The best object storage provider for a small team is the one whose charges for data leaving the bucket and for API requests suit how your app reads files, because those lines decide the bill. Compare hyperscalers, egress-free specialists, regional clouds and self-hosted options, then test S3 compatibility with your own tools before you move anything.
Storing a file is the easy part of the bill. The lines that decide it are what leaves the bucket, how often your app asks for things, and how quickly you'll want files back, so read those lines on every provider's page before you look at the storage line. Below are nine providers, in no particular order, for developers and small teams keeping backups, media or app data.
What decides the bill
Think about the shape of your traffic first. A backup bucket that's written nightly and almost never read behaves very differently from a media bucket serving images to thousands of visitors. With backups, the stored volume matters most. With media and app data, the charges for data leaving the bucket and for requests usually grow fastest, and they're the lines people skip.
Some providers build their pitch around exactly that. Cloudflare R2's page leads with zero egress fees, and Wasabi's page says there are no fees for egress or API requests. These are vendor claims, not guarantees about your use. Read the fair-use terms behind them, check what happens if you read far more than you store, and ask about minimum storage periods before you plan around a promise.
Then write down three numbers for your own app, from your current logs: how much you store, how much leaves each month, and roughly how many requests you make. With those in hand, any provider's charges page turns into a quick sum rather than a guess.

Storage providers A to Z
One line each on what the provider is for.
Amazon S3
Best for: Teams already on AWS storing data lakes, app files, backups and archives in the format other providers copy when they say S3-compatible.
Backblaze B2
Best for: Backups, media archives and data-intensive AI work on capacity object storage; the vendor claims no lock-in. Free tier start, no card (as of Nov 2026).
Cloudflare R2
Best for: Apps serving lots of reads that want S3-compatible APIs, from a vendor that claims zero egress fees. Start free, no card (as of Nov 2026).
DigitalOcean Spaces
Best for: Developers already on DigitalOcean who want S3-compatible object storage with a built-in CDN included.
Google Cloud Storage
Best for: Projects on Google Cloud that want storage with multiple redundancy options, available virtually anywhere.
Hetzner Object Storage
Best for: European teams with GDPR needs; the vendor claims GDPR compliance and 100 percent green electricity for S3 storage that grows with you.
MinIO
Best for: Engineers who'd rather run S3-compatible storage themselves, including for AI training, inference and agents.
Tigris
Best for: Multi-cloud apps that need S3-compatible object storage for any cloud, from a vendor claiming you pay nothing to move data out.
Wasabi
Best for: Organisations storing large volumes that like paying for what they store; the vendor claims no fees for egress or API requests. 30-day free trial (as of Nov 2026).
Hyperscalers
Amazon S3 is cloud object storage for data lakes, apps, backup and archive, and it's the format everyone else copies when they say S3-compatible. Google Cloud Storage offers multiple redundancy options and runs virtually anywhere. If the rest of your stack already lives on one of these clouds, keeping storage there keeps permissions, logging and support in one place. If you're weighing a move off the biggest cloud altogether, my guide to AWS alternatives looks at whole platforms rather than storage alone.
Low-charge and egress-free specialists
These providers do storage and little else. Backblaze B2 is capacity object storage aimed at AI and data-intensive workloads, backups and media archives, and the vendor claims no lock-in; as of Nov 2026 its page says you can start on a free tier with no credit card. Tigris offers S3-compatible object storage for any cloud, and the vendor claims you pay nothing to move data out, which suits apps spread across more than one provider. The two egress claims discussed above sit in this group too.
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
Specialists can make a lot of sense for backups and media, where you don't need the long list of other services a big cloud offers. The trade is one more account, one more set of keys and one more support desk.
Regional clouds and self-hosted storage
DigitalOcean Spaces is S3-compatible storage with a built-in CDN, a natural fit if your servers already run on DigitalOcean. Hetzner Object Storage claims GDPR compliance and 100 percent green electricity, which matters to European teams; my comparison of Hetzner and DigitalOcean covers the two clouds more widely, and my list of Vultr alternatives looks at other smaller hosts.
MinIO is the self-hosted route: S3-compatible object storage you run yourself, now pitched for AI training, inference and agents. You control the hardware and the data, and you also own the upgrades, the disks that fail and the backups of your backups.
S3-compatible doesn't mean identical
Most of the regional, specialist and self-hosted options here describe themselves as S3-compatible. That usually means the basic calls work with the same libraries and tools. It doesn't promise that every feature your app relies on behaves the same way: lifecycle rules, versioning, object locking, presigned links, event notifications and storage classes can all differ, or be missing.
So test with your exact tools. Point your backup software, your app's upload code and any command-line scripts at a trial bucket, and run the features you use, not just an upload and a download. If you're serving files to visitors, check whether you need a separate CDN in front; my guide to CDN providers covers that layer.
My advice on keeping storage bills predictable
Match the provider to how your data moves, not to the storage headline. If you mostly write backups and rarely read them, a storage specialist is the obvious place to start. If you serve lots of reads, the egress-free claims are worth testing hard against their terms. If everything else you run is on one big cloud, staying put may save more time than switching saves on the bill. And keep your app's storage code thin and S3-shaped, so moving later means changing an endpoint and some keys rather than rewriting.
One more thing: object storage isn't the same as Drive-style file sharing for staff. If that's what you need, look at cloud storage for business instead, and if you hold patient data, start with HIPAA-compliant cloud storage.
A two-file test migration plan
- Pick two real files: one small file your app reads constantly, and one large file you rarely touch.
- Create a trial bucket with the provider and copy both files using the exact tool you use today.
- Read the small file from your app many times and the large file once, then check the usage page for what was counted.
- Turn on each feature you rely on, such as versioning or lifecycle rules, and confirm it behaves as your app expects.
- Delete both files and check they've gone, including any old versions.
- Only then plan the full move, using the usage page from your test as the guide.

Frequently asked questions
What is object storage?
Object storage keeps files as objects in buckets, reached over an API rather than a shared drive. It's widely used for backups, media, app uploads and data lakes.
What does S3-compatible mean?
It means a provider supports the same basic API as the original S3 service, so many tools and libraries work with it. Advanced features can still differ, so test the ones you use.
Why do egress charges matter so much?
Egress is data leaving the bucket. For apps that serve lots of files, those charges can grow faster than storage, so they often decide the bill.
Can I try object storage for free?
Several providers offer a free start, a free tier or a free trial as of Nov 2026. Check the terms for limits before you rely on them.
Is self-hosted object storage a good idea for a small team?
Only if someone on the team is happy to run servers, replace disks and handle upgrades. Otherwise a managed provider is less work.
Do I need a CDN with object storage?
If you serve files to lots of visitors, a CDN in front of the bucket speeds things up and cuts reads from storage. Some providers include one; others don't.
