MonoDevelop

Top Pro

Top Con

Bad formatting

MonoDevelop doesn't offer much in terms of autocompletion and code formatting. Most of the time the automatic formatting that MonoDevelop does is annoying and not really compliant with C# guidelines. See More

Easy to use

Easy to make compiled native apps. See More

Top Con

No Android support

They plan to eventually support Android, but for now, they only support iOS. See More

PerfectIoMatuaKore's Experience

Poor Android support. Buggy See More

Specs

Platforms:Windows, Linux, Mac, Pi, Web,iOS

Visual GUI Builder:Yes

Top Pro

Compiled apps are a major pro. The community is very helpful.

Top Con

Too many bugs

A lot of bugs reported by developers aren’t and won’t be solved. See More

Roman Varas's Experience

Very easy to learn, quite powerful once you learnt it See More

Top Pro

Very easy to learn, cross-platform compilation often requires just a click

More advanced features are doable with declared, great third-party plugins (Monkeybread & Einhugur are highly recommended), not a subscription. On the downside bugs can linger for years, some features not as complete or powerful as they should be, some expected features (eg calendar control) not there as community or third party provide solutions (so no need to implement and no wish to compete). See More

Top Con

Targets not always 100% percent compliant with platform standards

What this means is that to get a perfect match for MacOS or Windows or Linux you will have to get into Declares or use 3rd party plugins to get them looking identical to what you'd get with the default platform IDE's (i.e. xCode for MacOS, Visual Studio for Windows). Xojo does the lowest common denominator for controls so it's a bit more work to make each target look perfect (or as perfect as possible). See More

Oliver Osswald's Experience

I used MS Visual Studio to create Windows desktop apps (C#, Dot.Net 2.0) and now I am mainly using Xojo to create native desktop apps on macOS, Windows and Ubuntu Linux. I also use Xojo to create standalone webservices running on Ubuntu servers, without need for apache or nginx. See More

Top Pro

If you have bought a license you can use it for the rest of your life

You bough a LICENSE. See More

Top Con

Small company so can be down or bought at any time

Gavin's Experience

I've used Xojo for over 20 years. In fact, I've built my career on it. I know a number of other languages, including Swift, but I always come back to Xojo to make professional, powerful native apps, quickly. When you learn the IDE and language, you can transfer much of these skills from one target to the next. For example, you can make Windows and Mac apps and then reuse much of these skills to make Web or iOS apps. It's really easy to get started and the product will grow with you. I can honestly recommend it! See More

Top Pro

Standalone dev tool, you don't need a cloud to use it

Top Con

Subscription-based/Not free

Using this product you're betting the company will still be around. If they get bought out by an enterprise that wants to use the tech internally, all they need to do is stop offering subscriptions and suddenly you're scrambling to rebuild your entire app on other technology. See More

kcully's Experience

Easy to get started. Powerful enough that you never reach the technology wall. Great community. Great company to work with BTW. See More

Top Pro

Free to try, you pay only when you compile for a platform

You pay for one year of updates, then your license still works but you don't get more updates. See More

Top Con

Limited resources for learning available

There are far too few learning resources available. Overpriced options don't contain up-to-date information. See More

LogicalToci's Experience

I get to make excellent looking professional applications with ease. Being a native app on each platform makes the app look feel correctly for the end user. See More

Top Pro

Easy to get in touch with the developers

SmartPrabhasa's Experience

easy to use, but powerful in the longer run. real multi platform app generated. dev team is too small IMHO so evolution is quite slow, but there is still so much to be improved. love it. See More

Top Pro

It's been alive since 1998

Xojo has been going since 1998, through different OSs, different architectures and different trends. Many other languages and IDEs have come and gone in that time. See More

Bob Keeney's Experience

I've been using Xojo for over 16 years. Xojo does a great job making consistent cross-platform (Mac, Windows, Linux, Raspberry Pi) desktop applications and for the most part it's really is a just a checkbox to create native apps for each target. You can also create Mac, Windows, Linux, Raspberry Pi console apps. You can also easily create web apps (not sites!) that work on Mac, Windows, Linux, and Raspberry Pi using much of same code base as desktop/console. Xojo also does iOS applications too. It's by far the youngest target in the product and currently requires using a different framework. The company is slowly migrating the framework to match the other targets. They are currently working on Android but no release date has been set. Having both iOS and Android will make the mobile offering much more complete. See More

Top Pro

Nice to have back end code that can be shared for Web apps as well as Desktop apps

SkillfulPeckols's Experience

Very powerful and an extremely helpful community See More

Top Pro

Running a debug instance of your app on Windows while the IDE is on Mac is a great way of working.

