Will it slow my store down?
No, and this is where Redspot is genuinely different. Recording runs inside Shopify's web pixel sandbox, off your store's main thread, and the only script that touches your pages is 2.4 KB compressed. Tools that record on the main thread are the ones shoppers feel.
What about visitor privacy and GDPR?
Everything sensitive is masked in the visitor's browser before it's ever sent: typed values are bulleted, sensitive fields are redacted, clipboard is never recorded. Recording is consent-gated through Shopify's customer privacy API, and the mandatory GDPR webhooks (data request, customer redact, shop redact) are implemented.
Does it work with my theme?
Yes. Redspot reconstructs pages from the DOM itself rather than per-theme templates or screenshots, so it works across themes, including Online Store 2.0 and Horizon, and it keeps working when you redesign.
Do I need Shopify Plus?
No. Sessions, heatmaps, attribution and the full checkout funnel work on every plan. Pixel-level replay inside checkout pages specifically is the one thing Shopify gates to Plus. The funnel data still flows either way.
