Backblaze B2 Alternative
A Backblaze B2 Alternative That Bundles the CDN, Upload API, and Access Control
Developer-friendly file storage with CDN, upload API, and access control built in.
Backblaze B2 is the value leader on raw object storage — $6/TB/month ($0.006/GB), with the first 10 GB free, no charge to upload, and a generous 3x free egress allowance (overage $0.01/GB), plus genuinely free egress through CDN partners like the Cloudflare Bandwidth Alliance. If your only metric is cost per stored gigabyte, B2 wins and files.link will not undercut it — so this is not a price fight.
The honest comparison is about everything that surrounds the bytes. B2 is storage and only storage: to deliver files fast worldwide you bolt Cloudflare (or another CDN) in front yourself; to upload you authorize against the S3-compatible or B2 native API and manage application keys and Class B/C transaction limits; and access control means signing URLs or wiring bucket-level keys, which you implement on your side. files.link rolls those three jobs — delivery, a simple upload API, and per-file access control — into the product.
Public files come back as permanent URLs served over a global CDN with nothing to configure; there is no Bandwidth Alliance to join and no CDN distribution to attach to a bucket. Uploading is three HTTP calls with your raw API key in the Authorization header: POST /v1/files/{folderId} returns { success, urls:[{ url, id }] }; PUT the bytes to the presigned url; POST /v1/files/confirm-upload finalizes.
Access control is a public/private flag, not a key-management exercise — private files have no public URL and are fetched through short-lived signed URLs (10-minute expiry) your backend mints per request. There is also a real dashboard with projects and folders, and shareable folder links, which B2's bucket browser does not aim to be. So the decision is about scope.
If you want the cheapest durable bucket and you are happy to assemble the CDN, the upload integration, and the access layer yourself — and especially if you will route egress through Cloudflare for free — B2 is excellent and hard to beat on price. files.link is not S3-compatible and is not the low-$/GB option; it is the choice when you would rather not operate a CDN-plus-storage-plus-signing stack and would take one prepaid balance covering storage and delivery over a per-GB bucket bill plus transaction-class accounting.
For archives there is a cold storage tier; for everything served to users, delivery is already wired.
