Afternic, owned by GoDaddy, offers a comprehensive domain marketplace with a focus on wide distribution. Their default "Boost" program includes premium placement across their network, though it comes with higher commission rates.

Key advantages of Afternic include integration with GoDaddy's systems, lower minimum commissions, and potential for reduced rates when using their nameservers. However, their standard commission rates are higher than some competitors.

Sedo (Search Engine for Domain Offers) is one of the oldest domain marketplaces. They offer competitive base commission rates and additional services like domain parking and appraisals.

While Sedo's base commission rates are lower, they have higher minimum fees and additional charges for express transfers. Their SedoMLS network provides wide distribution but at a higher commission rate.
