Near-infinite scale

Access data from anywhere, create millions of buckets, and write as much data as you need to run your business.

Sleep better

Don't wake up to a huge egress bill overnight: R2 doesn't charge for egress.

S3-compatible APIs

R2 exposes S3 compatible APIs: use your existing tools without a rewrite.

Progressive migration

R2 can sit in front of your legacy object storage provider and progressively copy objects as they are requested, taking the complexity of managing data migration.

R2 Data Catalog

Use R2's Iceberg-compatible data catalog with your favorite SQL data warehouse to query logs and structured data formats you store in R2.

Part of Cloudflare Workers

Access your R2 buckets directly from your Workers code without having to juggle API keys and SDKs with a native Workers API.

Store anything, serve everywhere

R2 is globally distributed object storage designed for modern applications. Durable, S3-compatible, and tightly integrated with Workers for building data-driven systems without extra infrastructure.

Store application data without egregious egress fees

Download your data from R2 without worrying that your egress bill is scaling 1:1 with your growth. Store and access user content, AI training data, logs and columnar data without breaking the bank.

Store AI datasets and model artifacts

Keep training data, model weights, and analytics datasets accessible from any cloud provider without transfer fees. Data portability enables better infrastructure choices.

Break free from cloud vendor lock-in

Store your data neutrally and access it from any cloud provider for compute workloads. Choose the best tools without being trapped by transfer costs.

Migration without the risk

Configure R2 to pull objects from your existing object storage provider as they are requested, allowing you to switch to R2 without having to manage large-scale data migration and benefit from zero-egress fees immediately.

Drop-in replacement for existing S3 workflows

Switch your endpoints to R2 and keep using your current tools, SDKs, and pipelines. R2's S3-compatible API makes migration frictionless.

import boto3

s3 = boto3.resource('s3',
  endpoint_url = 'https://{your-account-id}.r2.cloudflarestorage.com',
  aws_access_key_id = '{access_key_id}',
  aws_secret_access_key = '{access_key_secret}'
)
