MyChess is free to use and always will be — there's no paywalled tier and no feature held back for payment. It's a hobby project, currently running on free-tier hosting.
If you've gotten value out of it and want to help cover hosting costs as usage grows, you're welcome to leave a one-time tip below. It's entirely optional and comes with no perks or account changes — just a way to say thanks if you'd like to.
Donation link coming soon.
