Before you buy
What happens after I pay?
Dodo brings you back here. We verify your payment and try to activate Pro in the installed extension automatically. Your receipt includes a backup license key.
Is this a subscription?
No. This is a one-time purchase for a lifetime Pro license. Dodo displays any applicable taxes and the final total before you pay.
Can I use a different browser?
Activation belongs to a browser installation. Remove the license from Settings while online to release that activation, then activate it in the other browser. License limits are set on the purchased product; keys do not sync through your Chrome account.
What if activation cannot connect?
Keep your receipt. Copy its key into Alt DevTools → Settings → License and select Activate, or use the activation form on this site. You do not need to purchase again.
