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.

pHash
Glad it's on Github here: https://github.com/aetilius/pHash
Github tends to outlive the homepage of some projects. I got worried when I read this:

Use fast data algorithms (2021)
I'm late on the reply but I was using xxhash for something similar, but found that Meow hash was faster for me. Feel free to benchmark, since I'm sure it could vary depending on CPU architecture.

Cryptanalysis of Meow Hash
for everyone who doesn't think highly of Casey Muratori (or at least the way he conducts himself online), the author of Meow Hash, took the criticism quite graciously:

Reading a file in parallel
Is a standardized hashing algorithm required? SHA256 takes several CPU cycle per byte, but there are several hashing algorithm utilizing AES-NI that gives them 15-16 bytes per cycles, which translates to tens of gigabytes per second on modern CPU. At least one of them has been ported to .NET Core, and from what I see properly calls AES primitives.

76% Faster CPython
MeowHash is the fastest non-cryptographic hash available online, and if it were used in CPython, which performs a hash for every fundamental operation in the language, then Python would be much faster.

New Bare Hash Map: 2X-3X Speedup over SOTA
Meow hash claims 3-4x faster hashing over this, still passes smhasher, and is a few years old. https://mollyrocket.com/meowhash

A Hashmap for the C Programming Language
Have you seen the meow hash implementation? Would that be suitable for this ?
What are some alternatives?
