Screen recording?

Question

Video

For a long time, the most convenient service prntscr.com and the like have already appeared, which greatly simplified the work.
Often there is a need to make such a video. About a month ago I came across a service similar in terms of convenience and principle of operation, but did not have time to write down a link for myself.
Maybe someone knows such a service?
Screen-O-Matic and the like, please do not offer!
Requirements:

• work from the browser or from the system
  
• ease of handling
  
• sharing and saving
  
• Mac OS version - if from the system
  

Thank you in advance!
