# sinkto.link

> A free URL shortener with click analytics, QR codes, password-protected links and unlimited team collaboration — plus a hosted MCP server so AI assistants can manage links on your behalf.

sinkto.link is a link management platform for creators, marketers and teams. Short links, analytics and team collaboration are free with no credit card; Pro adds custom domains and custom social previews.
