Exploring 15 Powerful Flutter Alternatives

Flutter is an open-source app development framework created by Google to build natively compiled mobile, desktop, and web applications from a single Dart codebase. It has grown rapidly in popularity due to fast performance, an expressive UI framework, and simplified cross-platform development.

When initially released in 2017, Flutter promised to resolve many notoriously difficult aspects of mobile development, from UI design to native builds to platform inconsistencies. For many developers, Flutter has delivered by rendering beautifully animated UIs that run at high speeds through compiled native code instead of JavaScript bridges.

However, Flutter also has some limitations that motivate the need for alternatives:

• First, as a relatively young framework, Flutter suffers fragmentation across OS versions, platforms, devices, and form factors that can cause subtle issues and bugs requiring workarounds.
• Secondly, Flutter’s reliance on Dart can present initial learning curve barriers relative to alternatives leveraging languages and tools developers already know.
• Finally, some developers feel Google may deprioritize Flutter over time as they have other developer products if it fails to achieve further escape velocity.

Therefore, even with Flutter maturing rapidly, exploring alternatives merits consideration to determine what other cross-platform development approaches offer relative to a company’s or developer’s specific needs and constraints. Progress never stops, so assessing options outside Flutter helps identify hedge opportunities and ideas for how Google might continue advancing Flutter’s capabilities.

15 Flutter Alternatives

1. ASP.NET Core

ASP.NET Core is an open-source and cross-platform framework for building modern cloud-enabled web apps on Windows, Mac, and Linux. One unique capability ASP.NET Core introduces relates to scalability. The framework provides native integration with cloud platforms like Azure that allow web apps to scale up or out to potentially even millions of users with no code modifications at all — in other words, it allows horizontal and vertical scaling through configuration changes instead of software changes. This scalability comes through ASP.NET Core’s support for load balancing, geo-distribution, staged rollouts, and not needing to run or compile the app locally to publish.

Advantages

• Open-source and cross-platform: Apps can run on Windows, Mac, and Linux
• High performance: Optimized for web workloads and handles significant traffic
• Flexible cloud hosting: Integrates with Azure but can be hosted anywhere
• Rich ecosystems: Lots of .NET libraries and NuGet packages available
