Main Differences Between Abseil and Boost

Aspect	Abseil	Boost
Purpose	Modern C++ utilities for performance, simplicity, and Google-style coding.	Broad, comprehensive set of libraries for general-purpose C++ development.
Design Philosophy	Focuses on modern C++ (C++11/14/17), clean APIs, and production-grade code.	Older, supports pre-C++11, with some legacy and verbose APIs.
Size & Scope	Leaner, focused on core utilities (e.g., containers, strings, time).	Massive, with over 160 libraries (e.g., networking, math, filesystem).
