A marketplace app with listings, search, payments, and a two-sided trust system
Marketplace apps require buyer and seller flows, search with filters, secure checkout, and the kind of review system that builds trust over time. Goodspeed generates all four, wired together on Supabase and Stripe, ready for a signed App Store release.
WHAT GOODSPEED GENERATES
Ready for every marketplace app build
Every marketplace app app Goodspeed generates can choose from these capabilities, already built and tested.

| Stripe Connect | Stripe Connect Express onboarding for seller payouts with escrow-on-purchase flow. | Included |
| Full-text search | Postgres full-text search with tsvector index on listing title, description, and category. | Postgres FTS |

HOW IT WORKS FOR MARKETPLACE APP
From idea to a live marketplace app app, then the stores
Goodspeed runs a four-stage pipeline: score, plan, build, and ship. For a marketplace app app the pipeline plans 6 capabilities specific to this vertical and builds them on a tested foundation, rather than handing you a shell to complete yourself. The backend gets provisioned during the build and Goodspeed operates it after launch, so you open no infrastructure accounts and configure no servers.
Score
Score your marketplace app idea on a 100-point rubric: demand, willingness to pay, the competition, and the revenue model.
Plan
Generate the full marketplace app architecture spec, screen map, and data schema specific to your idea's unique angle.
Build
TypeScript and React Native code generated on expo, react-native, supabase, with the must-have features on its screens checked against the code before the build is sealed.
Ship
EAS Build compiles iOS and Android binaries. Goodspeed submits a signed build to TestFlight and the Play Console under your own accounts, leaves the release for you to approve, then runs the backend it provisioned during the build (database, auth, analytics), so you open no infrastructure accounts. You own the repo, the signing keys, and the listing.
