Developer Builds Sanity-Powered Repost Marketplace Showcase Without a Full Backend

A developer built Pulse Wall, a content-driven spin-off of Pulse — a social promotion marketplace where businesses run repost campaigns and promoters earn money — using Sanity as the content layer instead of a traditional backend. The project was submitted to the Sanity Challenge under Path Two and reuses an existing Next.js UI with Tailwind and shadcn/ui components, replacing backend services like authentication, payments, and a Go API with Sanity's Content Lake and Studio. Campaign listings and promoter spotlights are managed entirely through Sanity Studio, embedded directly into the app, allowing content updates without redeployment. Key technical hurdles included resolving CORS errors for Studio API calls and fixing a Next.js static prerendering issue where new Sanity content wasn't appearing live until dynamic rendering was enforced in the correct file. The app is deployed on Render with a GitHub Actions workflow pinging the free-tier instance every five minutes to prevent it from spinning down.
