About:
Rapidfuzz-cpp is a high-performance C++ header-only library for rapid fuzzy string matching. It implements the Levenshtein Distance and related algorithms to efficiently calculate string similarity ratios. Its primary value proposition is delivering speed comparable to the established RapidFuzz Python library while remaining lightweight and dependency-free.

Key Features:

Header-only library (no build required)
High performance with SIMD optimizations
Provides Levenshtein distance and similarity ratios
C++11/14/17 compatible

Use Cases:

Implementing spell-checkers and auto-correct features
Data deduplication and record linkage
Natural Language Processing (NLP) preprocessing
Command-line interface (CLI) argument matching

Alternatives:

TheFuzz – Python-based implementation; rapidfuzz-cpp offers significantly faster performance for C++ applications.
std::string::find – Standard library search is exact; rapidfuzz-cpp handles typos and partial matches.
