once.to

once.to is a URL shortener that creates short, branded links and tracks every click during the redirection process, solving the problem of unreliable visit counting that occurs when ad blockers or privacy-focused browsers block traditional analytics scripts. By counting clicks at the moment of redirection, it captures visits that other tools miss, and its sub-0.07-second average redirection time minimizes visitor abandonment.

The service includes a rule engine that redirects visitors based on country, language, browser, or other criteria, with support for A/B testing through random rule assignment. It offers link statistics, QR codes, custom domains, password-protected links, and an API. Integrations include Zapier, enabling creation of expiring or future short links. Features such as link editing, tags, expiration, custom HTTP status codes, SSL certificates, teams, UTM builder, URL Explorer, and data export are available across plans.

It is designed for individuals and teams who need reliable link management and analytics. A free plan is available, and paid editions—Starter, Pro, Squad, and Enterprise—are offered on a monthly subscription basis with varying limits on link redirects, custom domains, custom slugs, and team members. Additional click bundles can be purchased separately. A free trial is available for the Starter and Pro plans.
