Scalable, durable, affordable object storage

Build stateful applications that read and write data globally, integrate directly with Workers, and scale without infrastructure overhead or surprise storage costs.

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 out 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.

R2 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.

Migration without the risk

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}')export default { async fetch(request, env) { let key = new URL(request.url).searchParams.get('key'); // Write an object to R2 directly await env.MY_BUCKET.put(key, request.body);

// Fetch an object (or objects!) using the Workers API: const object = await env.MY_BUCKET.get(key); return new Response(object); },};-- Install the iceberg DuckDB extension and load the extension.INSTALL iceberg;LOAD iceberg;

-- Create a DuckDB secret to store Basin Catalog credentials.CREATE SECRET r2_secret ( TYPE ICEBERG, TOKEN '');

-- Attach your Basin CatalogATTACH '' AS prod_analytics_data ( TYPE ICEBERG, ENDPOINT '');

-- Show all available tables.SHOW ALL TABLES;

-- Query your Iceberg table.SELECT * FROM prod_analytics_data.default.user_events;
