Trustpilot vs Trustmary vs Stamped.io for online stores is a shorthand for three different paths merchants take to collect social proof: a public review marketplace, an NPS-and-testimonial engine, and an ecommerce-native reviews platform. Pick based on what you need to show shoppers, how much control you want over data and branding, and how deep you need your integrations to be.
Trustpilot
Features and functionality
Trustpilot is primarily a public consumer review platform that lets any verified customer post star ratings and long-form reviews on a brand profile, and it exposes that content to search and third-party discovery. It emphasizes site-level trust signals and profile-level SEO, plus widgets you can embed on product or site pages. It also offers review invitations, moderation tools, reply workflows, and marketing assets to surface reviews externally. (business.trustpilot.com)
Pricing approach
Trustpilot provides a free basic account for collecting a modest number of reviews plus tiered business plans for more volume and features, sold per domain with annual commitments on paid tiers. Paid tiers are presented as Starter, Plus, Premium, and Enterprise, with starting prices listed on their pricing page and Enterprise available by quote. If you need exact monthly prices for a particular plan or domain count, see Trustpilot’s pricing page and request a demo or quote. (business.trustpilot.com)
Ease of setup and use
Claiming a profile and collecting a few reviews is straightforward; the free flow is usable immediately. Paid features and domain-level contracts add administrative overhead, especially for multi-store setups since domains are priced separately. Trustpilot’s strength is simplicity for public reputation but it is less focused on deeply branded on-site widgets without a paid plan. (business.trustpilot.com)
Integrations
Trustpilot lists integrations with common marketing and CRM tools and provides widgets and APIs to syndicate reviews into your storefront and ad channels. Its documentation and prebuilt connectors make it workable with many stacks; for specific platform plugins check their integrations list and the product pages. (business.trustpilot.com)
Customer support and documentation
Support is tiered by plan. Free accounts get access to the Support Center; paid customers receive more hands-on help and additional features. The public documentation is extensive, but hands-on onboarding is gated behind paid tiers or sales conversations. (business.trustpilot.com)
Pros and cons
Pros: Widely recognized by consumers, drives third-party discovery, quick to start collecting brand-level reviews. (business.trustpilot.com) Cons: Paid plans are per-domain and contractual, product-level reviews and deep customization often require higher tiers or add-ons, and the platform’s public nature means you have less control over which reviews appear where. (business.trustpilot.com)
Best for
Brands that want public discoverability and a centralized reputation visible across search and marketplaces, and merchants that prioritize third-party validation over fully branded on-site experiences. (business.trustpilot.com)
Trustmary
Features and functionality
Trustmary is built around collecting NPS, CSAT, and testimonial responses and turning positive feedback into website testimonials, review widgets, and a hosted review page. It focuses more on controlled feedback flows and harvesting qualitative testimonials you can publish, including video. It positions itself as a testimonial and feedback platform that also supports review imports from other services. (trustmary.com)
Pricing approach
Trustmary uses a usage-based and tiered pricing model with a free tier that includes a small monthly allowance of survey responses and widget views, and paid tiers that scale by responses and widget views. They publish example prices and a configurable build-your-plan option, plus add-ons for whitelabeling, integrations, and premium features. Pricing is modular so you can craft plans aligned to response volume and site widget traffic. (trustmary.com)
Ease of setup and use
Trustmary is straightforward to set up for basic testimonial capture and widget embedding; forms and survey templates are built-in. Because it is focused on NPS and testimonial flows rather than open consumer reviews, configuration tends to be lighter for teams that want controlled, high-quality quotes rather than a continuous stream of public ratings. (trustmary.com)
Integrations
Trustmary supports integrations through Zapier and direct premium integrations with CRM systems like HubSpot and Pipedrive, plus connections for importing reviews from Google, Facebook, and other platforms. Premium integrations are an add-on in higher tiers. (trustmary.com)
Customer support and documentation
Trustmary provides documentation and a Help Center, with premium support and onboarding available as paid add-ons. The model assumes many customers will want consultative onboarding for testimonial strategy, which is reflected in optional onboarding fees. (trustmary.com)
Pros and cons
Pros: Strong at converting NPS and survey responses into publishable testimonials, modular pricing if you only need a small number of responses, and native support for video testimonials. (trustmary.com) Cons: Not a public review marketplace, so it will not drive third-party discovery; some useful integrations are gated behind paid add-ons; heavy site traffic can push you into higher view tiers. (trustmary.com)
Best for
Service businesses and ecommerce merchants that want curated testimonials, high-control NPS workflows, or to convert promoters into marketing assets without the noise of an open review platform. For merchants comparing testimonial-focused apps, see the Trustmary vs Okendo vs Fera comparison. (trustmary.com)
Stamped.io
Features and functionality
Stamped is an ecommerce-oriented reviews, NPS, and loyalty vendor that collects product and site reviews, supports photo and video UGC, runs NPS surveys, and bundles loyalty and lifecycle tools if desired. It is explicitly positioned for order-volume billing and product-level reviews integrated into product pages and ad syndication. (website.stamped.io)
Pricing approach
Stamped’s published pricing is product-based and built around monthly order volume, with self-serve plans available through app stores and higher tiers available for larger order volumes. The vendor publishes starter prices for its products and encourages building a bundle that matches order volume; enterprise-level quotes are available. If you base selections on order counts, check their order-volume calculator or Shopify App listing for the self-serve plans. (website.stamped.io)
Ease of setup and use
For Shopify merchants, the Stamped app is designed to be plug-and-play with templates for in-email and on-site collection. Basic setup can be fast; deeper customizations and bundling with loyalty or lifecycle features will take more hands-on configuration. Documentation and a help center support migrations from other review providers. (website.stamped.io)
Integrations
Stamped emphasizes ecommerce integrations, naming Shopify and Shopify Plus, and marketing integrations such as Klaviyo, Attentive, Gorgias, and social syndication to Meta and Google. It also provides CSV import tools and migration help to bring reviews from other platforms. (website.stamped.io)
Customer support and documentation
Stamped publishes a comprehensive help center with billing and migration guides, plus onboarding support options. Support channels and response levels vary by plan; they advertise 7-day-per-week availability for support contacts and specific onboarding assistance for larger customers. (website.stamped.io)
Pros and cons
Pros: Built for ecommerce stores with product-level reviews, granular order-based pricing, and multiple retention features available if you want loyalty and lifecycle alongside reviews. (website.stamped.io) Cons: If you need broad public discovery outside your brand’s site, Stamped is less of a public marketplace than Trustpilot; pricing is tied to order volume so growing merchants must watch how order counts affect monthly costs. (website.stamped.io)
Best for
Shopify merchants and brands that want product-level reviews, photo/video UGC, and integrated loyalty or lifecycle tools, while keeping reviews primarily owned and displayed on their own storefront. (website.stamped.io)

Situational Recommendations
If your priority is public discovery and third-party validation, pick Trustpilot. It is the recognizable, consumer-facing review profile that lives off-site and can improve trust signals for ads and organic search. Expect per-domain pricing and a model that rewards brands wanting public visibility. (business.trustpilot.com)