You can have the Xojo IDE running on macOS with a target build of your app running on a Windows computer, the two computers networked to each other. This lets you build on the Mac launch the app on Windows, then watch the code execute from the Mac, pausing to inspect or modify variables, without interfering with the IDE on the Windows computer. No lost or confused events that can happen when you interrupt a running app to do this. See More

ComposedAnubis's Experience

Intuitive UI and language, compiles solid modern apps, devoted staff, welcoming community See More

Top Pro

Their forum is busy and extremely responsive.

Everyone on the forum is very engaged, opinionated, and generous with their expertise. I've asked many questions over the years and there is always a reply the same day, sometimes within minutes. See More

All of their staff are available on their forum, including the CEO. See More

DynamicSakpata's Experience

I had been using VB6 and needed to build a Mac version of my app. Converting to Xojo was pretty painless, and I'm also using it to build apps for my web site. Next up are apps for iOS. Their pricing is reasonable (I'm leery of free), and their annual developer conference is terrific. See More

Top Pro

Nice to have back end code that can be shared for Web, Desktop & iOS apps

React Native

Top Con

If core team doesn't use a certain feature, it's not developed

Whenever there's functionality you need that they don't use in their apps, it's not going to get developed by them, even if it's obvious it should be in the core. They always say to either submit a PR or create a separate module. See More

Top Con

Steep learning curve

React Native is not the most beginner-friendly framework for creating mobile apps with JavaScript. It requires that the developer know React, which is known to have a steep learning curve. See More

Xamarin

Top Pro

Lets you build on existing .NET knowledge

If you have a background in Windows development, chances are you already know WPF and .NET. Xamarin and Xamarin Forms extends this to other major platforms. And you can reuse existing .NET libraries and packages. See More

Top Con

Specs

Mobile targets:Android, iOS, Windows Phone

Languages:C#

Top Pro

Cross-platform

Apps built with Xamarin can run natively on Android, iOS and Windows Mobile. Xamarin compiles the same C# or F# codebase to native code that runs on several platforms. See More

Top Con

Slow to implement new features; must wait 1+ month to be able to access it

Top Con

It feels unfinished

Shouldn't have a paid license; QML has very strong foundations, very easy to extend and customize but the default controls (especially for desktop) look awful. Digia didn't have the strength to finish it: the default Tabs control has a really unintuitive API and looks very raw (the tabs don't even have the close (x) buttons. Missing controls for treeview or gridview...So much wasted potential, it's a shame... See More

Kotlin

Top Pro

Easy to learn if you have prior programming experience

Kotlin's syntax is extremely easy to understand. The language can be picked up in a few hours just by reading the language reference. See More

Hosch Nok's Experience

Kotlin is a real multi purpose language, since you can even compile to js or web assembly. It is mainly used for ios and android applications. The developers are the creators of intellij IDE, which is probably the only IDE, which can afford to offer yearly subscriptions. However, the community edition is free and Android projects will be created with Kotlin by default. So you have the best IDE coupled with a deeply integraded programming language, which compiles down to native code. See More

Specs

Price:Free, Open Source

Current stable version:1.3

Site:http://kotlinlang.org

Top Pro

Officially supported for Android development

Starting with version 3.0 of Android Studio, Kotlin support will be built-in. This means that it's now easier than ever to use Kotlin for existing Android projects or even start writing Android apps only with Kotlin from scratch. This also means that Kotlin and Kotlin plugins for Android Studio will be fully supported in the future and their likelihood of being abandoned is quite small since Google is fully embracing the language for their Android ecosystem (alongside Java and C++). See More

Top Pro

Great tooling support

Since Kotlin is made by Jetbrains (the developers of IntelliJ IDEA) so it stands to reason that the IntelliJ support for Kotlin is also great. Besides that, Kotlin also works well with existing Java tools such as Eclipse, Maven, Gradle, Android Studio, etc... See More

Java application

Top Pro

Provided the machine already has Java. See More

Top Con

Not really cross-platform

Applications are compiled to a single platform—the Java Virtual Machine. But the same can be said about .net, Delphi, Javascript or Python set of libraries. See More

BraveMastoratia's Experience

Java is a great tool to build server side or local apps. I use it regularly for nearly 20 years now. See More

Top Pro

Mature

Top Con

Client still needs Java

For Java applications to run on a device, the device needs to have a Java Virtual Machine installed. This can be mitigated by providing java runtime with the app or transpiling to another language (GWT with javascript for instance) See More

Top Pro

Lots of available languages: Kotlin, Scala, Clojure

Top Con

Reputation for being bloated and insecure

Java apps have a poor security reputation and are often slow. But security problems exist in other platforms. Javascript and Python are slower than Java but are popular so speed is not always the only important thing. See More
