April 2025 TIOBE Index: Kotlin, Ruby & Swift Drop in Recognition


Recognition consolidated within the high 20 programming languages in April, in keeping with TIOBE Software program CEO Paul Jansen. C overtook Java for the quantity three spot between March and April.

Key takeaways from the April TIOBE Index rankings:

  • SQL continues to fall because it has accomplished over the previous couple of months, dropping to the quantity 10 place.
  • C++ held on to the quantity two spot, exhibiting a major year-over-year enhance within the proprietary factors system.
  • Python’s recognition dipped barely month-over-month, nevertheless it nonetheless holds a major lead over the second-place language, C++.

Kotlin and Swift decline after they’re not the most effective picks for cellular

Kotlin, Ruby, and Swift are all “prone to exit of trend” after reliably holding on to spots within the high 20, Jansen stated. Why? For Kotlin and Swift, the reply comes right down to new programming languages coming into and competing inside their niches.

“Kotlin and Swift have the identical cause why they’re declining,” Jansen stated. “They’re each primarily used for one specific cellular platform, Android and iOS, respectively, whereas there are different sufficiently good languages and frameworks to develop cross platform these days.”

Swift can technically be used for Android improvement as nicely, however it could current pointless boundaries within the course of.

In the meantime, Ruby is a general-purpose language as soon as thought of a rival to Python; it competed for area with Perl, too. Now, Python has pulled nicely forward of each Python and Perl (which sits at nineteenth on the TIOBE Programming Neighborhood Index), and Ruby garners much less curiosity.

Curiosity consolidates in the most well-liked programming languages

Now might not be the time to attempt to create a brand new programming language or to study one of many lesser-known choices. Together with rating particular person programming languages, Jansen additionally retains an eye fixed on your complete market. In April, he famous the highest 20 languages account for 82.56% of the overall market, in comparison with a ordinary share of about 75%. The business is in what he referred to as “a consolidation part.”

“Which means the market is a bit defensive, preferring confirmed expertise to making an attempt out new applied sciences,” Jansen stated.
