Buy me a coffee - https://www.buymeacoffee.com/
Buy me a coffee has a similar name to Ko-fi, and the two companies offer many of the same features — for example, donations also default to $3 increments (but you can choose between $1-5). Unlike Ko-fi, Buy me a coffee doesn't have a premium option, but instead monetizes by taking a 5% cut of every transaction, which increases alignment with creators.

Patreon - https://www.patreon.com/

There are 3 tiers of plans for creators to choose from, with lowest level taking 5% and the highest level of service taking a 12% cut of monthly income.
