Is homepage://retro a valid URL scheme?

“homepage://retro”
Invalid URL scheme
Confidence: High Checked on May 28, 2026

Usually for websites the protocol is HTTPS or HTTP (its unsecured version). Addressing web pages requires one of these two, but browsers also know how to handle other schemes such as mailto: (to open a mail client), so don't be surprised if you see other protocols.
