Cloudflare vs Bunny.net vs Fastly: CDN Features and Pricing Compared

Overview

For most teams, a CDN comparison becomes confusing for one simple reason: vendors package similar outcomes in very different ways. One platform may feel broader and easier to adopt for general website speed optimization. Another may be attractive because the pricing model is simple and the setup is light. A third may stand out when fine-grained edge logic, advanced purge workflows, or developer-centric delivery controls matter more than convenience.

That is why a useful buyer guide should compare categories, not slogans. When you evaluate Cloudflare vs Bunny.net vs Fastly, focus on six areas:

• Core delivery model: Is the vendor mainly serving as an origin pull CDN, a reverse proxy cache, or a broader edge platform with security, routing, and application features?
• Cache behavior: How much control do you have over cache-control headers, edge caching policies, stale handling, bypass rules, and cache variation?
• Purge and invalidation: Can you purge by URL, prefix, tag, host, or key? How important is instant cache purge to your publishing flow?
• Operational visibility: How easy is it to inspect headers, diagnose cache misses, monitor cache hit ratio, and explain TTFB changes to stakeholders?
• Developer workflow: Do you need edge rules, configuration as code, API-first control, log streaming, or programmable behavior at the edge?
• Pricing shape: Are costs driven mostly by bandwidth, requests, feature tiers, image optimization, WAF or security add-ons, log delivery, or support level?

At a high level, buyers often view the three options like this:

• Cloudflare: Commonly considered when teams want a broad edge platform, strong DNS and proxy integration, website caching controls, and a large bundle of performance and security features in one place.
• Bunny.net: Often considered by teams that want a leaner CDN for websites, straightforward delivery, and easier-to-understand commercial tradeoffs for static assets, media, or smaller web properties.
• Fastly: Frequently evaluated by developer-led teams that care deeply about fine control, sophisticated edge delivery logic, fast purge workflows, and programmable infrastructure patterns.

These are not hard rules. A small business site can choose Fastly if the workflow demands it, and an engineering-heavy app can choose Bunny.net if the requirements are simple. The point is to compare the operating model, not just the home page messaging.

How to estimate

The best CDN comparison is not a spreadsheet of checkmarks. It is a weighted decision model tied to your traffic, cacheability, and workflow. Use this four-step method.

1. Define your traffic mix

Break your workload into buckets rather than looking at a single monthly bandwidth number:

• Static assets: CSS, JavaScript, fonts, downloadable files
• Images and media: product images, resized variants, video segments
• HTML pages: cacheable marketing pages, blogs, landing pages
• Dynamic paths: carts, checkout, logged-in areas, search, account pages
• APIs: public endpoints, authenticated APIs, edge-cacheable GET responses

This matters because website caching value depends on how much of your traffic can be served from edge caching rather than repeatedly hitting origin.

2. Score technical fit before price

Create a simple weighted score out of 100. A typical model looks like this:

• Cache controls and rules: 20
• Purge flexibility: 15
• Ease of setup and maintenance: 15
• Performance observability: 10
• Security and platform extras: 10
• Developer extensibility: 10
• Support and documentation fit: 10
• Commercial predictability: 10

Then reweight it for your environment. A WordPress publisher may care more about HTML caching, cache purge, and simplicity. A SaaS team may care more about API caching strategy, logs, and programmable rules. A WooCommerce store may put heavier weight on bypass logic, cookie-aware behavior, and safe purge controls.

3. Estimate likely cost drivers

Because vendor pricing changes over time, use a cost worksheet instead of hard-coded assumptions. Ask these questions:

• How many GB or TB of egress will the CDN serve monthly?
• What share of requests are cache hits versus origin fetches?
• Will you pay for image optimization, edge compute, WAF, bot controls, or advanced analytics?
• Do you need real-time logs, long retention, or SIEM export?
• Will traffic be concentrated in one region or globally distributed?
• Do you expect burst events, frequent purge storms, or seasonal traffic spikes?

Your real cost is not “CDN price per GB.” It is the combined cost of delivery, platform features, and any remaining origin load you fail to offload.

4. Estimate operational savings

A better CDN can reduce more than bandwidth. It can also cut origin CPU usage, improve TTFB, reduce incident noise, and simplify release workflows. When comparing managed caching solutions, include soft savings:

• Less time troubleshooting opaque cache behavior
• Lower hosting cost from reduced origin requests
• Faster cache purge for editorial or deployment workflows
• Fewer plugin conflicts in WordPress caching setups
• Better resilience during spikes because the edge absorbs more traffic

This is especially important if your current setup already “works,” but works with too much manual effort. For help building the business case, see How to Prove Cache ROI to Finance Teams When AI Promises Miss the Mark.

Inputs and assumptions

This section gives you a practical framework you can reuse whenever pricing inputs change.

Traffic inputs

• Monthly bandwidth: Start with current CDN or host analytics. Separate static assets from HTML and API responses if possible.
• Request volume: Some workloads are request-heavy even when bandwidth is modest, especially APIs and image-heavy pages.
• Regional mix: Global delivery may affect both performance and pricing model fit.
• Peak-to-average ratio: A launch-driven traffic pattern creates different stress than steady traffic.

Cacheability inputs

• Static asset cacheability: Usually high if filenames are versioned and cache-control headers are correct.
• HTML cacheability: Varies widely. Marketing pages and blogs can often benefit from reverse proxy cache rules. Logged-in or personalized pages often bypass edge cache.
• API cacheability: Public GET endpoints, catalog data, and derived payloads may be edge-cacheable with careful headers.
• Cookie and personalization footprint: This is often the deciding factor for WordPress caching and WooCommerce cache rules.

