Our system updates daily, ensuring that you always have access to fresh opportunities before others find them.

ComDetector doesn’t just check domain availability — it identifies unregistered .com domains that already have related names registered across 1,500+ TLDs. That means these domains show signs of interest or usage, making them more strategic opportunities.

Our domain and TLD registration data is updated daily, so you’re always working with fresh, current insights on which .com names are still unregistered.
