Backblaze B2 vs AWS S3

Backblaze B2 is one of the lowest-priced S3-compatible object storage options available, making it popular for backups, media archives, and cost-sensitive applications. AWS S3 is far more expensive but comes with unmatched ecosystem integrations, compliance certifications, and operational maturity. B2 wins on price; S3 wins on everything else.
