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.

How to fuzz java code with jazzar?
Ex Radmasa
- Radamsa – test case generator for robustness testing

Anyone knows open source mutator support regex?
I used to use radamsa to make my own fuzzer, but it does not support regex to generate datas.

What Is Fuzz Testing?
At simplest and most straight forward level fuzz testing is pretty simple to get started with. Collect some input(API calls, files, etc.), pass it to fuzzer(for example radamsa[0]), throw it at program and observe...
Ofc, depending on system collecting input and sending it to system might be bit more complicated. Hardest part is often the observing and finding that an error happens.
Not that this gets you full coverage, for more complex things like protocols something custom that takes lot more effort is probably needed.

Prefer table driven tests (2019)
There's some efforts to guide test generation for property based testing to make the instruction pointer explore as large a space as possible.
This effort is more mature in the fuzzing community. See eg American Fuzzy Lop https://github.com/google/AFL

C++ Faker library
What you're describing, just generating random input to test a program, is sometimes called "blind fuzzing" but the state-of-the-art is far beyond that. Maybe try reading through the documentation of e.g. https://github.com/google/AFL to see what a fuzzer does and why just producing random input isn't even scratching the surface.

Hyperpom: An Apple Silicon Fuzzer for 64-bit ARM Binaries
for general riscv I used to use this https://github.com/google/AFL I dont know if it supports x64 tho.

One year ago I wrote a buddy memory allocator - project update
I wrote this little fuzz test target in order to fuzz it with afl (under ASan and UBSan):

Beariish/little: A small, easily embedded language implemented in a single .c file
afl, which is trivial to apply to this program:
-
TCL like interpreter suitable for embedded use
I made my own version of a TCL interpreter (well, a very TCL like langauge) derived from "picol" available at https://github.com/howerj/pickle. There are many different re-implementations and derivatives of this interpreter but they all seem very "crashy", this one has been significantly hardened by using a fuzzer on it which ran for months called American Fuzzy Lop https://lcamtuf.coredump.cx/afl/ . It is also more suitable for embedded use whilst still not having arbitrary restrictions like many other implementations.

What's in your tool belt?
On Linux afl is a very powerful bug-finding tool, and it's a great companion when doing code review. Composes well with ASan and UBSan.

What are some alternatives?
onefuzz - A self-hosted Fuzzing-As-A-Service platform
boofuzz - A fork and successor of the Sulley Fuzzing Framework
beacon-fuzz - Differential Fuzzer for Ethereum 2.0
honggfuzz - Security oriented software fuzzer. Supports evolutionary, feedback-driven fuzzing based on code coverage (SW and HW based)
winafl - A fork of AFL for fuzzing Windows binaries
Cppcheck - static analysis of C/C++ code
doubleback - Doubleback provides round-trip parsing and printing of 64-bit double-precision floating-point numbers using the Ryu algorithm implemented in multiple programming languages. Doubleback is biased towards "human-friendly" output which round-trips consistently between binary and decimal.
HTTP Parser - http request/response parser for c
cryptofuzz - Fuzzing cryptographic libraries. Magic bug printer go brrrr.
PHP CPP - Library to build PHP extensions with C++
