The short version

  • Each has a real cost: .NET MAUI its release and support lifecycle is tied to the underlying .NET version, so a team on an odd-numbered .NET release faces a support cutoff roughly every eighteen months and must budget upgrade work accordingly.; Frappe the framework is strongly opinionated: its own ORM, templating and job queue mean general Python and Django experience transfers only partly, and onboarding a new developer takes weeks rather than days.
  • They diverge on capability: .NET MAUI covers Single C# and XAML codebase, Frappe covers DocType modelling.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

.NET MAUI

  • Its release and support lifecycle is tied to the underlying .NET version, so a team on an odd-numbered .NET release faces a support cutoff roughly every eighteen months and must budget upgrade work accordingly.
  • Platform-specific control styling and native look-and-feel have historically needed more manual work and workaround packages than Flutter delivers out of the box.
  • macOS and desktop support are less mature than the iOS and Android targets, so teams wanting a strong Mac app experience often still reach for native AppKit or a dedicated tool.
  • The talent pool of mobile developers fluent in MAUI specifically is smaller than for Flutter or React Native, even though C# itself is common.
  • Third-party control libraries such as Syncfusion and Telerik fill real gaps in the built-in component set, meaning a serious app often carries an additional commercial licence cost despite the framework itself being free.

Frappe

  • The framework is strongly opinionated: its own ORM, templating and job queue mean general Python and Django experience transfers only partly, and onboarding a new developer takes weeks rather than days.
  • The developer pool is small and heavily concentrated in India, so hiring Frappe experience elsewhere is slow and expensive relative to mainstream stacks.
  • Documentation is uneven in depth and lags behind releases in places, so real answers often come from reading the source or the community forum.
  • Major version upgrades of the framework have historically broken custom apps that reach past the DocType layer, so bespoke code carries a recurring maintenance cost at each upgrade.
  • Frappe Cloud recommends against its cheapest Hetzner-backed option for mission-critical production, so the headline $5 entry price is not the price of a production-grade deployment.

Answered from the vendors’ own pages

.NET MAUI: Is .NET MAUI really free for commercial apps?

Yes. It ships under the MIT licence as part of the free .NET SDK, with no separate mobile licence fee from Microsoft.

Frappe: Is Frappe the same as ERPNext?

No. Frappe is the framework; ERPNext is the ERP application written on it. You can run Frappe without ERPNext to build your own applications.

.NET MAUI: Is this the same as Xamarin?

It is the successor. Xamarin.Forms was retired in 2024 and Microsoft provides migration tooling from it to MAUI.

Frappe: What licence is the framework under?

MIT, which is permissive and imposes no obligation to publish your changes, unlike the AGPL used by several open source ERP rivals.

.NET MAUI: How long is each .NET version supported?

Even-numbered releases get Long Term Support (around three years); odd-numbered releases get roughly eighteen months, and MAUI follows that same .NET release cadence.

Frappe: Can I pay in rupees?

Yes. Frappe Cloud publishes the same plans in Indian rupees, ₹410 a month for sites and ₹3,600 for servers, rather than converting a dollar price at checkout.

Frappe: Do I have to use Frappe Cloud?

No, self-hosting with bench or Docker is fully supported and free. Frappe Cloud is a convenience purchase, and it funds the open source work.
