Felgo vs. GraalVM

Felgo shines in rapid prototype development and fast iterations. It also has a very short learning curve compared to many other technologies that promise "code once, deploy everywhere." It is not appropriate if you are not willing to mess with the licensing related to Qt but I am still waiting for a clear answer on my doubts from the Felgo team.

Its well fit for the environment where applications are written in programming languages supported by GraalVM. It's [a] very powerful and reliable, high-performer Java Virtual Machine that provides the Java Development kit i.e JDK that has the ability to compile the Java apps ahead of time. Maintenance of this tool is simple and it [increases] the efficiency of the product since it requires few resources.

• Ready available solutions for all platform mobile app development.
• Live hot reloading of UI and other advance controls by Felgo implemented in Qt.
• Using Qt underneath provides an opportunity to developers to use it in all kind of sectors like embedded devices, mobile apps, desktop apps, games etc.

• Best performance of applications
• High efficiency of applications
• Reduced hardware requirements
• Lesser consumption of resources
• Universal support to multiple programming languages
• Reduced size of applications
• Creation of virtual images for testing on Android and iOS mobile operating systems
• Creation of native images
• Excellent support
• Documentations are detailed enough to learn and use easily
• Easy to use

• QML component / C++ code with hot reload feature.

• It should be possible to use GraalVM EE to distribute native images of JavaFX applications for mobile platforms, especially for Apple platforms.
• Native Images are a game changer. However, compiling complex applications can be a pain. Better support for an improved transition process are a must.

I am happy with the constant feedback that I am receiving from the team. Although most of it is marketing related, there are some interesting and valuable materials that they have been pushing to ease my learning.

The quality of the documentation and the ease of use may be some important values to take into account.

We believe that the agility that we have acquired until now for developing apps for our business cases give this framework an important lead.

As with any product, Felgo has some edges to it, but from our past experiences evaluating "code once, deploy everywhere" platforms, we were really surprised at how fast the team went from exploring, into playing and presenting prototypes in very little time.

The dev cycle is really fast as I can get an almost instantaneous feedback on the changes that I make. And it is refreshing to see how I am able to target several platforms at once.

The javascript plus QML combination made it really easy to pick up for me and I am certain sure that many devs can migrate from Web only into multi-platform in a fast manner.

And there is also the possibility to implement C++ code if the need arises to support and bridge native libraries.

Like all Oracle tools, you can find a lot of documentation and also write down your questions in a forum. Sadly I don't see too many users so far but I hope it'll keep increasing and in a short period we will have more information and ofc issues fixed. So far, everything I needed I could find easily.

The helpful, responsive customer support. In contrast to frameworks like Flutter, you can count on a professional team that can help you out if needed

GraalVM is at the top when it comes to executing Java applications in terms of speed. With its amazing fast ahead of its time compiler it helps in reducing the startup time of the applications. Also, the overall performance of the product is increased and reduces the latency as well. It supports multiple languages such as Groovy, Ruby, Javascript, R, Python, Scala, Java, Clojure, and many more.

• Financial: Increased Java container count on the same hardware.
• Performance: Decreased cold start time for container startup.
• Training: Adopting GraalVM has a learning curve. This requires investment in time and resources. The benefits come through re-evaluating our current deployments for optimization.
