Cloudflare Tunnel Price Breakdown & Cost Analysis: A Deep Dive

Cloudflare Tunnel (formerly known as Argo Tunnel) is a powerful tool for securely connecting your origin servers to the Cloudflare network without opening inbound ports on your firewall. This significantly enhances security by eliminating a major attack vector and improves performance by leveraging Cloudflare’s global network. However, understanding the pricing structure can be complex, as it’s based on a combination of factors, not just a simple flat fee. This article provides a detailed breakdown of Cloudflare Tunnel’s pricing, various cost considerations, and practical examples to help you estimate and optimize your spending.

I. The Core Components of Cloudflare Tunnel Pricing

Cloudflare Tunnel’s pricing isn’t a one-size-fits-all model. It’s primarily driven by the following components:

Zero Trust Subscription (Essential Component):
- Free Tier: Cloudflare offers a generous Free tier for Zero Trust, which includes access to Cloudflare Tunnel for up to 50 users. This is an excellent starting point for small teams, personal projects, or testing purposes. The free tier includes 1 Tunnel, which may suit the needs of many small deployments.
- Standard Tier: This is the entry-level paid tier, priced per user per month. The current pricing (as of October 26, 2023) is typically around $7/user/month, but it’s crucial to check Cloudflare’s official pricing page for the most up-to-date information. This tier unlocks more features within the Zero Trust platform, including more comprehensive access policies, device posture checks, and advanced reporting. It also allows for more Tunnels to be created.
- Enterprise Tier: For larger organizations with complex security and networking needs, the Enterprise tier offers custom pricing and features. This tier typically includes dedicated support, service level agreements (SLAs), and advanced security features like custom key management and integrations with third-party security information and event management (SIEM) systems. Pricing is negotiated based on the organization’s specific requirements.
Key Takeaway: You must have a Zero Trust subscription (even the Free tier) to use Cloudflare Tunnel. The Standard and Enterprise tiers are priced per user.
Tunnel Data Transfer (Usage-Based):
- Within Zero Trust Bundle: The good news is that if your traffic is being routed through Cloudflare Tunnel as part of your Zero Trust setup (e.g., for Zero Trust Network Access (ZTNA)), the data transfer through the tunnel is typically included within your Zero Trust subscription, up to a certain limit, often far exceeding typical usage for ZTNA. You are not charged extra per gigabyte for this type of traffic. This is a significant advantage, as it simplifies cost prediction.
- “Naked” Tunnel Usage (Separate from Zero Trust Bundle): This is where pricing can become more complex. If you’re using Cloudflare Tunnel solely to connect your origin server to Cloudflare (for example, to serve public web traffic through Cloudflare’s CDN without using the ZTNA features), then you’ll be charged based on data transfer. This scenario is less common, as most users leverage Tunnel within the broader Zero Trust framework.
  - First Gigabyte Free: Cloudflare provides the first gigabyte of data transfer through a “naked” tunnel for free each month.
  - Beyond the First Gigabyte: After the first free gigabyte, you’re charged a per-gigabyte rate. The current rate (as of October 26, 2023) is typically around $0.10/GB, but always check the official pricing page for the latest information. This rate can vary based on region and negotiated contracts (especially for Enterprise customers).
Key Takeaway: Data transfer within a Zero Trust deployment (for ZTNA) is generally included in your Zero Trust subscription. Data transfer for “naked” tunnels (used solely for connecting to Cloudflare, without ZTNA) is charged per gigabyte after the first free gigabyte.
Cloudflare Workers (Optional, but Potentially Relevant):
- Cloudflare Tunnel can be integrated with Cloudflare Workers, serverless functions that run on Cloudflare’s edge network. Workers can be used to perform a variety of tasks, such as modifying HTTP requests and responses, implementing custom routing logic, and performing data transformations.
- Workers Pricing: Workers have their own separate pricing structure, based on the number of requests and the amount of CPU time used. The Free tier includes a generous number of requests and CPU time, making it suitable for many use cases. Paid plans offer higher limits and additional features.
- Relevance to Tunnel: While not directly part of Tunnel’s pricing, if you use Workers in conjunction with Tunnel (e.g., to process traffic before it reaches your origin server), you’ll need to factor in the Workers cost.
Key Takeaway: If you use Cloudflare Workers with your Tunnel setup, you’ll need to consider the Workers pricing separately.
Number of Tunnels:
- Free Tier: Provides a single tunnel.
- Standard Tier: Provides the ability to create multiple tunnels.
- Enterprise Tier: Provides even higher or negotiated limits on the number of tunnels.
While there isn’t a direct per-tunnel cost beyond the Zero Trust subscription, the number of tunnels you can create is tied to your subscription tier. If you need to connect multiple servers or services in different locations, you’ll need to ensure your chosen tier supports the required number of tunnels.

