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.

buddy memory allocator - project update (2 years)
If you need a sub-allocator with predictable performance feel free to give it a try. The code is here and it is licensed under the 0BSD license, making it as lax and as close to public domain as possible. Comments, issues and PRs are always welcomed and appreciated. Thanks!

Open-source MISRA-compliant projects
I maintain a project that's not technically MISRA compliant (due to being a memory allocator and MISRA disallowing the very idea) and I keep it at 100% test coverage with support for multiple compilers and operating systems. Over time I had a few users reporting back - since it's working for them I count that as success. Is it wildly popular ? Of course not, but it doesn't have to be.

One year ago I wrote a buddy memory allocator - project update
You are right about the tests - they are written with 64-bit in mind. I ought to rework them to switch sizes based on arch but that will take a weekend. I've filed https://github.com/spaskalev/buddy_alloc/issues/19 to track this.

is there some good tutorial about how malloc or mcheck works?
I also maintain a application-based malloc (that doesn't do obtaining and releasing memory through the OS, just managing sub-diving a larger memory block into smaller requests) at https://github.com/spaskalev/buddy_alloc - feel free to ping me with any questions about it.

I'm giving out microgrants to open source projects for the third year in a row! Brag about your projects here so I can see them, big or small!
I'm the author of https://github.com/spaskalev/buddy_alloc - a custom memory allocator for C (modern C11, works with C++ as well) designed for predictable and repeatable performance. It is suitable for use in embedded, games and any other system with soft or hard real-time demands. It has 100% line and branch test coverage and uses a fixed amount of space on the call stack when called. Recently the project had its first external contribution as well. Cheers!

What is your own favorite C project?
I made a memory allocator that turned out rather neat - https://github.com/spaskalev/buddy_alloc

Immediate Mode GUI Programming
There is also microui, which I like[0].
Which I forked to work with SDL2[1], no guarantees. It's fun to hack on.

What should I use to make GUI with SDL
Otherwise, https://github.com/rxi/microui is small enough that you can hack around. Look at the issue though, there's a bit of unaligned access there.

ImGui or text rendering libraries
For GUI, there are lots, most well-known of course being Dear Imgui, for which people have made auto-generated C bindings. Another mature but a lot simpler option is Nuklear, as others have mentioned. Even more minimalistic (it's just 1KLOC) is microui. There are a lot more, just google "imgui library c".
- A lightweight, simple, fast, feature-filled, text editor written in C, and Lua

Nuklear – A single-header ANSI C immediate mode cross-platform GUI library
The price for the 'lightest' UI toolkit probably goes to microui:
https://github.com/rxi/microui
Just around 1100 lines of C code.
You need to bring your own renderer, but that's the same for Nuklear or Dear ImGui.
I wrote a WASM wrapper for the microui demo too:

I made a shortlist of good libraries for my GUI C project and I want your thoughts and comments.
Good C library list: https://en.cppreference.com/w/c/links/libs https://github.com/Immediate-Mode-UI/Nuklear + C89, no dependencies, public license. 5/5 https://www.tecgraf.puc-rio.br/iup/ + good tutorial and wiki guides 5/5 https://libsdl.org/ + infinite possibilities - whole library for making games, forums, wiki - complicated, not many C tutorials, need to manage game states... 4/5 https://github.com/lvgl/lvgl + good docs - for embedded systems 4/5 https://github.com/ocornut/imgui + Popular, inspired Nuklear - for C++ 3/5 https://docs.enlightenment.org/api/imlib2/html/ + very efficient, used in Conky - uses X so only for Linux, just for displaying images and text and stuff 2/5 https://github.com/rxi/microui + simple, small - you need to handle your own drawing 2/5 GTK+ - no

I haven't been using Linux that much yet, but because of my experience with Xfce, and because others don't seem to enjoy desktop environments on Linux too much, I want to create my own.
Really? Here's a minimal UI with I believe less LOC than Suckless DWM. It's not a full DE, but I imagine you could probably turn it into one without adding that much more code.
