The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Real-world examples of std::expected in codebases?
Example of other people trying to do it in a generic way, as a separate library (instead of in the utility part of some bigger codebase): - https://github.com/bitwizeshift/result - https://github.com/oktal/result - https://github.com/basicpp17/result17 - https://github.com/p-ranav/result

std::expected (with monadic interface) implementation in C++20 (P0323, P2505)
As someone who is new to this API (so I can't discern from the list of features which might be better for my use case), I second the question, and I'd like to extend the question to how it compares to https://github.com/martinmoene/expected-lite and https://github.com/bitwizeshift/result as well.
- A modern Result type in C++
- C++ “result” type based on modern languages like Swift and Rust
- Modern C++ "result" type based on Swift / Rust
What are some alternatives?
When comparing expected and result you can also consider the following projects:
expected-lite - expected lite - Expected objects in C++11 and later in a single-file header-only library
result17 - A rust like Result type for modern C++
libaegis - OpenCV pipelines with lambda functions
BackportCpp - Library of backported modern C++ types to work with C++11
Simple-Iterator - Simple to use iterator_interface for several iterator categories
RSL - ROS Support Library
