I'm looking for a Windows program/solution to broadcast actions (mouse movement & clicks, keyboard would be a plus) in real time to multiple browser windows. Best way to describe the functionality I'm after is something like Bluestacks with its sync feature, but in my case with regular desktop browsers instead of emulated android devices. The goal would be to have 20-50 "slave" browsers that receive inputs from a single "master" browser.
I have tried for a long time to find a program that does this, but so far I've not been able to find one. If such thing doesn't exist, I would also be interested to know if this sort of program would be possible/complicated/expensive to code from scratch, as I have no coding experience myself (except basic level python course at the uni). If it's not too complicated and expensive, I might be looking to hire someone to do it.
Edit: I'm not looking for recorded automation, or anything that involves code commands - just simple visual interface and effortless broadcasting across browsers.
All answers and any help will be highly appreciated!
