A flexible, domain-first shortener with generous domain allowances, favored by power users.
Short.io is a domain-first shortener that power users like for its flexibility and an unusually generous free tier, with five custom domains and unlimited analytics retention even before you pay. If hosting many branded domains cheaply is your priority, Short.io is strong. Its trade-offs: no link-in-bio pages, no bot-click filtering, and a paid plan at $18 a month billed monthly, versus ReSlug's $9 monthly or $6.60 on annual billing. ReSlug matches Short.io on branded links, real-time geo and device analytics, custom QR codes, link expiration, scheduling, and password protection, and adds bio pages and bot filtering. For most marketers ReSlug delivers the same core capability for half the monthly price; for domain-heavy power users, Short.io's free tier is worth a look.