Key Takeaway: The number of tunnels allowed is dependent on the subscription tier, not an extra line-item cost.

II. Cost Analysis Scenarios and Examples

To illustrate the pricing breakdown, let’s consider several common scenarios:

Scenario 1: Small Team Using ZTNA (Zero Trust Network Access)

Tunnel Usage: Primarily for ZTNA; data transfer is within the Zero Trust bundle.
Number of Tunnels: 1
Workers: Not used.
Cost Calculation:
- Zero Trust Subscription: 10 users * $7/user/month = $70/month
- Tunnel Data Transfer: Included in Zero Trust subscription.
- Workers: $0
Total Estimated Cost: $70/month

Scenario 2: Medium-Sized Business with Multiple Applications

Team Size: 50 users
Use Case: Securely accessing multiple internal applications hosted on different servers, some requiring different access policies.
Zero Trust Tier: Standard ($7/user/month)
Tunnel Usage: Primarily for ZTNA; data transfer is within the Zero Trust bundle.
Number of Tunnels: 3 (one for each server group)
Workers: Used for basic request logging (falls within the Workers Free tier).
Cost Calculation:
- Zero Trust Subscription: 50 users * $7/user/month = $350/month
- Tunnel Data Transfer: Included in Zero Trust subscription.
- Workers: $0 (Free tier)
Total Estimated Cost: $350/month

Scenario 3: Large Enterprise with Complex Needs

Team Size: 1000+ users
Use Case: Securely accessing a wide range of internal and external applications, with strict compliance requirements and advanced security needs.
Zero Trust Tier: Enterprise (custom pricing)
Tunnel Usage: Primarily for ZTNA; data transfer is within the Zero Trust bundle. May also have some “naked” tunnel usage for specific high-traffic applications.
Number of Tunnels: 10+
Workers: Extensive use of Workers for custom authentication, authorization, and data processing (likely requires a paid Workers plan).
Cost Calculation:
- Zero Trust Subscription: Negotiated Enterprise pricing (e.g., $5/user/month) = $5000+/month
- Tunnel Data Transfer: Mostly included in Zero Trust. “Naked” tunnel usage: 100 GB/month * $0.10/GB = $10/month (after the first free GB)
- Workers: Paid Workers plan (e.g., $50/month)
Total Estimated Cost: $5060+/month (This is a highly simplified example; Enterprise pricing is highly variable.)

Scenario 4: Website Hosting with “Naked” Tunnel (Less Common)

Team Size: 1 user (for management)
Use Case: Hosting a public website on a server, using Cloudflare Tunnel to connect to Cloudflare’s CDN without using ZTNA features.
Zero Trust Tier: Free
Tunnel Usage: “Naked” tunnel; all traffic is charged per GB.
Number of Tunnels: 1
Workers: Not Used
Cost Calculation:
- Zero Trust Subscription: $0 (Free tier)
- Tunnel Data Transfer: Let’s assume 500 GB of website traffic per month. 500 GB – 1 GB (free) = 499 GB. 499 GB * $0.10/GB = $49.90/month
- Workers: $0
Total Estimated Cost: $49.90/month (This scenario highlights the importance of using Tunnel within a Zero Trust context for cost savings.)

