What marketplace development actually requires in 2026
2026 marketplace defaults: Sharetribe Flex (low-code), CocoonFXMedia (custom Postgres + Stripe Connect), or full-custom on Next.js + Postgres + Stripe + Algolia/Meilisearch. Trust + safety stack: Persona (KYC), Sift (fraud), Twilio (verification SMS). Marketplace engineers must reason about two-sided liquidity, escrow flows, dispute resolution, and reputation systems. A "regular SaaS dev" without marketplace exposure typically misses the holdback/payout-delay logic and ships a marketplace where sellers abandon after first dispute.
