If you landed here weighing StackPath against BunnyCDN and Cloudflare for a WordPress site, the first thing you need to know rewrites the whole question: StackPath no longer exists. Its CDN (which absorbed the old MaxCDN and Highwinds networks) stopped serving traffic in November 2023, and the company liquidated its remaining assets in mid-2024. There is no signup, no support, and no migration assistance. Akamai picked up a sliver of enterprise customers, but for the typical WordPress owner, StackPath is a dead end.

So this comparison is really a two-horse race in 2026 — bunny.net (formerly BunnyCDN) versus Cloudflare — with StackPath serving as a cautionary tale about what happens when you build your stack on a provider that gets sold and shuttered. Below, I'll cover where StackPath users should go, then give you the real decision framework between the two CDNs that are actually worth your time.

What StackPath users should do right now

If you still have a WordPress plugin pointing rewrite URLs at a stackpathcdn.com or stackpathdns.com hostname, those requests are failing silently — your visitors are loading assets from your origin (or not at all). Audit your site for hardcoded StackPath URLs in the database, your CDN plugin (W3 Total Cache, WP Rocket, or a standalone CDN Enabler), and any theme or page-builder settings.

Disable the StackPath integration in your caching plugin so it stops rewriting asset URLs to the dead hostname.
Search-replace the CDN domain in your database using a tool like Better Search Replace or WP-CLI (wp search-replace), pointing assets back at your own domain or your new CDN.
Pick a replacement — for almost everyone that's bunny.net or Cloudflare, both of which I cover next.

The fundamental difference: pull-CDN vs full reverse proxy

Bunny.net and Cloudflare solve overlapping problems with completely different architectures, and that distinction drives every other trade-off.

Bunny.net is a classic pull-zone CDN. You create a pull zone, point it at your origin, and Bunny caches and serves your static assets (images, CSS, JS, fonts) from its edge. Your domain still resolves to your host; you serve assets from a Bunny hostname (or a CNAME'd subdomain like cdn.yoursite.com). Your origin server still renders every page. Bunny accelerates the heavy static payload without sitting in front of your whole site.

Cloudflare is a full reverse proxy. You move your DNS to Cloudflare, and all traffic — HTML, assets, API calls, login attempts — flows through its network before reaching your origin. That gives Cloudflare a much bigger surface area to work with: a WAF, DDoS mitigation, bot management, SSL termination, and page-level caching all happen at the edge. The cost is that Cloudflare becomes a chokepoint in your request path, for better and worse.

WordPress integration: how each actually plugs in

Bunny.net

Bunny's WordPress story runs through its official integration or a generic CDN plugin. The cleanest path is the dedicated Bunny.net plugin or pairing a pull zone with WP Rocket / W3 Total Cache, which rewrite your asset URLs to the Bunny hostname and handle cache purging on content updates. Because Bunny only touches static files, your dynamic WordPress logic (carts, logged-in sessions, AJAX) is untouched — there's nothing to break, and no risk of accidentally caching a personalized page.

Bunny also sells Bunny Optimizer (around $9.50/month per site), which does on-the-fly WebP/AVIF conversion, responsive image resizing, and CSS/JS minification at the edge. For an image-heavy WordPress site, that's often the single biggest Core Web Vitals win, since unoptimized hero images are the most common cause of a slow Largest Contentful Paint.

Cloudflare

Cloudflare's marquee WordPress feature is Automatic Platform Optimization (APO). Installed via the official Cloudflare WordPress plugin, APO uses Cloudflare Workers to cache your full HTML — including dynamic pages — at the edge, while intelligently bypassing the cache for logged-in users and cart/checkout flows. Cloudflare's own post-launch testing reported roughly a 70%+ reduction in TTFB at the 90th percentile by serving HTML from the edge rather than your origin.

APO costs $5/month on the Free plan and is bundled into Pro, Business, and Enterprise at no extra charge. If your host already runs slow (shared hosting with a 600ms+ TTFB), APO is transformative because it stops most visitors from ever hitting your origin. The catch: edge HTML caching needs care with plugins that output per-visitor content, so test logged-out and logged-in states after enabling it.

Pricing: flat tiers vs pay-as-you-go

This is where the two diverge most sharply.

Cloudflare has a genuinely generous free tier — unlimited bandwidth, basic CDN, shared SSL, and DDoS protection at $0. Paid plans (Pro ~$20–25/mo, Business ~$200/mo) add image optimization, advanced WAF rules, and bundled APO. The pricing is flat and predictable: you pay per zone, not per gigabyte.
Bunny.net is pure pay-as-you-go, billed per gigabyte by region — roughly $0.01/GB in North America and Europe, scaling up to ~$0.03–0.06/GB in South America and Asia-Pacific, with a $1/month account minimum and a discounted Volume tier (~$0.005/GB) for high traffic. A small blog might pay $1–3/month; a busy media site could pay $20–50.

The honest takeaway: for a low-to-moderate traffic WordPress site, Cloudflare's free tier is almost impossible to beat on price. Bunny only wins on cost at scale or when you specifically want usage-based billing you can predict from your analytics.

Performance and network footprint

Cloudflare operates one of the largest edge networks on earth — data centers in 330+ cities — so a visitor is almost always close to a PoP. Bunny runs a smaller but still global network (100+ PoPs) and is frequently praised in independent CDN benchmarks for low, consistent latency, sometimes edging out larger networks on raw asset-delivery speed thanks to a leaner, performance-focused stack.

In practice, both will get your static assets delivered fast enough that the bottleneck moves elsewhere — to your origin's TTFB, your render-blocking resources, or your unoptimized images. Don't expect either CDN alone to fix a bloated 4MB page; a CDN accelerates delivery, it doesn't shrink what you're sending. Pair whichever you choose with image optimization and good caching, and aim for the Core Web Vitals targets that actually move rankings: LCP under 2.5s, INP under 200ms, CLS under 0.1.

So which one?

Here's the practical call for WordPress in 2026:

Choose Cloudflare if you want a free or flat-priced solution, you need a WAF and DDoS protection baked in, or your hosting TTFB is slow and you want APO to serve full pages from the edge. This is the right default for most blogs, brochure sites, and small businesses.
Choose bunny.net if you want a lightweight pull CDN that doesn't proxy your entire site, you prefer transparent per-GB billing, or you want best-in-class image optimization via Bunny Optimizer without handing your whole DNS over to a single proxy.
Choose StackPath — you can't. It's gone. If you're reading an older tutorial that recommends it, the tutorial is stale.

If you can't decide between the two live options, you don't have to commit blind: Cloudflare's free plan costs nothing to trial, and Bunny's $1 minimum lets you spin up a pull zone for pocket change. Run real traffic through each for a few days, check your TTFB and LCP in PageSpeed Insights and your Search Console Core Web Vitals report, and let your own numbers decide. Just don't build on a provider that might be the next StackPath — both of these are stable, well-funded, and actively developed in 2026.
