The best dev tool I've come across in my entire development career (+30 years) **Rating:** 5.0/5.0 stars **Reviewed by:** Jean-Marc L. | CEO, Small-Business (50 or fewer emp.) **Reviewed Date:** December 05, 2023 **What do you like best about Felgo?** We like: the power and versatility of Qt, the Felgo library of ultra-productive components, the Felgo plugins, the Felgo doc, the Felgo cloud builds service, the always responsive and efficient Felgo support, and of course the efficiency and ease of use of the QML language coupled with Javascript (while being able to call on C++ as reinforcement in complex cases). With my company AppliStudio and its label Kovalia we have been trusting Felgo for years. We have successfully and satisfactorily developed a dozen applications (mobile, desktop, embedded, etc.) for our customers and our in-house productions. We sometimes use other development frameworks, but when we have the choice, we prefer Felgo for its great possibilities, efficiency and versatility. **What do you dislike about Felgo?** As with all development tools, we encounter some small bugs in some libraries and some small errors in the doc, but nothing abnormal! And since the support responds well and patches always arrive pretty quickly, there's not much we don't like about Felgo. **What problems is Felgo solving and how is that benefiting you?** Felgo allows us to tackle just about any software creation scenario on many media, so we don't need to use too many different technologies to develop effectively. There is still some progress to be made to make web export (with WebAssembly) more affordable and widespread, but it's on the right track from what we've seen ### 2. helps qml visualization significantly **Rating:** 4.5/5.0 stars **Reviewed by:** Robert G. | Senior Manager, IT M&A Program Delivery , Small-Business (50 or fewer emp.) **Reviewed Date:** November 16, 2024 **What do you like best about Felgo?** how it can help testing visuals very quickly. **What do you dislike about Felgo?** Installation is diffcult and time consuming. **What problems is Felgo solving and how is that benefiting you?** quick test qmls ### 3. Easy Cross-Platform framework **Rating:** 5.0/5.0 stars **Reviewed by:** Behzad H. | Researcher PHD Student, Enterprise (> 1000 emp.) **Reviewed Date:** August 07, 2024 **What do you like best about Felgo?** Live Code Reloading, easy for building across different platform **What do you dislike about Felgo?** Smaller community, performance overhead with huge size of install files **What problems is Felgo solving and how is that benefiting you?** compiling on different platforms ### 4. Best way for C++/Qt developers to develop mobile apps **Rating:** 5.0/5.0 stars **Reviewed by:** James H. | Software Engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** October 02, 2022 **What do you like best about Felgo?** For any C++/Qt developers looking to make mobile applications, I'd highly recommend Felgo. For me, QML is a familiar and effective way to create user interfaces. Felgo allows me to easily create mobile applications that look native. Just like Qt, the documentation is great. There are a good amount of examples as well. With the Felgo Live client, it is easy to test your apps on different devices, and it even has a hot reload capability. **What do you dislike about Felgo?** I had a few hiccups getting started. I had some issues trying to deploy to my mobile device for testing, but I I was able to resolve them by reading through the console errors I was getting (ended up being related to the version of the JDK I had installed). **What problems is Felgo solving and how is that benefiting you?** Felgo allows me to write a single code base using technologies (Qt/QML) that I am familiar with and deploy a native-looking application to several different device types (Windows, Android, IOS, etc.). ### 5. Very easy framework **Rating:** 5.0/5.0 stars **Reviewed by:** Suraj K. | Software Associate, Computer Software, Small-Business (50 or fewer emp.) **Reviewed Date:** February 23, 2023 **What do you like best about Felgo?** The framework is easy to learn, with the documentation & training materials. The easy use of QML and the best C++ libraries as a back-end. The helpful, responsive customer support **What do you dislike about Felgo?** Nothing I have found as of now. Experimenting all the things to get best out of it. **What problems is Felgo solving and how is that benefiting you?** Create apps that run on multiple platforms & devices with a single code base. It only takes a second to reload Qt, QML, and JavaScript code on any of my devices at the same time. ### 6. Felgo is the modern way to create your apps **Rating:** 5.0/5.0 stars **Reviewed by:** MARTIN M. | Senior System Administrator, Small-Business (50 or fewer emp.) **Reviewed Date:** February 04, 2022 **What do you like best about Felgo?** It has all the models you need to create your mobile applications. Applications automatically generated for Android and Apple and therefore no need for multiple codebases. **What do you dislike about Felgo?** To create your hardcoded other than the scripted application you will need to use C++ which has a tough learning curve. The tool is also embedded into Qt IDE instead of having its own custom installation for Felgo only. **Recommendations to others considering Felgo:** Felgo is worth learning and using. The QML which is the language it uses to create your awesome mobile application is easy to learn since it is based on JavaScript. It also has all the models you need. I really recommend this. **What problems is Felgo solving and how is that benefiting you?