How to Search Domain Variations with Copilot
Search domain variations in your IDE with Copilot and ToolRouter.
Tool
Copilot brings domain search directly into your project setup workflow, letting you find and evaluate available domains while scaffolding a new project. Check availability for names that work as both domains and CLI commands, search across developer-friendly TLDs like .dev and .io, and integrate domain selection into your project initialization process. Perfect for developers who want to secure the right name before writing the first line of code.
