Cloudflare R2
Global object storage with zero egress fees
Powered by our programmable global network, R2 enables you to create flexible, multicloud architectures with S3-compatible object storage.
Benefits of Cloudflare R2
S3-compatible object storage
Our S3-compatible API gives you added flexibility — allowing you to access a wide range of S3 tools, libraries, and extensions.
No egress charges
Our affordable, consistent pricing helps free up resources across your organization — and you never have to pay egress fees for data accessed from R2.
Easy migration from existing providers
Our automated migration service helps migrate your objects all at once or over time — whatever aligns with your current needs.
HOW IT WORKS
Avoid vendor lock-in with our global object storage
Cloudflare R2 allows you to store large amounts of unstructured data — without the costly egress fees or vendor lock-in associated with other cloud storage providers.
R2 natively integrates with Cloudflare Workers, so you can easily perform authentication, route requests, and deploy edge functions across our network of 330+ data centers.
Reduce cloud spend and avoid hidden costs
What our customers are saying
"No egress fees is a big advantage, as surprise costs from surging traffic can be annoying... one has to be careful about surging costs for DDoS or viral traffic, but with Cloudflare, these worries are eliminated. Thanks to Cloudflare, startups don’t need to scale up dramatically or set up their own servers. This results in significant cost savings and eliminates the need for our own infrastructure."
