The short version

  • Cerebrium is a serverless GPU infrastructure platform; Postman is an API platform for building and using APIs.
  • Free plans on both; paid from $100/mo and $14/mo.
  • Only Cerebrium lists ultra-fast cold starts; only Postman lists API client.
  • Where Cerebrium falls short: free Hobby tier limited to 3 apps and 5 GPU concurrency.
  • Where Postman falls short: free plan limited to single user as of March 1, 2026, making it unsuitable for teams without paid plans.
  • Prices and features on this page were last checked on 13 November 2026.

Cerebrium: How do the cold starts compare to other platforms?

Cerebrium achieves 2-4 second cold starts through memory and GPU snapshotting, significantly faster than traditional 30+ second cold boots. This is competitive with platforms like Beam Cloud.

Source
Postman: Can I use Postman offline?

Postman requires an internet connection to sync collections to the cloud. Since 2023, the Scratch Pad local-only mode was removed. Users must sign in with a Postman account, and collections sync to cloud by default. Offline work is possible but limited without cloud sync features.