** I am building a mobile app that will be used mostly for android users although am not fearing since Felgo will help me use the same code base to build for Apple users. ### 7. Fast and Efficient! **Rating:** 4.0/5.0 stars **Reviewed by:** Akram S. | Computer Science Student, Small-Business (50 or fewer emp.) **Reviewed Date:** December 20, 2021 **What do you like best about Felgo?** Significantly increased development speed due to out-of-the-box APIs & integrations that allow reusing code across platforms. **What do you dislike about Felgo?** Lack of online teaching material on the web, due to its unpopularity. **Recommendations to others considering Felgo:** You have the whole world of Qt at your hands when using Felgo. If you search for answers online, also search for Qt-related answers and resources; you can use them with Felgo as well. **What problems is Felgo solving and how is that benefiting you?** With Felgoo on top, the Qt framework becomes much more powerful and allows me to turn around much more complex, time-consuming, multi-platform projects. ### 8. Go Felgo! **Rating:** 5.0/5.0 stars **Reviewed by:** Franck L. | Software Engineering Manager Thales Optronic (TOSA), Small-Business (50 or fewer emp.) **Reviewed Date:** March 01, 2022 **What do you like best about Felgo?** - Ease of use. - Multiplatform support. - Lots of high level functionalities. - No need to reivent the wheel. **What do you dislike about Felgo?** - The "Live" window that pops up all the time. **What problems is Felgo solving and how is that benefiting you?** - Building truly cross-plaform UI, with device independent pixels (Desktop, Android, iOS). ### 9. Very simple and friendly with a great team behind **Rating:** 5.0/5.0 stars **Reviewed by:** Izcóatl Armando E. | Associate CIO, Small-Business (50 or fewer emp.) **Reviewed Date:** February 06, 2021 **What do you like best about Felgo?** I was first attracted into getting to the "code once, deploy everywhere" paradigm that is part of their attention grabber. But I got really in love into the fast development cycle experience that I discovered. I thought at first that my learning curve would be a lengthy one. But I am really surprised at how fast the development cycle is and how far I have gotten into creating prototypes in just a week after downloading and installing it. It reminds me of the way I was used to creating fast and attractive apps when I developed under Adobe Flash. 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. I am also 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. **What do you dislike about Felgo?** I believe that some points that are not so clear to me might be laying in the way that the Qt and QML related licensing models could intertwine with the projects that I am creating. It is not clear to me if there are additional fees or open-source licensing related constraints that must be taken into account to avoid compliance with the Qt licensing model. Of course, there are the many contact routes and emails that the team has sent to me and I am right now expecting for a more human-understandable way of approaching to licensing. There is also the way that the initial Splash Screen and loading phase that make the apps created feel like running in a container and not a real native experience. Although having this container framework seems to be true, I believe that a more sophisticated splash would help to better this odd feeling while the app loads. I am proud of having the Felgo logo starting my apps, but a more elegant solution would be in place. Or maybe there is something I must learn to change the way the app starts. Of course, there is the paid option where you can even remove the splash screen, but I don’t think this to be the real solution. **Recommendations to others considering Felgo:** Try it. As any other framework, it should adapt to your needs or you may better be well looking at some alternatives. I am really happy to have a framework that helps me make changes on the fly without having to republish into the different app stores. **What problems is Felgo solving and how is that benefiting you?** I am right now creating internal prototypes to test different ideas. This is really a game changer on how I was planning to go during the next days, learning. I am now productive and the Felgo demo apps are real and complete spaces to start from. ### 10. Terrible Tool - stay away. Looks great, but ultimately lets you down. **Rating:** 0.0/5.0 stars **Reviewed by:** Verified User in Broadcast Media | Small-Business (50 or fewer emp.) **Reviewed Date:** June 26, 2021 **What do you like best about Felgo?** Not much. Lots of pieces are almost great, but every piece has at least one big weakness. One of the support developers was really helpful. He's the only thing about Felgo that was worth it. **What do you dislike about Felgo?** Sales - Starting with the sales process - I was sold an Enterprise package with 5 hours/month. Then after a month they changed it to 5 hours total. And additional support hours were incredibly expensive. Most companies I've dealth with would at least attempt to correct the situation. Felgo did nothing. If you're a North American developer used to a straightforward sales process, stay away from these guys. They're a bait and switch operation. Tooling - The tooling is almost good. The quick turnaround from code to screen makes the initial development pretty quick. However, there are massive differences between what you see during the dev process and then what you get when you actually build the app. Cross-Platform - Similarly, the "cross-platform" features are almost great, but the flaws make it terrible. You'll wind up spending more time on the last little bit than you did on