How Cloudflare R2 Makes My Life Easy
Every developer dreams of an effortless, cost-effective way to store files on a server that can be accessed anywhere using an endpoint (URL). I’ve been on this journey since I started coding, searching for a solution to store files like resumes, pictures, or project resources. This struggle is shared by students working on college projects or hobbyists who need reliable yet free storage options.
In this article, we’ll dive deep into Cloudflare R2, a service designed to solve these challenges. We’ll cover what Cloudflare R2 is, how to use it, whether it’s free, its limitations, and even how to integrate it into your code.
What is Cloudflare R2?
Cloudflare R2 is an object storage service that enables developers to store large amounts of unstructured data, such as:
- Images
- Videos
- PDF files
- Static HTML and JavaScript files
The key advantage of R2 is its simplicity and affordability. It’s built on the principles of AWS S3, but with a twist — it eliminates data egress fees, making it a cost-effective choice for developers.
For an official overview, you can refer to Cloudflare’s R2 Documentation.
How Does Cloudflare R2 Compare to AWS S3?
AWS S3 is Amazon’s storage solution, where you can upload and download files via APIs and endpoints. While S3 is powerful, its costs, especially data egress fees, can be prohibitive for small-scale developers.
Cloudflare R2 leverages S3’s backend infrastructure but removes the data egress costs, allowing you to store and access files affordably.
Is Cloudflare R2 Free?
The short answer is yes and no. Here’s why:
Free Tier: Cloudflare R2 provides a generous free tier:
- 10 GB of storage per month
- 1 million Class A operations (e.g., PUT, POST, LIST requests) per month
- 10 million Class B operations (e.g., GET, HEAD requests) per month
Beyond Free Tier: Costs apply if you exceed these limits. To understand the pricing better, visit the official Cloudflare R2 Pricing page.
What Are Class A and Class B Operations?
Class A operations involve creating or modifying files, while Class B operations relate to accessing files. For a detailed breakdown, refer to Cloudflare’s documentation.
How Does Cloudflare R2 Compare to AWS S3 Pricing?
To compare costs, use the R2 Calculator. Enter your storage and request requirements, and it will calculate the costs for both R2 and S3.
Why Choose Cloudflare R2 Over AWS S3?
While AWS S3 charges for both storage and data transfer, Cloudflare R2 provides a free tier with no egress fees. Surprisingly, R2 leverages S3 infrastructure, allowing you to enjoy the benefits of S3 without directly incurring its cost
Getting Started with Cloudflare R2
Creating a Cloudflare account is straightforward:
- No credit card or debit card required.

How to Integrate Cloudflare R2 with Node.js
If you’re a developer looking to integrate Cloudflare R2 with your application, I’ve written a detailed guide on setting it up with Node.js. The guide includes code snippets and a link to my GitHub repository. You can find it here.
Limitations of Cloudflare R2
While R2 offers many advantages, it’s essential to consider the following limitations:
- Free Tier Restrictions: Limited to 10 GB of storage and specific API request quotas.
- Learning Curve: Familiarity with API integrations and object storage concepts is required.
- Compatibility: Though based on S3, some advanced S3 features may not be fully supported.
Conclusion
Cloudflare R2 simplifies file storage for developers, offering a cost-effective, flexible, and developer-friendly alternative to AWS S3. With its free tier, absence of egress fees, and easy integration, R2 is a compelling option for students, hobbyists, and professionals alike.
