## What it is
Abseil is an open-source collection of C++17-compliant libraries drawn from Google's internal codebase, designed to augment the C++ standard library. It provides production-tested utilities for strings, containers, synchronization, time, hashing, numerics, debugging, and more, built with Bazel or CMake.

## Use cases
- use Google's production-tested C++ utility libraries in my project
- get std::string_view-like types and utilities on older C++ standards
- find better mutex and synchronization primitives than std::mutex
- parse and format times with timezone support in C++
- add 128-bit integers and bitwise math to C++ code
- get stack traces and leak checking for debugging C++ programs
- share common code between gRPC, protobuf, and TensorFlow projects

## When to choose
- starting a new C++ project that wants well-tested foundational utilities
- your project depends on Google OSS like gRPC, protobuf, or TensorFlow that already use Abseil types
- you need utilities missing from or diverging from the C++ standard with clear rationale
- you can adopt a live-at-head or LTS release workflow

## When to avoid
- you want a minimal dependency footprint and only need one or two small utilities
- your toolchain cannot target C++17
- you need a framework or application rather than a utility library
- you cannot tolerate occasional API changes across LTS releases

## Facets
- artifact type: library
- maturity: stable
- function: developer-tools, concurrency, error-handling, date-time, logging, serialization, math, cryptography
- domain: developer-tools, cross-platform, performance
- platform: windows, cpp, cross-platform
- tags: cpp17, google, standard-library-augmentation, bazel, cmake, containers, strings, synchronization, time, hashing, algorithms, linux, macos
