Key features

Everything you need to build scalable, secure, and cost-effective storage into your applications.

S3-Compatible API

Fully compatible with the AWS S3 API. Works with existing AWS SDKs (Python boto3, Node.js, Go, PHP), tools like the AWS CLI, s3cmd, rclone, and any S3-aware application without code changes.

11x9s Durability

Data is synchronously replicated across 3 availability zones within your chosen region. 99.999999999% durability means losing one object in a billion takes over 10,000 years on average.

Global CDN Integration

One toggle in the dashboard enables CDN distribution. Assets are cached at edge locations across 12 regions, reducing latency for end users worldwide and eliminating egress costs for cached hits.

Lifecycle Policies

Automate object management at scale. Define rules to automatically expire old objects, transition to lower-cost Infrequent Access or Archive tiers, or auto-delete after a set number of days.

Versioning

Enable per-bucket versioning to keep the full history of every object. Restore any previous version with a single API call. Combined with lifecycle policies, limit retained versions to control storage costs.

Signed URLs

Generate time-limited, pre-signed URLs to grant temporary read or write access to private objects — without exposing your credentials or making the bucket public. Expiry from 1 second to 7 days.

Technical specifications

Everything you need to integrate and architect reliably.

API quick start

Use the AWS CLI pointed at our S3-compatible endpoint. No code changes needed.

# Install AWS CLI (uses S3-compatible endpoint)
$ pip install awscli
# Configure credentials
$ aws configure set aws_access_key_id YOUR_ACCESS_KEY
$ aws configure set aws_secret_access_key YOUR_SECRET_KEY
$ aws configure set default.region nyc
# Create bucket
$ aws s3 mb s3://my-bucket --endpoint-url https://s3.host.com
# Upload file
$ aws s3 cp ./file.txt s3://my-bucket/file.txt --endpoint-url https://s3.host.com
# List objects
$ aws s3 ls s3://my-bucket --endpoint-url https://s3.host.com
# Generate signed URL (expires in 1 hour)
$ aws s3 presign s3://my-bucket/file.txt --expires-in 3600 --endpoint-url https://s3.host.com
