Your bucket

Any storage that speaks S3.

Set an endpoint and s3nd adjusts the two defaults S3-compatible providers expect. Both stay overridable. The CLI writes a starter configuration for each provider, and doctor tells you whether it actually works.

Providers in the docs

const store = createBucket({
  bucket: 'transfers',
  endpoint: 'https://…',   // set this, and two defaults follow:
  // region: 'auto'        // for providers that ignore the region
  // forcePathStyle: true  // https://endpoint/bucket/key
})

Providers

Pick yours.

s3nd init --provider r2

Cloudflare R2

No egress fees, which is exactly what moving a 2 GB file between two laptops wants.

s3nd init --provider aws

AWS S3

The original. Credentials come from the provider chain, so a Lambda or an ECS task needs no keys at all.

s3nd init --provider minio

MinIO

One Docker command, and the real code path runs on your laptop and in CI.

s3nd init --provider scaleway

Scaleway Object Storage

European regions, S3-compatible, and the region actually means something.

s3nd init --provider wasabi

Wasabi

Flat-rate storage with no egress charge, on a regional endpoint.

Not listed? Ceph, Garage, SeaweedFS, Backblaze B2, DigitalOcean Spaces and the rest work the same way: an endpoint, a key pair, and s3nd doctor to confirm the conditional writes are honoured. The CLI has the details.

Put a file. Hand over the code.

Point it at the bucket you already pay for. Nothing to deploy, nothing to sign up for, nothing in the middle.