Feature assumptions

Do not treat all CDN features as equal just because the label matches. Ask what you actually need:

• If you need basic website caching, almost any major provider can cache static assets well.
• If you need HTML edge caching, compare page rules, header overrides, cookie bypasses, and stale strategies.
• If you need purge precision, evaluate whether purge-by-tag, surrogate key style workflows, or prefix invalidation matters.
• If you need developer control, compare APIs, infrastructure automation, and edge logic options.
• If you need security consolidation, a broader platform may offset the cost of other tools.

Operational assumptions

Include the cost of running the platform day to day:

• Who owns configuration: developer, sysadmin, marketer, or mixed team?
• How often do cache rules change?
• How often do you deploy?
• How often do you publish content that requires purge?
• How easily can your team debug headers and cache status?

If your team is small, operational clarity may matter more than maximum power. If your team is platform-heavy, richer control may pay off.

A practical side-by-side lens

Use the table below as a decision lens rather than a fixed verdict:

Worked examples

These examples are intentionally assumption-based so you can substitute your own traffic numbers and feature needs.

Example 1: Content-heavy marketing site

Profile: Mostly static assets and cacheable HTML, occasional campaign spikes, no logged-in area.

What matters most: Easy setup, strong cache-control headers support, straightforward purge, decent analytics, predictable cost.

Likely shortlist outcome: Cloudflare and Bunny.net often rise quickly here because the workload is simple. Fastly may still be a fit, but only if your team values deeper control enough to justify it.

Decision check: If your HTML can be cached safely and your deployment process only needs simple purge, prioritize ease and commercial clarity over advanced edge programmability.

Example 2: WooCommerce or dynamic WordPress store

Profile: Static assets cache well, some product and category pages may be edge-cacheable, but cart, checkout, account, and personalized paths must bypass cache.

What matters most: Cookie-aware rules, safe bypasses, predictable cache purge after catalog changes, image delivery, and minimal plugin conflict.

Likely shortlist outcome: Cloudflare often appeals if you want broader platform controls around the site. Bunny.net can be attractive if your store is smaller and you want simplicity. Fastly becomes more compelling when your storefront architecture is more customized and your team can take advantage of deeper edge logic.

Decision check: Do not compare these providers using only homepage speed tests. For WooCommerce cache rules, the real question is whether the platform helps you avoid serving stale or personalized content incorrectly while still keeping product and category traffic off origin.

Example 3: API-heavy SaaS application

Profile: Mix of static assets, app shell delivery, authenticated APIs, some public or semi-cacheable GET responses, frequent deploys.

What matters most: Header control, surrogate or tag-based invalidation patterns, real-time observability, programmable behavior, and repeatable automation.

Likely shortlist outcome: Fastly often enters the conversation strongly for advanced engineering use cases. Cloudflare can also be very attractive if your team wants a broader edge platform and can map its controls cleanly to your app model. Bunny.net may be enough if your edge logic remains narrow and your main goal is efficient delivery rather than a programmable edge layer.

Decision check: Estimate not just delivery cost, but the cost of delayed purges, weak debugging, or limited edge logic. Those operational penalties accumulate quickly in API and app environments.

Example 4: Small business site with modest traffic but global visitors

Profile: Limited engineering time, basic CMS, mostly static content, occasional lead-generation pages.

What matters most: Simplicity, low administrative overhead, basic website speed optimization, and a clean path to managed caching solutions.

Likely shortlist outcome: Bunny.net often deserves serious consideration on simplicity grounds. Cloudflare may win if DNS, proxying, and extra platform services reduce tool sprawl. Fastly is less likely to be the first pick unless the business has unusual requirements or a technical operator who wants fine-grained control.

When to recalculate

You should revisit this comparison whenever the inputs that drive fit or cost change. This is what makes the topic worth returning to: the right answer can shift even if the vendors themselves remain familiar.

Recalculate your Cloudflare vs Bunny.net vs Fastly decision when any of the following happens:

• Pricing changes: New transfer rates, plan changes, or add-on packaging can alter the total picture.
• Traffic shape changes: More media, more API traffic, more global users, or higher spikes can expose a different pricing or performance profile.
• Cache hit ratio drops: If more requests reach origin, your effective cost changes even if the CDN invoice does not move much.
• Publishing workflow changes: More frequent deployments or content updates increase the value of purge tooling.
• Application architecture changes: Moving to headless, adding personalization, or introducing regional routing may require different edge controls.
• Security consolidation becomes a priority: The best CDN comparison may change if you want DNS, WAF, bot controls, and edge caching under one vendor.

Here is a practical quarterly review checklist:

1. Export 90 days of bandwidth, requests, cache hit ratio, and origin fetch volume.
2. List every paid feature you actually use versus features you are carrying but ignoring.
3. Review your top 20 cache misses and top 20 purge events.
4. Measure whether TTFB and origin load improved after recent rule changes.
5. Update your weighted scorecard based on current business priorities.
6. Re-run one pilot path or hostname on the shortlist vendor if the gap is meaningful.

If your environment includes specialized workloads such as dashboards, operational logs, SaaS multi-surface apps, or industrial systems, your cache strategy may need a more custom lens than a generic CDN comparison.
