Searching through expired domain names is a great way to find a professional yet affordable domain for a new project or business, but the best ones are usually snagged quickly.

I built this free tool out of necessity for my own side projects, to help me catch a relevant, recently expired domain at TLD base price. Domain Heist sends a daily summary of expired domains that match your search criteria. It's perfect for when you have an idea of what you're building but haven't decided on the exact name.
