If you work with cloud storage at a professional level, you’ve probably dealt with the hassle of juggling multiple dashboards, clients, and credentials, one for AWS, another for Wasabi, yet another for Backblaze. Air Explorer puts an end to that fragmentation by letting you connect and manage all your S3-compatible cloud services from a single, familiar interface that works just like Windows Explorer.

Here are 7 S3-compatible cloud storage services you can connect to Air Explorer today, and why each one is worth considering.

What Does “S3-Compatible” Mean?

Amazon S3 (Simple Storage Service) set the standard for object storage APIs. Any service described as “S3-compatible” speaks the same protocol, meaning tools built for S3 (like Air Explorer) can connect to them without any extra configuration or plugins. This gives you massive flexibility: you can mix and match providers based on price, location, or performance, all while using a single management tool.

1. Amazon S3 (AWS)

The original and most widely used object storage service in the world. AWS S3 is the backbone of thousands of applications, data pipelines, and enterprise backup strategies. With Air Explorer, you can browse your S3 buckets, transfer files between regions or to other clouds, and set up automated sync tasks, all without writing a single line of CLI code. If you already use AWS, connecting it to Air Explorer takes less than two minutes using your access key and secret key.

2. Wasabi

Wasabi has become one of the most popular AWS S3 alternatives for businesses looking to cut storage costs. It offers comparable speeds with no egress fees and a pricing model that is significantly cheaper than AWS for high-volume storage. Air Explorer connects to Wasabi natively, making it an excellent choice if you want to migrate data from AWS S3 to a more budget-friendly option, or simply manage both in parallel from the same window.

3. Backblaze B2

Backblaze B2 is a favorite among developers and small-to-medium businesses for its transparent pricing and reliability. Its S3-compatible API (introduced in 2020) means Air Explorer can connect to it just like any standard S3 bucket. Backblaze B2 is particularly strong for backup workloads: pair it with Air Explorer’s built-in scheduler and you get fully automated, unattended backups running on your own timetable.

4. IDrive e2

IDrive e2 is a newer player in the S3-compatible storage space, but it has quickly gained traction thanks to its extremely competitive pricing, often significantly cheaper than both AWS and Wasabi for high-capacity use cases. It supports multiple storage regions across the US, Europe, and Asia. With Air Explorer, you can connect your IDrive e2 buckets alongside your other clouds and move data between them in a single drag-and-drop operation.

5. Azure Blob Storage

Microsoft Azure Blob Storage is not natively S3, but Air Explorer supports it directly through its own connector, making it part of your unified cloud workspace. Azure Blob is the go-to choice for teams already inside the Microsoft ecosystem, especially those using Azure Active Directory, Microsoft 365, or SharePoint. Managing Azure Blob alongside your S3 buckets from the same Air Explorer window is a genuine productivity boost for hybrid infrastructure teams.

6. Alibaba Cloud OSS

Alibaba Cloud Object Storage Service (OSS) is the dominant cloud storage platform in Asia and a strategic choice for businesses operating in or serving Chinese and Southeast Asian markets. It is fully S3-compatible, and Air Explorer connects to it using standard S3 credentials. If your workflow involves transferring data between a Western cloud provider (like AWS or Wasabi) and Alibaba Cloud, Air Explorer makes that cross-region, cross-provider transfer seamless.

7. Orange Flexible Engine OBS

Less well known in the English-speaking world, Orange Flexible Engine is a European cloud platform built on OpenStack and offered by the French telecom giant Orange. Its Object Block Storage (OBS) is S3-compatible and appeals to organizations with strict European data residency requirements, particularly relevant under GDPR. Air Explorer’s support for Orange Flexible Engine makes it one of the few desktop tools that covers this provider, giving European businesses a compliant and centrally managed storage option.

Why Manage All of Them from Air Explorer?

The real power is not in connecting one S3 provider, it’s in connecting all of them at once. Air Explorer lets you:

• Transfer files directly between clouds without downloading to your local disk first (processed in RAM, on-the-fly)
• Set up mirror or bidirectional sync between any two S3-compatible buckets
• Schedule automated backup tasks on Windows and Mac, running unattended in the background
• Manage multiple accounts from the same provider simultaneously
• Search across all connected clouds from a single interface

Whether you are a sysadmin managing multi-region backups, a developer moving data between environments, or a business looking to reduce cloud vendor lock-in, Air Explorer gives you a centralized, visual control panel for your entire S3-compatible infrastructure.

Ready to centralize your entire S3 infrastructure in one place? Download Air Explorer and connect your first S3-compatible service in minutes, whether you prefer a visual interface, scheduled automation, or command-line control.
