I think C#'s WinForms is just as productive as Delphi's VCL. Unfortunately Microsoft abandoned it. Though I only used older versions of Delphi, so I don't know if recent improvements made it pull ahead.
However both have limitations in more complex areas, such as rich text (html), data binding and targeting mobile and desktop with a mostly shared code-base.
Two very different solutions. Autohotkey is a scripting language for specific tasks, while Delphi is unbounded in this sense. And Visual Studio has no RAD concept.
It is absolutely preferable in that sense. The web-esq interface approach is far harder than it needs to be for small applications with basic interfaces.
Glad to see Delphi still alive and being developed. I never used it much but I did use C++ Builder Explorer or something that they released for free probably 10+ years ago. Also does anyone remember Kylix, Borland's short lived Delphi for Linux?
Unimportant tangent, but I think FireMonkey is a terrible name for a UI framework. I don't know why, but I hate it.
The C# world also has quite a few paid libraries, especially for UI stuff.
Quite a few years ago I worked at a company using Delphi, and judging by their homepage they are still using it. A company making industrial machinery, with a tiny internal software department for the software for provisioning and maintaining the machines, as well as the control room software. Usability and development velocity is more important than looking hip, and easy access to hardware interfaces is paramount. And compared to developer salaries those license costs really aren't that bad
On Microsoft, Apple, and game consoles, it is still pretty common to pay for development tools.
Also pretty common in enterprise tooling, which is the market of tools like Delphi.
The alternative is everyone getting surprised that their favourite free software development tools (only free thanks to VC money), eventually goes away.
(Technically it is optional if you don't need to ship signed apps or submit to the app store and you don't care about the rest of Apple's developer program.)
They have free community edition. Main restriction seems to be: "If you're an individual, you may use Delphi CE to create apps for your own use and apps that you can sell until your revenue reaches US$5,000 per year."
I have not tried the IDE, but I like FreePascal. The compiler is fast and it has great multiplatform and cross-compilation support. In particular for older platforms.
It feels more stable and mature than most other languages. I do not know if there are enough developers keeping it alive, but hopefully it will mostly get bug fixes and ports to new platforms. Better if they do not mess with the language or standard libraries. Those that want a programming language that keeps breaking backwards compatibility every few months have plenty to choose from already.
Lazarus is a pretty sweet solution on Linux (or Codetyphoon, if you want more out of the box components).
