All eight providers support listing, browsing, direct single-part upload, preview, download, delete, and CORS inspection and update, wherever the stored provider credential permits.

| Provider | API and endpoint input | Multipart | Create storage in quickS3 | Creation permission or limitation |
| --- | --- | :---: | :---: | --- |
| [AWS S3](/docs/connections/aws-s3/) | S3; region and endpoint | Yes | Yes | `s3:CreateBucket` |
| [Azure Blob Storage](/docs/connections/azure-blob/) | Azure Blob; endpoint from account name | No | Container | Storage account key with container write access |
| [Backblaze B2](/docs/connections/backblaze-b2/) | S3-compatible; paste regional endpoint | Yes | Yes | Application key with `writeBuckets` |
| [Cloudflare R2](/docs/connections/cloudflare-r2/) | S3-compatible; endpoint from account ID and jurisdiction | Yes | Yes | R2 Admin Read & Write token |
| [DigitalOcean Spaces](/docs/connections/digitalocean-spaces/) | S3-compatible; endpoint from region | Yes | Yes | Key with access to all Spaces, not a per-Space limited key |
| [Google Cloud Storage](/docs/connections/google-cloud-storage/) | XML/S3 interoperability; endpoint and HMAC keys | Yes | No | Create in Google Cloud, then refresh |
| [MinIO](/docs/connections/minio/) | S3-compatible; paste reachable HTTPS endpoint | Yes | Yes | Provider-equivalent create permission |
| [Wasabi](/docs/connections/wasabi/) | S3-compatible; endpoint from region | Yes | Yes | Provider-equivalent create permission |

"Yes" for multipart means the browser implementation is verified for that provider and engages automatically at 256 MiB. It never overrides the connection's configured cap or the provider's own object-size, part, quota, and rate limits.

## Choosing between similar providers

Decide on the things quickS3 does not change: where the data must live, provider account controls, egress and request pricing, recovery features, and whether the browser can reach the endpoint at all. quickS3 makes the file workflow identical; it does not make durability, versioning, retention, or billing equivalent.

For private or self-hosted MinIO, remember the endpoint must be reachable by quickS3's Cloudflare Worker for metadata and signing. A hostname that only resolves on your laptop will not work in hosted quickS3.
