Most Popular Programming Languages

About This Dataset

This chart shows the most popular programming languages by their rating in the TIOBE Index for July 2026, which measures language popularity based on search engine results for skilled engineers, courses and third-party vendors.

✨ AI Insight

Python leads the TIOBE Index at 18.94 percent, nearly double the score of second-place C at 10.86 percent, reflecting its dominance in data science, AI and education. The classic systems languages C and C++ remain firmly in the top three, together with Java, showing the enduring role of established languages in performance-critical and enterprise software. C# and JavaScript follow in a middle tier, while the appearance of SQL, R and, notably, Rust in the top ten highlights the rising importance of data querying, statistics and memory-safe systems programming. Rust's entry into the top ten for the first time is a milestone, signalling growing industry adoption of a language designed to combine safety with speed. The steep drop from Python to the rest illustrates how concentrated developer attention has become around a single leading language.
