Discover the latest TIOBE Index rankings for April 2025. See which programming languages are rising, which are falling, and what this means for developers and businesses.

The TIOBE Index for April 2025 has been released, showcasing the most popular programming languages based on global usage and industry demand. Python continues to dominate, securing the top spot with a 23.08% rating, followed by C++ and C.

Notably, Kotlin, Ruby, and Swift have seen a decline in popularity, signaling a shift in mobile development trends. Meanwhile, the top 20 languages now account for 83.56% of the total market, reflecting a consolidation phase where developers prefer established technologies over emerging ones.

April titles: #Kotlin, #Ruby, and #Swift, once among the top 20 programming languages, are struggling.
#Kotlin, #Ruby, and #Swift held steady positions in the top 20 of the TIOBE index until recently.
But now they appear to have lost momentum and are likely to disappear. The decline of #Kotlin and #Swift is due to the same reason. Both are primarily used for a single mobile platform, #Android and #iOS, respectively, while other languages ​​and frameworks are good enough for developing cross-platform apps at the moment. While #Swift can be used for Android development, it's extremely difficult. #Kotlin on iOS hasn't seen much success. #Ruby, however, is a different story. For many years, #Ruby competed with #Python and #Perl. While Perl was on the decline, #Ruby stabilized. But now that #Python has become the lingua franca of the programming world, there's not much room left for #Ruby. Another interesting observation is that the world of programming languages ​​is going through a consolidation phase. The top 20 languages ​​currently cover 83.56% of the total market. This is a very high figure, as it typically stands at around 75%. This suggests that the market is somewhat conservative, preferring proven technologies over experimenting with new ones.

For businesses and developers, staying updated with these rankings is crucial for making informed decisions about programming language adoption. Whether you're starting a new project or refining your skill set, the TIOBE Index offers valuable insights into industry trends.
