He's generally using his own tool called 'manim'. All of his code/animations are open-source. The code for this specific video can be found here: https://github.com/3b1b/videos/blob/master/_2022/wordle.py

There is also the community fork of manim

https://github.com/ManimCommunity/manim/

According to 3b1b on the original repo:

"Note, there are two versions of manim. This repository began as a personal project by the author of 3Blue1Brown for the purpose of animating those videos, with video-specific code available here. In 2020 a group of developers forked it into what is now the community edition, with a goal of being more stable, better tested, quicker to respond to community contributions, and all around friendlier to get started with."
