Dart Breaks Into TIOBE Top 20 as Rust Falls Out of Top 10 (Nov 2026)

TIOBE November 2026 Programming Language Rankings Released

The TIOBE Programming Community Index for November 2026 has been published. This month's headline: Dart surprisingly breaks into the top 20 for the first time in the index's history.

Dart Enters Top 20 for First Time

Dart has historically entered the TIOBE top 20 for the first time. Last month Julia had just re-entered the top 20, but this month Dart replaced it. The trend was already visible in October when both OCaml and Dart were identified as candidates for the top 20.

Flutter Ecosystem Drives Dart Adoption

Dart's rise is inseparable from Flutter, Google's cross-platform mobile application development framework, which is the primary force behind Dart's popularization. Flutter has become one of the leading technologies in cross-platform mobile development. The Dart language itself does not have particularly unique features despite incorporating many modern programming language characteristics. Dart's success is largely due to the powerful Flutter ecosystem and the convenience of building multi-platform applications from a single codebase.

Dart is the programming language; Flutter is the cross-platform framework for building application UIs using Dart. Their combination's greatest value is that developers can reuse the same codebase to build Android, iOS, Windows, macOS, Linux, and Web applications.

Four Reasons for Dart and Flutter's Popularity

Broad application coverage: Enterprises do not need to develop two completely separate applications for Android and iOS.

Hot reload boosts efficiency: After modifying Dart code, developers can quickly see UI changes without a full rebuild each time.

Strong UI consistency: Flutter renders UI through its own rendering system, reducing differences in component behavior across platforms.

Ecosystem drives language adoption: Developing Flutter applications typically requires Dart, so growth in Flutter developers also drives Dart learning and usage.

The TIOBE November 2026 report emphasizes this core point: Dart's entry into the top 20 is mainly driven by the Flutter cross-platform application ecosystem, not by the language's own uniqueness.

Other Notable Ranking Changes

R ranks #7, entering the top 10.

SQL ranks #8, also entering the top 10.

PHP rises to #12; the veteran language persists.

Assembly language re-enters the top 20.

Perl falls from #9 a year ago to #15.

Visual Basic drops to #9.

Discrepancy Between Rankings and Developer Perception

An interesting phenomenon: TypeScript ranks only #41, Kotlin #33, Ruby #30. Developers who frequently work on web projects may question the ranking's authenticity. TIOBE measures comprehensive attention to programming languages, not actual code usage volume, nor which language is more advanced.

Therefore, rankings are just a reference; real technology stack choices should depend on the specific project.

Vibe Coding and AI Agent Development Trends

Currently, Vibe Coding for websites favors TypeScript + Next.js; for AI Agents, Python is preferred; for cross-platform apps, Dart + Flutter is an option; for high-performance Agent CLIs, Rust, Go, and TypeScript are common.

The most common Vibe Coding combinations are TypeScript + Next.js and Python + FastAPI. Open-source AI programming Agent implementations primarily use TypeScript, Python, and Rust.

Top 10 Languages and Python's Year-over-Year Decline

This month's top 10 are: Python, C, C++, Java, C#, JavaScript, R, SQL, Visual Basic, Go.

Python remains #1 with a 20.86% rating, but its index dropped 2.51 percentage points compared to the same period last year.

Learning Recommendations by Domain

AI / Data Science: Choose Python — now, in the future, and for a long time to come.

Web Frontend: Learn JavaScript first, then TypeScript — no second choice.

Backend / Enterprise Development: Java or C# — old but not dead, stable job market.

Systems Development, Game Engines, Low-level: C++ remains the mainstay; Rust is a worthwhile long-term investment.

High Difficulty Challenge: Rust or Go — fewer jobs but even fewer candidates, clear salary premium; suitable after gaining some foundation, not as a first language.

Regardless of which language, mastering one deeply is far more useful than superficially sampling many.
