Chesscom2Lichess por Matteo Golinelli

An open-source extension that adds a button to the game page (once it's finished) to automatically send the game to the amazing Lichess analysis page.

I know that it's better to play on Lichess, but sometimes you might want to (or have to) play on Chess.com. Since Chess.com analysis is paid and far from perfect, this extension will help you to analyse your games on Lichess.