Scenario 5: Using Workers to Preprocess Requests

Team Size: 20 Users

Zero Trust Tier: Standard ($7/user/month)
Tunnel Usage: Primarily for ZTNA
Number of Tunnels: 2
Workers: Paid Tier (e.g., $5/month for additional requests/CPU time)
Cost Calculation:
- Zero Trust Subscription: 20 users * $7/user/month = $140/month
- Tunnel Data Transfer: Included in Zero Trust
- Workers: $5/month
Total Estimated Cost: $145/month

III. Cost Optimization Strategies

Once you understand the pricing components, you can implement strategies to optimize your Cloudflare Tunnel costs:

Leverage Zero Trust: The most significant cost-saving strategy is to use Cloudflare Tunnel within the context of a Zero Trust deployment. This way, your data transfer is typically included in your Zero Trust subscription, avoiding per-gigabyte charges.
Optimize Worker Usage: If you use Cloudflare Workers, carefully monitor your request and CPU time usage. Optimize your Worker code to minimize resource consumption. Consider using the Workers Free tier if your usage falls within its limits.
Monitor Data Transfer: Regularly monitor your data transfer through Cloudflare Tunnel, especially if you have any “naked” tunnel usage. Identify any unexpected spikes in traffic and investigate their cause. You can use Cloudflare’s analytics dashboard to track data transfer.
Right-Size Your Zero Trust Tier: Choose the Zero Trust tier that best fits your needs. The Free tier is a great starting point, but if you need more features or have a larger team, the Standard tier is a cost-effective option. For large organizations, the Enterprise tier offers custom pricing and features.
Cache Content: If you’re using Cloudflare Tunnel to serve public web traffic, leverage Cloudflare’s CDN to cache static content. This reduces the amount of data that needs to be transferred from your origin server, lowering your “naked” tunnel costs.
Compress Data: Enable compression (e.g., gzip or Brotli) on your origin server to reduce the size of data transferred through the tunnel.
Consolidate Tunnels: If possible, consolidate multiple tunnels into fewer tunnels. While there isn’t a direct per-tunnel cost, reducing the number of tunnels can simplify management and potentially reduce the complexity of your configuration. Each tunnel creates overhead in terms of configuration and maintenance, so minimizing the number of tunnels is generally a good practice.
Use Cloudflare’s Other Services: Cloudflare offers a comprehensive suite of security and performance services. Consider using services like Web Application Firewall (WAF), DDoS protection, and Load Balancing in conjunction with Cloudflare Tunnel to further enhance your security posture and optimize performance. This can indirectly reduce costs by preventing attacks and improving efficiency.
Regularly Review Your Usage: Cloudflare’s billing dashboard provides detailed information about your usage and costs. Regularly review this information to identify any areas where you can optimize your spending.
Consider Annual Billing: Cloudflare often offers discounts for annual billing compared to monthly billing. If you’re committed to using Cloudflare Tunnel for the long term, consider paying annually to save money.

IV. Comparing Cloudflare Tunnel to Alternatives

While Cloudflare Tunnel offers a compelling solution, it’s essential to consider alternatives:

Traditional VPNs: Virtual Private Networks (VPNs) are a common way to securely connect to remote networks. However, traditional VPNs can be complex to manage, often require opening inbound ports on your firewall, and can introduce performance bottlenecks. Cloudflare Tunnel offers a more secure and performant alternative by eliminating the need for inbound ports and leveraging Cloudflare’s global network.
Reverse Proxies (e.g., Nginx, HAProxy): You could set up your own reverse proxy server to handle inbound connections and forward them to your origin server. This approach gives you more control but requires significant technical expertise to configure and maintain securely. Cloudflare Tunnel simplifies this process and provides additional security benefits.
Other Zero Trust Network Access (ZTNA) Solutions: Several other vendors offer ZTNA solutions, such as Zscaler, Netskope, and Perimeter 81. These solutions often have different pricing models and feature sets. It’s important to compare these solutions based on your specific requirements and budget.
SSH Tunneling: SSH tunneling can be used to create a secure connection between your local machine and a remote server. However, SSH tunneling is typically used for individual connections, not for exposing services to the internet or providing secure access to multiple users.
