Cloud Object Storage Providers in 2026
A practical overview of three S3-compatible object storage and CDN platforms that shape how engineering teams host assets, archives, and application data outside the hyperscaler storage tier.
Object storage quietly became the default place to put anything that is not a row in a database. User uploads, build artefacts, media libraries, data-warehouse snapshots, and cold archives all end up behind an S3-compatible endpoint of some kind. The three providers in this review are not trying to replace Amazon S3 or Google Cloud Storage in their native habitats; they compete on a different axis — predictable egress, simpler pricing, regional presence, or the tight coupling of storage to a content delivery network.
Two of them — Wasabi and Backblaze — are independent hot-storage providers that differ in how they position themselves (pure storage versus storage plus consumer backup), while Bunny.net combines storage with a globally distributed CDN designed to serve that storage quickly. The review looks at each through the same lens: S3 compatibility, regional footprint, integrations, and the adjacent services that surround the bucket.
Each platform is evaluated on what engineers actually care about when wiring it up: which SDKs and tools understand it out of the box, how reliably objects land in a second region, and what operational ceremony is required to hand a team a bucket.
Providers
Bunny.net
Storage tightly integrated with a global content delivery network.
Bunny.net started life as a content delivery network with a reputation for straightforward configuration and good latency in markets under-served by the larger CDNs. Over time it grew into a broader platform, adding object storage, a DNS service, and a streaming-video component. The storage offering, Edge Storage, is less interesting on its own than in combination with the CDN: a bucket in one region can be paired with a Pull Zone and served from points of presence on six continents, with replication to additional regions configured from the dashboard.
For applications where the storage and delivery concerns overlap — static sites, media libraries, image-heavy e-commerce catalogues — using one vendor for both reduces a lot of glue. The CDN layer supports rule-based caching, edge scripting through a V8-based runtime, and the usual knobs around WAF, rate limiting, and origin shielding.
For workloads that are purely "put objects and read them back," Bunny.net will feel like a reasonable option, but the combination with its CDN is where the product most clearly differentiates itself.
Wasabi
S3-compatible hot object storage aimed at predictable economics.
Wasabi's pitch is straightforward: a single storage tier (no distinct cold class), S3-compatible endpoints, and a pricing model that aims to be predictable rather than variable-by-access-pattern. Engineers working with Wasabi typically point existing S3 SDKs at a custom endpoint, hand over credentials, and find that most tooling — AWS CLI, MinIO, rclone, Veeam, Restic, Duplicati — works with minimal adjustment.
The feature set is deliberately narrow: Wasabi does not ship its own CDN, its own serverless compute, or a portfolio of adjacent services. What it does well is store objects with S3 API semantics, offer immutability and object lock for compliance workloads, and replicate across regions for teams that need geographical redundancy without piecing it together themselves.
Because the API surface tracks S3 closely, migrations in either direction are usually a matter of changing endpoint URLs and credentials. This makes Wasabi a reasonable second target for teams who want an alternate location for backups and archives without rearchitecting their storage access code.
Backblaze
B2 Cloud Storage paired with a long-running consumer backup business.
Backblaze is the most unusual entry in this set because it carries two products under one brand. The developer-facing product, B2 Cloud Storage, is an S3-compatible object store sold directly to engineering teams. Alongside it is Computer Backup, a veteran consumer offering that quietly funded the operational muscle behind B2 for most of Backblaze's history.
For developers, the practical story is similar to Wasabi: a single storage class, standard S3 semantics, and a broad integration surface. What sets B2 apart in day-to-day use is the ecosystem around it — Cloudflare's bandwidth alliance removes egress fees when B2 is served through a Cloudflare property; tools like rclone, Restic, and Veeam list B2 among their first-tier targets; and the application key model is granular enough to issue narrow credentials for specific buckets or prefixes.
For teams that want durable storage with well-supported tooling and a long operator record, B2 is a reliable pick. The consumer backup product is tangential to most developer workloads but worth knowing exists — it is what keeps the provider's storage fleet well-exercised.
Feature comparison
The matrix below summarises the practical differences between the three providers. The CDN column reflects whether a globally distributed delivery network is part of the same product (not whether one can be bolted on).
| Provider | S3 compatibility | Integrated CDN | Storage classes | Object lock / immutability | Regions |
|---|---|---|---|---|---|
| Bunny.net | S3-compatible endpoint on Edge Storage | Yes, globally distributed Pull Zones | Single hot tier with optional replication | Versioning; immutability via configuration | Storage regions across three continents |
| Wasabi | Close S3 parity | No (bring-your-own) | Single hot tier | Native object lock for compliance scenarios | North America, Europe, Asia-Pacific |
| Backblaze B2 | Native B2 API plus S3-compatible endpoint | No (strong Cloudflare integration) | Single hot tier | Native object lock | US regions and EU region |
How to choose
The choice between these three rarely comes down to raw storage price; most teams reach for one or another based on what surrounds the bucket.
For workloads that are dominated by read traffic to end users — a media library, a static site, an e-commerce catalogue — Bunny.net minimises the number of vendors involved. The CDN and storage are designed to work together, and the configuration overhead is modest.
For backup and archive workloads, or for any application where the access shape is closer to "periodic ingest, rare retrieval," Wasabi and Backblaze B2 are the strongest candidates. Wasabi tends to win on pure economics for stable, predictable workloads; Backblaze is the more natural pick when Cloudflare already sits in front of the application, or when the team relies on backup tooling that lists B2 as a first-tier destination.
A common pattern in practice is to combine two of these providers — one as a primary for live serving, another as an off-site mirror for disaster-recovery purposes. Because all three speak a variant of S3, the operational cost of maintaining a second target is unusually low.
