Highlights & Movers (vs August 2025)
| Change | Detail |
|---|---|
| Rust enters top 10 | 1.45% (+0.31%), up from #18 a year ago; memory safety + performance drive adoption in systems programming and AI infrastructure |
| MATLAB out of top 20 | First time in over a decade; now #25 at 0.71%. TIOBE's CEO cites a paid-license model in a world of free languages, plus slow language evolution |
| Biggest risers | Ruby +10 places (0.98%), Rust +8, Swift +8 (0.96%), SQL +4 (1.88%), R +5 (1.56%) |
| Biggest fallers | Perl -9 places (0.94%), Go -6 (1.07%), Fortran -4, Delphi/Object Pascal -1 |
| Python's YoY dip | Still #1 at 18.53% but -7.61pp YoY — the largest drop in the top 10 (base-effect dilution as other languages gain share) |
| Watchlist | OCaml (#29, 0.63%) and Zig (#41, 0.43%) keep growing; TIOBE expects they may enter the top 20 |

FAQ
What is the most popular programming language in August 2026?
Per the TIOBE Index (Aug 2026), Python is #1 at 18.53%, followed by C (11.10%), C++ (8.62%), Java (8.25%) and C# (4.09%). PYPL also ranks Python first at 47.49% — both indices agree on the leader.
Why did Rust enter the TIOBE top 10 for the first time?
Rust reached #10 in August 2026 at 1.45% (+0.31%), up from #18 a year earlier. Memory safety fits systems programming and AI infrastructure, with large projects (Linux kernel, browser engines) adopting it and an active community.
Why did MATLAB fall out of the TIOBE top 20?
MATLAB is out of the top 20 for the first time in over a decade (now #25, 0.71%). TIOBE's CEO cites two reasons: a paid-license model is a growing disadvantage in a world of free languages (only Delphi/Object Pascal also requires a paid license in the top 20), and MATLAB evolves slowly while Python, Rust and newer languages keep adding modern features.
What's the difference between TIOBE and PYPL?
TIOBE combines search-engine results, courses and third-party vendors (updated monthly, with YoY changes). PYPL counts only Google tutorial searches (Python 47.49% as of Jul 2026). Both measure popularity, not "best" language or lines of code; PYPL swings more and should be cited with its caveat.
What language should I learn in 2026?
It depends on the domain: Python for AI/data, Rust for systems, Go or Java for backend, TypeScript for frontend, Swift/Kotlin for mobile. Python remains the usual first language for beginners, but TIOBE shows its share fell 7.61pp YoY — pairing it with a backend or systems language is a common strategy.
