Frequently asked questions
Is Backblaze B2 cheaper than Azure Blob Storage?
Based on the listed entry prices, yes: Backblaze B2 starts at $0 while Azure Blob Storage starts at $1. Actual monthly cost depends on volume and plan tier, so model your real usage before switching. Enterprise quotes can reshuffle the comparison entirely.

Technically you can move between any two tools in the same category, but effort varies: leaving Backblaze B2 is moderate effort at medium lock-in (S3-compatible, portable), and onboarding to Azure Blob Storage involves medium lock-in (Object storage portable via tools). Plan for data export, re-integration, and a parallel-run window rather than a hard cutover.
Which has better developer experience, Backblaze B2 or Azure Blob Storage?
Both Backblaze B2 and Azure Blob Storage score 4/5 on developer experience in our data, so there's no clear winner on that axis alone. The real differentiator usually lands in SDK fit for your language, error handling, and docs depth. A half-day integration spike tells you more than the score.

Yes, Azure Blob Storage targets the same job Backblaze B2 does — image/video heavy applications — so functionally it slots in as an alternative. Pricing model (subscription from $1 vs subscription from $0) and lock-in (medium lock-in (Object storage portable via tools) vs medium lock-in (S3-compatible, portable)) usually decide which is the better fit. Validate on your actual workload. Note: Azure Blob Storage is explicitly not for small projects.
