ThirstyAffiliates

ThirstyAffiliates is one of the longest-running affiliate link management plugins for WordPress, downloaded over 443,000 times, and owned by Caseproof, the same company behind MemberPress and Easy Affiliate. Its core job is cloaking: it turns long, ugly affiliate URLs into short, branded links on your own domain, which both looks more trustworthy to readers and shields your affiliate ID from link hijackers. The Keyword Autolinker lets you set a keyword once and have it auto-link across your entire site, past posts included, without manually inserting links into each piece of content. A Smart Uncloaking feature lets you stay compliant with Amazon Associates' link-display requirements without uncloaking the rest of your link library, and an Automatic 404 Checker flags broken affiliate links before they quietly cost you commissions. Amazon API Importing lets you search and import Amazon products directly inside the plugin, with cloaking, categorization, and geolocation routing applied automatically on import. Pricing runs three tiers by number of sites, all discounted from list price as introductory offers with full-price renewals: Basic (1 site) at $99.60/year, Plus (5 sites) at $149.60/year, and Advanced (10 sites) at $199.60/year, backed by a 14-day no-questions-asked refund guarantee.
