Survey: Popular C++ Frameworks in Production in 2024

Survey: Which C++ Frameworks Dominate in Production in 2024

The C++ community continues to surprise. Despite the language's age (almost 40 years), it remains one of the most in-demand in high-load systems, games, finance, and embedded development. But which tools and libraries are teams actually using in production projects? We analyzed data from several public surveys (including the JetBrains Developer Survey and C++ Foundation Survey) for 2023–2024 and identified key trends.

Top Frameworks: Who's in the Lead?

The survey showed a clear division into three categories: "heavy artillery" for GUI and infrastructure, lightweight utilities, and niche solutions.

• Qt — the undisputed leader (about 38% of respondents). Used in production for cross-platform GUI applications, embedded systems, and even in the automotive industry (e.g., in instrument panels).
• Boost — 34%. Not so much a framework as a "standard library before the standard." Smart pointers, asio, filesystem — these modules are in every second production codebase.
• POCO — about 12%. Actively used in server-side development (REST API, network services) and IoT.
• OpenCV — 9%. Machine vision, image and video processing — no computer vision project can do without it.
• Folly (from Facebook/Meta) — 5%. Growing in popularity in high-load backends and social networks.

Unexpected Favorites

This year, Abseil (Google) and nlohmann/json appeared in surveys for the first time. The former as a replacement for Boost in companies transitioning to C++17/20, the latter as the de facto standard for working with JSON. Interestingly, 7% of respondents stated that they do not use third-party frameworks at all — only the STL and custom utilities.

Why is Framework Choice Critical?

Developers highlight three main criteria when choosing:

• Performance — especially in real-time systems (games, finance).
• ABI stability — to avoid rebuilding the entire project when updating.
• Community and documentation — Qt and Boost are unmatched here.

Trends: Where is C++ Heading?

Surveys confirm a gradual shift away from monolithic frameworks towards modular libraries. More and more teams use Conan or vcpkg for dependency management instead of including an entire framework. There is also a noticeable increase in interest in C++20 — modules, coroutines, and ranges reduce the need for Boost.

Conclusion: if you are starting a new production project in C++, look towards Qt (if you need a GUI), POCO (for network services), or Abseil (if the team is young and likes the modern standard). And Boost remains the universal soldier — it is known, loved, and continues to be used, even if the project is formally C++20.
