Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Contentful

  • Pricing model with content type limits (48) forces full tier upgrades
  • Limited GraphQL mutations for content management complexity
  • Requires significant technical expertise and developer dependency
  • Uncertainty following Salesforce acquisition announcement in June 2026

Mercari

  • The flat 10 percent commission plus payment processing fees applies even to very low-value items, so selling something for a few dollars can leave the seller with proportionally little after fees and packaging.
  • Shipping is the seller's responsibility to arrange and package correctly, and disputes over item condition or damage in transit are common friction points in buyer-seller resolution.
  • Instant payout carries its own fee on top of the selling and processing fees already deducted, so getting money out quickly costs more than waiting for standard transfer.
  • Buyer protection and authenticity verification are limited outside the specific luxury authentication programme, so counterfeit risk on unverified categories rests largely on buyer judgement of listing photos and seller ratings.
  • Market depth and typical sale prices vary significantly between the Japan and US versions of the app, and the two operate as largely separate marketplaces despite the shared brand.
