Notes

  • Free egress depends on storage: less stored data means less free transfer
  • Class D API calls include 2,500/day free, then cost $0.004 per 10,000 calls
  • Native Backblaze custom domains require sales review and a setup fee and are not included in the free tier. An external CDN custom domain can be considered separately
