This mod adds discord rich presence for noita!
It shows:

• Your health.
• The biome your in.
• Time since you started the run.
• When you hover over the gold icon it shows your gold.
• When you hover over the noita image it shows if your in a regular run, a daily run, or new game+ including the cycle.

There are two downloads, one for the regular version which sends updates to discord every second and one for a performance version which sends updates once every 15 seconds.
I do not know if the original version even has any performance impact but if you feel like it does the performance version should be better for you.
