How we grade them
| 2.6GPAREVIEWS.ioGood | 1.8GPAStampedWeak | |
|---|---|---|
| Value for money | BEssentials covers up to 300 invites, so a 300-order shop pays $23 a month billed yearly, or $29 monthly. Set against its listed rivals at that size, that's the cheap end. Rich snippets and Seller Ratings start at Start-Up, $63 yearly ($79 monthly), and each country domain is billed apart. | DAt 300 orders a month you're past the $23 plan's 200-order cap, so it's Reviews (1k) at $99 a month, with the same features as the $23 plan. Set against its listed rivals at that size, only Okendo costs more. And every order counts toward the cap, even when no request is sent. |
| Free plan and trial | CNo free plan. There's a 14-day free trial, and the listing doesn't say whether it wants a card. Fine for watching a few invites go out, not for living on. | FNothing free: no free plan and no trial on its Shopify listing. Stamped says reviews only show in its widgets on a paid plan, so you're paying from day one. |
| Features | BThe whole job and a bit more: product and company reviews in one request, photo and video, 15+ widgets, email and text invites, Google Seller Ratings, imports, surveys, and on Grow a reputation manager with competitor analysis. AI replies and translation wait for Plus. | BThe whole job: requests by email and text, reviews written inside the email, photo and video reviews, Q&A, Google Shopping and rich snippets, imports, and sharing reviews across grouped products or stores. Loyalty, referrals and VIP tiers are there too, on their own plan. |
| Ease of use | CNo store rating on record. You connect your store, set up invites and pick widgets, and the yearly plan is chosen in the dashboard after signing up. Moving up the plans means watching how many invites you send. | CNo store rating on record. It installs from the Shopify App Store and sends requests after each order, but you still pick widgets, set up the emails and texts, and keep an eye on the monthly order cap. |
| Platforms and integrations | BWeb, with Shopify, BigCommerce, Klaviyo, Gorgias, Attentive, Dotdigital, Bazaarvoice and Google. The API is only on Plus. No phone or desktop app is listed. | BWeb, with Shopify, Klaviyo, Gorgias, Recharge, Shopify Flow, Google Shopping, Facebook and Instagram. Stores on other platforms are pointed to stamped.io.

Who each one suits
REVIEWS.io
- Online stores that want product reviews and Google Seller Ratings together
- Brands running email and SMS through Klaviyo or Attentive
- Stores moving from Yotpo, Okendo or Trustpilot that need reviews imported
Stamped
- Shopify stores that want product reviews and a loyalty program from one vendor

Worth knowing
REVIEWS.io
- There is no free plan on the pricing page; Essentials, from $23 a month on yearly billing, is the entry point.
- Price follows review invites sent: each email or SMS request counts once, and more invites move you up a price step.
- Each top-level domain is a separate subscription, so stores in several countries pay for each one.
- Google Seller Ratings start at Start-Up; AI replies, translation and API access need Plus.
Stamped
- There is no free plan any more: Stamped says reviews only show in its widgets on a paid plan.
- Every order counts toward the monthly limit, even with no request sent; at the limit, requests queue until you upgrade or the month resets.
- Loyalty is billed apart from reviews, from $299 a month; the Full Suite plan that combines them has no price on the Shopify listing.
- These prices are from Stamped's Shopify App Store listing; stores on other platforms are pointed to stamped.io for their options.
