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.

Libsodium: A modern, portable, easy to use crypto library
For C/C++ projects that use meson as the build system, there is an excellent way to manage dependencies:
https://mesonbuild.com/Wrapdb-projects.html
https://mesonbuild.com/Wrap-dependency-system-manual.html
meson will download and build the libraries automatically and give you a variable which you pass as a regular dependency into the built target:
https://github.com/qemu/qemu/tree/005ad32358f12fe9313a4a0191...
https://github.com/harfbuzz/harfbuzz/tree/main/subprojects
https://github.com/harfbuzz/harfbuzz/blob/37457412b3212463c5...
Or, if you're using proper operating systems, they're managed by the usual package manager, just like everything else.

Text Rendering Hates You
If you sympathize with the travails of people working on text rendering in applications, please consider supporting (among other projects):
1. The LibreOffice project (libreoffice.org), the free office application suite. This is where the rubber hits the road and developers deal with the extreme complexities of everything regarding text - shaping, styling, multi-object interaction, multi-language, you name it. And - they/we absolutely need donations to manage a project with > 200 million users: https://www.libreoffice.org/donate
2. harfbuzz (https://harfbuzz.github.io), and specifically Behdad Esfahood the main contributor. Although, TBH, I've not quite figured out whether you can donate to that or to him. At least star the project on GitHub I guess.

ImGui or text rendering libraries
As for text, it depends very heavily on what exactly you need. Simple ASCII text and bitmap fonts? Just do it yourself or get a .bdf parser. Simple Latin/Cyrillic-like writing with ok-looking vector fonts (ttfs)? stb_truetype has all you need. Font hinting, subpixel rendering? You use freetype. More complex writing like Arabic? You will have to do shaping as well, say with HarfBuzz. Need right-to-left or unidirectional text? Hypenation? Go for platform APIs if you can (DirectWrite om Windows, CoreText on Mac).

QuestPDF: Modern .NET library for PDF document generation
Gold standard? Even though serious bugs are not fixed [1] because "the code is too fragile to touch at this point"? Looks like Android uses HarfBuzz, if so it can't be that bad.

A Programmable Markup Language for Typesetting [pdf]
The linked libraries are not even close to solving limited subsets of problems solved by FreeType or HarfBuzz. No test is needed if they do not even have a working implementation of particular requisites: Do they work on heterogeneous layouts, directions, languages, locales, scripts, symbols and composites, extensions, variations, legacy, missing, partial or corrupted instructions, standards interpretations, platforms, output devices, nonstandard point structures and grids?
They do not. What they solve is almost a toy problem compared to the size, scope and breadth of these libraries.
Just because some project is implemented in Rust does not make it comparable never mind superior by default.
There is a world out there and it is not homogeneous format and standards-compliant Latin fonts in English LTR text in linear disposition with some generic rectangular subpixel rendering on a regular rectangular grid.
I warmly welcome you to browse closed issues of FreeType [1] and also the closed issues of HarfBuzz [2]. If you feel inspired please do also look into mailing lists and discussion pages related to the development, building, tracking and patching of packages of these projects in any of the numerous places it is used.
The only argument Rust people have is in relation WASM but if you insist in targeting WASM why not fork FreeType, strip it to the strict subset of features your application needs and target it?
Why do it in the first place? Why reinvent the wheel?
As such I will restate my view: I see no gain in using any of these subpar libraries.

AWS Libcrypto for Rust
Again, this is just a temporary situation, and a matter of burning down a list of small tasks. Not that the OpenSSL license issue is a big deal for most anyway. Feel free to help; see this issue filed by Josh Triplett: https://github.com/briansmith/ring/issues/1318#issuecomment-...

A brief guide to choosing TLS crates
Note also that rustls depends on ring, which has architecture-dependent code in it that is not as widely compatible as eg. OpenSSL/GnuTLS/Mbed-TLS. For example, MIPS is not supported by ring.

Releasing Rust Binaries with GitHub Actions - Part 2
The AWS Rust library we were using as a dependency depended on a cryptography library called ring. This library leverages C and assembly code to implement its cryptographic primitives. Unfortunately, cross compiling when C is involved can add complexity to the build process. While it might've been possible to overcome these issues I decided that it wasn't worth digging into more.

Urgent Upcoming OpenSSL release patches critical vulnerability
That'd be great. Thanks Brian. Re: making ring portable to all platforms: IBM have been graciously maintaining a up to date patchset for Ring for years now and there's an outstanding PR here you may not have seen since they filed it in 2020... https://github.com/briansmith/ring/pull/1057

OpenSSL Security Advisory [5 July 2022]
Beyond the simple matter of Rust being much newer than OpenSSL, one concern for some cryptographic primitives is the timing side-channel.
https://en.wikipedia.org/wiki/Timing_attack
In high level languages like Rust, the compiler does not prioritise trying to emit machine code which executes in constant time for all inputs. OpenSSL has implementations for some primitives which are known to be constant time, which can be important.
One option if you're working with Rust anyway would be use something like Ring:
https://github.com/briansmith/ring
Ring's primitives are just taken from BoringSSL which is Google's fork of OpenSSL, they're a mix of C and assembly language, it's possible (though fraught) to write some constant time algorithms in C if you know which compiler will be used, and of course it's possible (if you read the performance manuals carefully) to write constant time assembly in many cases.
In the C / assembly language code of course you do not have any safety benefits.
It can certainly make sense to do this very tricky primitive stuff in dangerous C or assembly, but then write all the higher level stuff in Rust, and that's the sort of thing Ring is intended for. BoringSSL for example includes code to do X.509 parsing and signature validation in C, but those things aren't sensitive, a timing attack on my X.509 parsing tells you nothing of value, and it's complicated to do correctly so Rust could make sense.
