In contrast, Porkbun requires customers to provide their accurate personal information during the registration process to comply with ICANN regulations.

Porkbun, on the other hand, offers competitive pricing for domain registration but charges extra for WHOIS privacy protection and other add-on services.

4. User interface: Njalla has a minimalistic and straightforward user interface designed for privacy-conscious users. Porkbun offers a more feature-rich user interface with advanced tools and customization options for managing domains.
