A company called WunderGraph is offering an alternative to Vercel's storage services, providing a free and open-source solution for serverless Postgres, Redis, and Blob Storage. By using WunderGraph, developers can avoid the premium pricing of Vercel and still access a range of features, including type-safe data fetching hooks, GraphQL operations, and server-side rendering. The alternative uses existing service providers such as Neon for PostgreSQL, Upstash for Redis, and Cloudflare R2 for blob storage, allowing developers to choose their preferred services while avoiding vendor lock-in and markup costs. With WunderGraph, developers can build a unified API exposed over JSON-RPC, integrate with various frameworks, and access data in a declarative and painless manner.
