8 Best Backblaze B2 Alternatives (2026)
The closest alternatives to Backblaze B2 are AWS S3, Bunny Storage, Cloudflare R2 and DigitalOcean Spaces, with 4 more below. Each shares a comparison category with it, so every rationale here names both tools' real values. Backblaze B2 is marked No on Sydney region, where Wasabi records Yes — usually where a switch starts.
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, so 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. The ones we catch get logged on the Backblaze B2 timeline.
How the shortlist is ordered. Every tool below shares at least one comparison category with Backblaze B2, sorted by how many categories the two overlap in. There is no editorial ranking, no sponsorship and no affiliate link — the order is the overlap count, and the rationale under each is generated from the two tools' own cells, so it names real values rather than adjectives.
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 by a wide margin, and thirty-eight times the cost of Hetzner on this scenario almost entirely because of bandwidth. Stay on S3 if you genuinely use Object Lock compliance mode, Access Points, cross-region replication or IAM condition keys; otherwise you are paying $441 a month for an API you can get elsewhere.

2.Bunny Storage
Bunny Storage — Edge storage built as a CDN origin, with its own API rather than a faithful S3 one. It meets Backblaze B2 in S3-compatible storage. It is ahead on Sydney region (Yes against No), Replication model (multi-region against single-az) and TTFB from Sydney (20 ms against 180 ms). What you give up: Versioning (No, where Backblaze B2 records Yes) and Object lock / WORM (No, where Backblaze B2 records Yes). Best for static sites, images and video served to a global audience through Bunny's CDN. Included because people shortlist it against S3 providers, but it is a CDN origin with storage attached rather than an object store with a CDN attached. Superb Sydney delivery; do not expect S3 semantics, and read the regional egress table before modelling the cost.

3.
Cloudflare R2
Cloudflare R2 — S3-compatible object storage with zero egress fees, on Cloudflare's network. It meets Backblaze B2 in S3-compatible storage. It is ahead on Official MCP server (Yes against No), Sydney region (Partial against No) and CDN integration (free-bundled against partner). What you give up: Versioning (No, where Backblaze B2 records Yes) and Class A $/M ops ($4.5 /M ops, where Backblaze B2 records $0 /M ops). Best for public assets, media and package registries where egress dwarfs storage. The default answer for anything read-heavy, and the only provider here where egress genuinely stops being a line item you have to model. Watch the $4.50 per million Class A charge on write-heavy workloads, remember that 'Oceania' is a hint rather than a region, and check that you are not quietly depending on versioning — R2 does not implement it, which is a bigger gap than the zero-egress headline lets people notice.

DigitalOcean Spaces
DigitalOcean Spaces — Bundled object storage plus free CDN, priced as a flat base fee with overages. It meets Backblaze B2 in S3-compatible storage. It is ahead on Sydney region (Yes against No), TTFB from Sydney (25 ms against 180 ms) and CDN integration (free-bundled against partner). What you give up: Versioning (No, where Backblaze B2 records Yes) and Object lock / WORM (No, where Backblaze B2 records Yes). Best for static assets and user uploads served from Sydney with a bundled CDN. Buy it for the bundling and the Sydney region, not the feature set. No versioning and no bucket events rules it out as a system of record; as a CDN-fronted asset bucket sitting next to your Droplets it is genuinely convenient and hard to misbudget.

Hetzner Object Storage
Hetzner Object Storage — The cheapest credible S3 endpoint in Europe, with a deliberately thin feature set. It meets Backblaze B2 in S3-compatible storage. It is ahead on GA year (2024 against 2015) and Egress $/TB ($1.38 /TB against $10 /TB). What you give up: Object lock / WORM (No, where Backblaze B2 records Yes) and Event notifications (No, where Backblaze B2 records Yes). Best for CI artefacts, build caches and cold backups where the bill is the point. Wins the headline number by a mile and loses the feature comparison by a similar margin. No object lock, ambiguous versioning, no notifications, no APAC location, no published durability figure — brilliant for build caches and cold backups, wrong for a system of record.

6.iDrive e2
iDrive e2 — USD 4/TB S3-compatible storage with zero-egress marketing and a fair-use cap. It meets Backblaze B2 in S3-compatible storage. It is ahead on GA year (2021 against 2015), Egress $/TB ($0 /TB against $10 /TB) and Storage $/TB/mo ($4 /TB/mo against $6.95 /TB/mo). What you give up: Event notifications (No, where Backblaze B2 records Yes) and CDN integration (none, where Backblaze B2 records partner). Best for backup and MSP workloads where storage volume dominates and reads are rare. The cheapest storage rate here alongside Storj, with object lock included, and the least legible egress terms in the roster — legible enough that we will not put a number in the cost column for it. Fine as a backup target, where you store far more than you read; do not build a public asset pipeline on a fair-use cap you cannot find written down.

MinIO
MinIO — The self-hosted S3 reference implementation — your hardware, your bandwidth, your SLA. 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: CDN integration (diy, where Backblaze B2 records partner). Best for on-premises or air-gapped deployments where data cannot leave your control. The reference point rather than a competitor: it shows you what full S3 fidelity looks like and therefore what you are giving up when you buy cheap. Worth running only if you already operate storage hardware — and note the community build lost its admin console in 2025, which changed a lot of people's assumptions about what 'free and complete' meant. Note that we carry MinIO as the do-it-yourself baseline in that roster — the "what if we just ran this ourselves" reference point. The honest answer is usually that it is cheaper and considerably more work.

Scaleway Object Storage
Scaleway Object Storage — European-sovereign S3 storage with multi-AZ classes and a real IAM system. It meets Backblaze B2 in S3-compatible storage. It is ahead on IAM granularity (4 against 3), CDN integration (first-party-paid against partner) and Replication model (multi-az against single-az). What you give up: Storage $/TB/mo ($16.94 /TB/mo, where Backblaze B2 records $6.95 /TB/mo) and TTFB from Sydney (300 ms, where Backblaze B2 records 180 ms). Best for EU data residency obligations with a European legal entity behind them. The most feature-complete of the non-hyperscalers — genuine IAM, multi-AZ placement, object lock, real lifecycle rules — and irrelevant for Australian traffic at 300 ms away. Pick it when EU data residency is a requirement rather than a preference.

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.
