Cloudflare R2
FreemiumS3-compatible object storage with zero egress fees, automatic migration from S3, and integration with Cloudflare Workers for edge computing.
What does this tool do?
Cloudflare R2 is an S3-compatible object storage service designed as a direct alternative to Amazon S3, with the primary differentiator being zero egress fees—meaning you don't pay for data transfer out of the service. It integrates deeply with Cloudflare's edge network and Workers platform, allowing developers to process and serve files from edge locations globally. The S3 compatibility means existing S3 clients, SDKs, and workflows can migrate with minimal code changes. R2 also offers automatic migration tooling from S3, reducing friction for switching providers. While the website content is limited on specific technical details, the service positions itself as a cost-effective storage layer for bandwidth-heavy applications and workloads where egress costs typically dominate total infrastructure spending.

- 6CDN-adjacent storage for web assets that need edge processing with Workers
Pros & Cons
Advantages
- Zero egress fees eliminate a major cost variable for data-heavy applications, making total cost of ownership predictable
- S3 API compatibility allows near-drop-in replacement for existing S3 workflows without significant refactoring
- Native integration with Cloudflare Workers enables serverless compute at the edge with direct access to stored objects
- Automatic S3 migration tooling reduces switching friction and operational overhead
Limitations
- Pricing details are absent from the public website, making cost comparison with competitors difficult for storage and API requests
- Limited information on geographic region availability, redundancy options, or SLA commitments
- Dependent on Cloudflare's existing global infrastructure; less mature than AWS S3 with potentially fewer feature parity areas
- No visibility into performance benchmarks, compliance certifications (SOC2, HIPAA, etc.), or customer case studies from the provided content
Pricing Details
Pricing details not publicly available. The website does not display pricing tiers, storage costs, API request fees, or comparison tables.
Who is this for?
Developer teams and engineering-focused companies building content distribution platforms, media applications, or serverless architectures on Cloudflare. Best suited for organizations with significant data egress requirements where AWS S3 egress costs are a pain point, or those already invested in Cloudflare's ecosystem (Workers, Pages, CDN). Mid-market SaaS companies and startups prioritizing cost efficiency over feature maturity.
