  • Only Postman lists API client; only Upstash lists serverless Redis.
  • Where Postman falls short: free plan limited to single user as of March 1, 2026, making it unsuitable for teams without paid plans.
  • Where Upstash falls short: HTTP-based REST API only, no TCP connections means higher latency than self-hosted or connection-pooled Redis.
  • Prices and features on this page were last checked on 13 November 2026.
