PageGains, a conversion rate optimization tool, was announced by Jon (@jonbuildshq) in a post on X as a landing-page roast tool for $3.99. Users submit a URL and receive an AI-generated report with 10–20 ranked conversion issues and fixes.
The $4.99 single-audit price listed on the site differs from the $3.99 price stated in the announcement post. Jon wrote that the tool is "cheaper than your coffee and meaner than your cofounder."
PageGains offers a free preview that includes a conversion score and one issue before payment is required for the full report. The preview does not require a credit card.
The site also lists credit packs of five audits for $12.99, 20 for $37.99 and 50 for $59.99. It attributes the product to "Jonathan" and references the @JonBuildsHQ account as its builder.
In an Indie Hackers post, Jon reported $159 in early sales from 21 customers and said most customers came from replying to founders' posts on X rather than broadcasting his own launch. A PeerPush listing, published April 25, 2026, categorized PageGains under AI / Product Marketing and said the builder self-reported $100 in monthly recurring revenue at the time. The listing identifies the builder as Jon Builds (@j2fbinfo) and shows PageGains as the account's only product on the platform.
