S3-Compatible Storage on a Peer-to-Peer Network

Use your existing S3 tools with your self-hosted gateway. Same API, your endpoint. Encrypted by default.

Start Storing →
Upload file

Any file, any size. Encrypted before it leaves your device.

Content hash

A unique fingerprint derived from your file's contents.

Content address

A permanent link. Valid as long as your content is pinned.

Change Your Endpoint, Keep Your Tools

Existing S3 tools work immediately. AWS CLI, boto3, rclone, Terraform. Point them at your gateway instead of AWS. Same API, your endpoint.

Hosts prove storage. Or they don't get paid.

Encrypted by Default

You deploy your own gateway appliance. It handles encryption locally and stores only encrypted fragments on the Sia network. You control the keys, the software, and the data. Minimal CPU requirements, runs on any VPS.

No surprise bills

Simple per-TB pricing. No per-request fees. Priced upfront. See our pricing page for details.

What you can store

Use the S3 tools you already have, on a network you control.

Backups & Disaster Recovery

Automated backups to S3-compatible storage on a peer-to-peer network. Use rclone, restic, or any S3 backup tool you already run. Encrypted by default, no surprise bills.

Start Storing

Private AI & RAG Pipelines

Store embeddings, vector databases, and knowledge bases through your own gateway. Your data is encrypted locally before it leaves your server. You control the keys.

Start Storing

Agency Client Files

Keep sensitive client documents on storage you control. Deploy your own gateway, use your existing S3 tools, and maintain custody of your encryption keys.

Frequently Asked Questions

Deploy the gateway appliance on your server, then change your endpoint URL and credentials to point at it. That's it. AWS CLI, boto3, rclone, Terraform, and any S3-compatible tool will work. Your buckets, objects, and access patterns stay the same.

We support the core S3 operations: CreateBucket, ListBuckets, PutObject, GetObject, DeleteObject, ListObjects, and multipart uploads. The S3 implementation is part of the Sia network's open-source software. If you need an operation that isn't supported yet, let us know and we'll pass the feedback to the team.

Your gateway appliance encrypts files locally before anything leaves your server. The encryption key lives on your machine. Not in our database, not on the Sia storage hosts. They only see encrypted fragments.

Any tool that speaks the S3 API works: AWS CLI, boto3, rclone, s3cmd, Cyberduck, Terraform's AWS provider, MinIO client, and language SDKs for Go, Python, JavaScript, Java, and more. Just point them at your gateway's endpoint.

Yes. You deploy your own gateway appliance that handles encryption locally. A simpler 1-click setup is in development. Subscribe to get notified when it's ready.
