Calcuris runs on your own machine — the client starts it, so there is no endpoint to ping. 53 installs a week from npm. Last commit 13 Jul 2026.
Tax calculators for US, UK, Canada, Australia: income tax, property tax, stamp duty.
Today is the operative word: we check Calcuris every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
