Why I ask for tips
Hi, I'm Michael. Thank you for being here.
What it costs
| Item | Yearly cost |
|---|---|
| .com domain renewal | About $11 a year |
| GitHub Pages hosting | $0 |
| Model-test API calls | The cost varies, and I have no yearly total to quote. |
I use the Porkbun renewal list price for the domain estimate above, checked October 17, 2026. GitHub Pages hosts the site at no charge.
What tips pay for
- Paying the domain renewal so the calculators stay available.
- Checking provider pricing and correcting the comparison tables.
- Covering the API calls I use for model tests.
Tips unlock nothing, and everyone gets the same free calculators and research.

It is a tip, not a purchase, and you owe nothing for using the site.
