MillionVerifier details from their public pages as of October 30, 2026, in their listed currency. “Not stated” means we could not find it published, not that it is missing. MillionVerifier is a trademark of its owner and is not affiliated with VeriDock.
Each row uses the same volume on both sides. VeriDock prices are the cost of one month on the cheapest plan that covers it, including any overage. MillionVerifier prices are one-time packs: you pay once and the credits stay until used, so a one-off clean compares directly, while a recurring volume means buying again. Compare any volume in the calculator.
