflow.io](https://docs.flutterflow.io/misc/security))
