C++ Community Chooses Best Libraries of the Year: Voting Results

C++ Community Chooses Best Libraries of the Year: Annual Voting Results

The annual voting among C++ developers has concluded with the announcement of the best libraries that had the greatest impact on the language ecosystem in 2024. This year, competition was incredibly high, but the community made its choice. We present the winners in key categories.

Winners in Main Categories

The voting took place in three categories: "Library of the Year," "Best Data Tool," and "Breakthrough of the Year." Here is how the votes were distributed.

Library of the Year: Boost.URL

The Boost.URL library received the highest number of votes. It provides a modern and safe API for working with URLs: parsing, encoding, assembly, and comparison. Developers note that Boost.URL significantly simplifies HTTP request handling and integration with web services. Key advantages:

• Full support for RFC 3986 (URI standard).
• High performance due to zero-copy operations.
• Compatibility with C++17 and newer.

Best Data Tool: fmtlib

The fmtlib library, known for its fast string formatting, was recognized as indispensable for data processing. It underlies std::format in C++20, but the community values it for its extended capabilities:

• Support for custom types via operator<< overloading.
• Localized formatting of numbers and dates.
• Minimal overhead compared to iostream.

Breakthrough of the Year: Simdjson

The Simdjson library for ultra-fast JSON processing was a true revelation. Using CPU SIMD instructions, it parses JSON at speeds up to 10 GB/s. This opens new horizons for high-load systems:

• Speed 10-20 times higher than standard RapidJSON.
• Support for streaming processing of large files.
• Zero-copy data parsing.

Why These Libraries Matter for C++?

The community's choice reflects key trends of 2024: security, performance, and convenience. Boost.URL reduces vulnerability risks, fmtlib makes code more readable, and Simdjson proves that C++ remains the language for the highest speed requirements. All three libraries are actively maintained and have stable releases.

For those just starting to learn C++, these libraries will be an excellent start for understanding modern practices. And experienced developers can use them as a benchmark for code quality.

What's Next?

The voting organizers have already announced that next year they will add categories for asynchronous programming and machine learning. Follow the news on the community website – perhaps your library will become the winner in 2025.
