Fractalysis is a free Mandelbrot viewer that runs in your browser. It zooms far deeper than double precision allows, using perturbation and arbitrary-precision arithmetic.

I originally started this project 10 years ago, frustrated with existing limited or difficult to use viewers. I just finished porting this to web for everyone to enjoy directly :)

There are still features I would like to add, like creating animations, automatic zooming and advanced user settings.

Feedback is always appreciated!
