Why do people look for Backblaze B2 alternatives?

Most people searching for Backblaze B2 alternatives are not shopping, they already run it and something has stopped fitting.
That something is usually a specific number rather than a feeling.
This page starts from the fields where Backblaze B2 genuinely trails the rosters it appears in, and only then covers the reasons that never show up in a table.

The measured reasons.

Sydney region, No. Wasabi records Yes.
Replication model, single-az, 8th of 12. Tigris records multi-region.

Any one of those is enough on its own if you sized your architecture around it.
None of them is enough if you didn't, which is why the list is short and specific rather than a general case against Backblaze B2.

The reasons that never make it into a table.

A price rise after a funding round.
A licence change that turns a self-host into a subscription.
A region you now need and they do not have.
An acquisition.
A support experience that quietly degrades.
None of those are fields, and all of them move teams, which is why every entry below links back to S3-compatible storage, where the full field set and its sources live.

1.AWS S3

AWS S3, The API everything else copies, and by far the most expensive egress in this roster.
It meets Backblaze B2 in S3-compatible storage.
It is ahead on Sydney region (Yes against No), Official MCP server (Yes against No) and IAM granularity (5 against 3).
What you give up: True cost /mo (USD) ($472.6 /mo, where Backblaze B2 records $26.95 /mo) and Egress $/TB ($90 /TB, where Backblaze B2 records $10 /TB).
Best for workloads already inside AWS where traffic stays on the internal network.
Still the most capable object store, and thirty-eight times Hetzner's cost here, almost entirely bandwidth.

The reference point, not a competitor; run it only if you already operate storage hardware.

Best for EU data residency obligations with a European legal entity behind them.

How this list was built

There is no editorial ranking on this page and no sponsorship behind it. The order is mechanical: every tool that shares a comparison category with Backblaze B2, sorted by how many categories the two overlap in. A tool that meets Backblaze B2 in three rosters sits above one that meets it in a single roster, because more overlap means the comparison is more like-for-like.

The rationale under each entry is composed from the two tools' own cells. Where they differ on a field we score, the sentence names both values and the unit. Where they don't differ, it says so instead of manufacturing a distinction, which is why some entries are short.

Values, sources and verification dates all live on the category tables: S3-compatible storage. If a figure here disagrees with a vendor's current pricing page, the vendor is right and we are stale.

Still deciding whether to move at all? The Backblaze B2 profile has the when-to-use and when-not-to-use blocks, and the Backblaze B2 timeline has the dated changes that usually trigger a migration.
