About Backblaze B2
Backblaze B2 Cloud Storage is an object storage service from the company behind Backblaze's personal computer backup. It offers an S3-compatible API alongside its own native API, so backup tools, NAS devices, media workflows and apps can store data in buckets without code changes beyond an endpoint. Pricing is per terabyte stored with a single always-hot tier, and the first 10 GB is free. Downloads are free up to three times the amount you store each month, and many CDN and compute partners get free egress beyond that. Basic API calls are free for pay-as-you-go accounts, and there are no minimum file size or minimum storage duration fees, unlike several rivals. Capacity can also be bought annually with volume discounts, and a faster B2 Overdrive tier targets AI and high-throughput workloads. It runs as a web service with a browser console and command-line tools. It suits developers, IT teams and creators who want cheap, predictable cloud storage.
Best for: Developers and IT teams who want cheap S3-compatible storage without minimum duration fees.
