A fast compression/decompression library optimized for speed over maximum compression.
Snappy is a fast compression/decompression library developed by Google, optimized for high-speed data processing with reasonable compression ratios. It solves the need for rapid data compression and decompression in performance-critical applications, such as real-time systems and large-scale storage. Unlike libraries aiming for maximum compression, Snappy prioritizes speed, making it significantly faster than alternatives like zlib in its fastest mode.
Developers and engineers working on performance-sensitive applications, such as real-time data processing, large-scale storage systems, or any scenario where compression speed is more critical than maximum compression ratios.
Developers choose Snappy for its exceptional speed, stability, and robustness, especially in production environments like Google's, where it has processed petabytes of data. Its optimized performance for 64-bit x86 processors and focus on practical compression make it a reliable choice over slower, more complex alternatives.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Achieves compression at 250 MB/sec and decompression at 500 MB/sec or more on modern hardware, significantly outpacing zlib's fastest mode as highlighted in benchmarks.
The compression format is stable across versions, ensuring long-term compatibility and reliability, proven by processing petabytes in Google's production environment.
Designed to handle corrupted or malicious input without crashing, enhancing security and reliability in real-world deployments.
Primarily optimized for 64-bit x86 processors, delivering top performance on standard server and desktop hardware, with support for ARM via best-effort tuning.
Produces compressed files 20% to 100% larger than zlib's fastest mode, making it inefficient for storage-sensitive applications where space is a premium.
Assumes little-endian and 64-bit x86; on big-endian or non-x86 architectures like ARM, performance may degrade due to emulated operations and lack of native optimizations.
Core library is in C++, with other language bindings being third-party, which can add complexity and dependency issues for projects not using C++.
