GoKawiilTIOBE Index: R Passes SQL, Julia Re-Enters Top 20, Go Drops Out of Top 10
TIOBE's October 2026 language popularity rankings show R overtaking SQL in the top 10, while Julia returns to the top 20 for the first time in three years, climbing from No. 21 to No. 18. Go fell out of the top 10, dropping from No. 8 a year ago to No. 11, and Delphi/Object Pascal tumbled from No. 9 to No. 19. Python, C, C++, Java, C#, and JavaScript retain their top-six spots, Rust holds at No. 10, and Dart and OCaml both surged toward the top 20.
GoKawiil's interpretation of the reporting above, not reported fact.
TIOBE CEO Paul Jansen attributes Julia's rise to demand for languages that pair high performance with easier learning for numerical computing, suggesting developers may be seeking alternatives to Python's speed limits and C++'s complexity. The addition of Mandarin search terms to TIOBE's methodology could also reshape rankings by capturing a broader, more global pool of programming activity. Go's and Delphi's declines may reflect shifting developer interest rather than any single event, though the index itself doesn't explain causes.
- R overtook SQL and Julia re-entered the top 20 after a three-year absence.
- Go dropped out of the top 10, falling from No. 8 to No. 11 year-over-year.
- TIOBE now includes Mandarin Chinese search terms, aiming for broader geographic representation.
