Chess.com or Lichess?
You can do this after every game, no paid membership required.
A lot of members don't use this, though - they seem to think that "Game Review" is the only option ...
Free chess analysis on chess.com seems to have been abolished. Recently I have not been able to get it.

Free analysis is still there. They just changed it from an "Analysis" button to a simple icon (a magnifying glass with a checkerboard pattern):

Chess.com:
Pluses - not an inflated rating
Minuses - not free
lichess.org:
Pluses - free
Minuses - inflated rating
Also, idk if this is something but usually when I play on lichess I play way better then on chess.com. This may be influentiated by the simple GUI of the lichess, while the GUI of the chess.com is kinda distracting. But that's only my opinion..
i like both
