This is a simple tool written in python, that allows you to generate fractals and save them in high resolution.
You can download this repo and then install required libraries by running this command in the project directory:
pip3 install -r requirements.txt
After launching main.pyw file you should see this interface:

Escape boundary- determines how far should point go from the origin to be considered as escaped.Max iteration- maximum number of iteration function calls, after which point is considered as not escaped.Iteration function- consists ofc(constant value) andz(iterable value).Complex value- constant value, selected by clicking on complex plane.
After changing parameteres, press Render button to see the results. To save fractal press Save button. You can change the resolution of saved fractals (and other parameters, like window size) in config.cfg file.
Example of generated 10000x10000 image of fractal:
