Swell review

Swell ranks tenth because it brings headless flexibility to brands at the lower end of enterprise, with prices you can read before you call. Merchants can launch on hosted storefronts with themes, including uploaded Shopify themes, or run a headless front end hosted anywhere. Swell Checkout covers guest checkout and abandoned cart recovery, and higher plans add international price lists, advanced reports, role-based permissions, developer support and a 100% uptime SLA. Starter costs $29 a month billed yearly, Standard $299 and Unlimited $2,250, with a custom plan for merchants doing over $10M a year. The catch is the revenue ceiling on each plan: once trailing 12-month sales pass it, Swell charges a fee from 2% on Starter to 0.4% on Unlimited. API requests, function calls and storage are also metered. For a true enterprise volume you will be on the custom plan, so treat Swell as a mid-market pick.
