When to pick Nhost

If you want GraphQL-first Postgres with realtime subscriptions out of the box, Nhost's Hasura integration is the easiest path.

  • Your team is SQL-native and needs relational joins.
  • Your team is already invested in Nhost's SDK and ecosystem.

When to pick kynetradb

  • You want a comparison-led conversation about BM25 full-text, vector evaluation, and data-plane trade-offs.
  • You need a product-specific implementation scope rather than a generic migration claim.
  • You want to assess 19 hosting target profiles, including 5 Indian providers.
  • You want a scoped preview conversation about the data, deployment, and operating boundary.
  • You want a single binary with no runtime dependencies — no container fleet to operate.
