Mandel Machine is "a highly efficient Mandelbrot set explorer developed by Botond K?sa". It can be downloaded here:
http://web.t-online.hu/kbotond/mandelmachine/

The most important features I think are:
1. use of assembly language and modern instruction sets for the best speed possible
2. perturbation and series approximation with automatic glitch detection and repair
3. up to 32 threads
4. up to 2^10000 magnification
5. graphical interface similar to Ultra Fractal

There is a lot more information in the previous fractalforums subforum:

I like Mandel Machine. The interface is very intuitive and it is very easy to use. And it doesn't crash on my computer =P Also I converted the parameters of fractals created with Kalle's Fraktaler to Mandel Machine format to post-process the fractal.
A question, Mandel Machine and Kalle's Fraktaler use the perturbation algorithm to get very deep fractals. Are there other free fractal software that use perturbation?

Thanks, Adam.
But I was looking for something more user-friendly. And I have never compiled from git.
