Editorial verdict

Cloudflare 已是主要平台、需要文件存储与边缘交付组合的团队可优先比较。³ ⁴ ⁵

Best for

Cloudflare-centered applications serving stored objects through the same network
Workloads where direct object-delivery transfer charges dominate storage-provider selection
Teams using a verified subset of S3-compatible clients and operations

³ ⁴ ⁵

不适合

Systems that require unverified S3 features, integrations, or exact behavior
Workloads whose primary requirement is deep AWS-native service integration
Products expecting object storage alone to solve upload authorization and application callbacks

³ ⁴ ⁵

Main trade-off

平台整合很顺畅，但会加深对象数据和应用运行面的集中度。³ ⁴ ⁵

产品边界

当对象交付、边缘函数和成本边界都已围绕 Cloudflare 设计时进行评估。

R2 is object storage. Its S3-compatible API is a documented compatibility layer, not a claim of complete S3 service or behavioral parity, and it is not a finished end-user upload workflow.³ ⁴

适用范围： Teams delivering objects through Cloudflare or seeking an S3-compatible object store with a different egress shape

A required client operation or integration is absent from R2's compatibility matrix.
The delivery architecture is already committed to Cloudflare Workers and Cloudflare caching.
Data residency, jurisdiction, or support terms require a provider-specific review.

为什么团队会评估 Cloudflare R2

Cloudflare delivery fitR2 is designed to connect with Cloudflare's network and developer platform.³ ⁴
S3-compatible accessA documented S3 API subset supports familiar clients when the required operations are compatible.³ ⁴
Distinct transfer modelThe public pricing model separates storage and operations and documents no direct R2 egress charge.³ ⁴

价格与计费

R2 publishes storage, Class A and Class B operation, retrieval, and related service dimensions. The no-direct-egress statement does not eliminate every possible network, transformation, request, or adjacent Cloudflare charge.⁵

Workload estimate

Usage based

Estimate storage class, operation classes, retrieval, and any adjacent delivery or processing services.⁵

Primary meters: Storage, operations, and retrieval dimensions⁵
Compatibility gate: Required S3 operations must be checked against the published compatibility page⁵

Cloudflare R2 与替代方案

Amazon S3

Choose when: Choose S3 when AWS-native integration, regional options, and storage-control breadth are more important.
Compared with Cloudflare R2: The pricing and policy surface is more complex.¹ ²

Supabase Storage

Choose when: Choose it when storage authorization should share Supabase Auth and Postgres RLS context.
Compared with Cloudflare R2: The solution is more tightly coupled to the Supabase project.⁶ ⁷

Backblaze B2

Choose when: Choose B2 for a cost-focused S3-compatible object store without making Cloudflare the application platform.
Compared with Cloudflare R2: Its native platform and regional breadth are narrower than hyperscalers.⁹ ¹⁰