getting the app to Beta. Really, the widgets don't stay where they're supposed to, and there are lots of eccentricities that you can only learn if you pay for support. I just want to reiterate this is NOT a true cross-platform development platform. Documentation - the documentation is terrible. It looks great on the surface, but when you actually get into the details, much of the documentation is actually wrong. And there are significant pieces of documentation that are just missing. The documentation refers to the previous version of the tool -VPlay Engine - which should have been an obvious clue. Plugins - Having worked with 1/2 dozen other cross-platform mobile development frameworks, I expected the plugins to be "install and forget." However, many of the plugins require you to selectively copy and past dozens of files and directories by hand, then go into the project files and edit a number of configurations. It's the kind of thing I expect in an early stage, free, open-source project, but feels amateur in a product that carries a premium price. Cloud Build - They sell their Cloud Build process as a simple plug-and-play system. I love the idea, and some of the architecture ideas are great. However, in practice it's hard to use except in the simplest use cases. Push Notifications, for example, can't be built in to an OSX build. You wind up having to import the project into XCode, enabling Push Notifications, rebuilding etc. etc. So it's easier to just build in XCode from the start. Comparisons - compared to NativeScript, React Native, Flutter, and the other cross-platform frameworks I've used, I found Felgo to be a distant last. Parts of it are shiny and nice, but on the whole it was a huge disappointment. **What problems is Felgo solving and how is that benefiting you?** Unfortunately, Felgo didn't solve any problems - really it just slowed our project down by months. We wound up abandoning it 3 months in to the 12 month license. Once we pivoted to Flutter, the project got back on track and wound up under budget and ahead of schedule. ### 11. Hello Felgo **Rating:** 3.5/5.0 stars **Reviewed by:** Pooya E. | Co-Founder & Leader, Small-Business (50 or fewer emp.) **Reviewed Date:** July 23, 2021 **What do you like best about Felgo?** Cross platform GUI features Best integration with C++/QML **What do you dislike about Felgo?** If you love something then let it free. This product has a lot of potential and developers will love it if you add many new comfortable licenses. Also add some new tutorials about SEO for WASM specifically for web platform. **What problems is Felgo solving and how is that benefiting you?** Cross platform GUI for our cloud gaming platform. ### 12. Very good tool **Rating:** 5.0/5.0 stars **Reviewed by:** Koch F. | U, Small-Business (50 or fewer emp.) **Reviewed Date:** May 10, 2021 **What do you like best about Felgo?** We use Felgo to realize our mobile applications. We have created a mobile currency conversion application. It is an excellent application design tool that allowed us to quickly develop our project. The possibilities are almost endless and it was a real pleasure to work with this tool. **What do you dislike about Felgo?** Unfortunately it is not easy to use its own custom QML component / C++ code with hot reload feature. **What problems is Felgo solving and how is that benefiting you?** 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. ### 13. Felgo has shortened the development time for the application drastically. **Rating:** 5.0/5.0 stars **Reviewed by:** Gordon O. | Data analyst, Small-Business (50 or fewer emp.) **Reviewed Date:** June 18, 2021 **What do you like best about Felgo?** Real-time reloading of the user interface **What do you dislike about Felgo?** in my area of work, there are no dislikes **What problems is Felgo solving and how is that benefiting you?** I am creating a health management system for the management of the hospital. ### 14. Very useful and easy to use. **Rating:** 4.5/5.0 stars **Reviewed by:** Taher L. | Senior Software Engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** December 17, 2020 **What do you like best about Felgo?** Felgo live and plugins provided. All the necessary plugins and components are provided with good documentations which makes developers life easier. For rapid app/game development Felgo is preferred than other tools. **What do you dislike about Felgo?** Not enough examples are provided for the components developed by Felgo. If someone wants to use Felgo APIs then documentation is provided but usage is something requires reference of code. Also Felgo is running on older Qt which something needs to be provided with latest. **Recommendations to others considering Felgo:** For rapid development of cross platform Apps/Games felgo is one stop go solution. **What problems is Felgo solving and how is that benefiting you?** I'm developing game for mobile. Felgo provided all necessary plugins and it also has game engine which makes developer's life very easier. ### 15. Good job **Rating:** 5.0/5.0 stars **Reviewed by:** Lubos M. | SW architect, Small-Business (50 or fewer emp.) **Reviewed Date:** February 24, 2021 **What do you like best about Felgo?** How easy it is to create a mobile app. Don't need to set up the whole environment, just to leave the building app on the cloud. Very useful! **What do you dislike about Felgo?** I would like to try to build also an app for the Web (WebAssembly) on the cloud for free. **Recommendations to others considering Felgo:** Choose Felgo for a quick start of creating apps **What problems is Felgo solving and how is that benefiting you?** A better understanding of mobile development ### 16.
