PageFly vs GemPages vs Replo: The Page Builder Lock-In Test (2026)

Every page builder demo shows you the drag-and-drop. None of them open with the question that matters most three years later: what happens to the pages when you leave? The three leaders answer it completely differently, and that difference is documented in their own help centers. Facts checked June 11, 2026, against each vendor's listing, pricing page, and docs; no referral relationship with any app here.

The lock-in test, answered from their own docs

• PageFly (4.9 stars, 5,682 reviews): uninstalling removes published content from your theme and permanently deletes it, unrecoverable even on reinstall, per its own documentation. Their recommended path is parking on the free plan forever. A recent critical review describes rebuilding 100+ pages after learning this the hard way.
• GemPages (4.9 stars, 3,767 reviews): pages revert to drafts and live pages can break without the app's scripts; an "Uninstall Safely" tool cleans injected code, and reinstalling restores function. Middle of the road: not deleted, not independent.
• Replo (4.7 stars, 175 reviews): output is native Liquid sections in your theme, so pages stay live after uninstall. You lose editing, not the pages. This is the strongest exit posture in the category, with Shogun's stay-as-HTML behavior the runner-up.

If your store treats landing pages as durable assets rather than disposable campaigns, that table alone should weight the decision heavily.

Pricing and where the features sit

GemPages is the value line: unlimited pages and A/B testing for less than PageFly's testing tier. PageFly's strength is ecosystem breadth, with 200+ documented integrations including 32 review apps. Replo's premium buys the Figma-like workflow (real-time multiplayer, design import) and the clean Liquid output; its integration catalog is the thinnest of the three.

The reported complaints

From each listing's recent critical reviews, phrased as reported: PageFly's center on the destructive uninstall and on a theme update incident that altered live stores. GemPages' cite editor-versus-live rendering mismatches and billing after uninstall. Replo's cite the learning curve and support depth against a premium price.

When you need none of them

Any OS 2.0 theme already does sections on every page type in the free native editor, and section libraries (Section Store holds a 4.9 across 2,598 reviews) add individual blocks with no external scripts, no monthly platform fee, and zero lock-in. The honest gate: if your needs are "rearrange sections and fill them well," skip the category. Builders earn their fee when you ship pixel-controlled landing pages and advertorials weekly, need funnel flows, or want testing built into the editor.

Decision rules

1. Durable pages, paid-traffic program, design team in Figma: Replo, priced honestly against its $119 floor. The uninstall posture and multiplayer editing are the real differentiators.
2. Most stores wanting unlimited pages and testing cheaply: GemPages, with a calendar note to use Uninstall Safely if you ever leave.
3. Widest integration surface and template library: PageFly, going in with the exit cost understood: leaving means rebuilding, so commit or don't start.
4. Occasional custom section: no builder. Native editor plus a section library.

Whichever way you build, remember the pages machines read are not the pages shoppers see: landing pages built in any tool still need clean structured data underneath for search and AI assistants to understand them. The free AI readiness check shows what your store currently tells them.
