Felgo vs. GraalVM

It is a very good tool for making all types of mobile and web applications once you know how to use it. It allowed us to realize several application concepts, such as currency converter, pregnancy monitoring, QR code flash for product evaluation. No need for native SDKs, Build in and Install from Cloud with the Felgo Build Server.

If you want to have a cool VM, don't spend too much memory and mainly being multilanguage go ahead. Be aware there are some points that can be improved like a couple of languages are not accepted so far. Like used to, it's easy to use and you can find a lot of information regarding the tool so if you need to do something fast, it's a good choice.

• 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.

Incentivized

• 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

Incentivized

• 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.

The support we received when porting legacy applications from the GraalVM team and community was commendable. We were able to get assistance in introducing alternatives for the libraries we were using where appropriate. GraalVM support was also able to help us with some configuration options we were stuck with for configuring deployment environments on AWS compute.

As I was already a C++ and Qt developer, Felgo was obvious choice over other tools. Also its cross-platform solutions for mobile apps and Qt's ability to provide cross-platform tool for all other devices makes this perfect choice.

The reason why we had to select GraalVM one is [a] cutting-edge compiling technique, GraalVM is well operated in the Environment of Open JDK, which speeds up the execution of Java programs. GraalVM makes creating packages and native apps simpler, and this improves distribution. It also brings native image support [that] makes compilation and distribution easy and effective.

Incentivized

• Development cost became low
• Easy to learn
• created well performed cross platform application

• 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.
