KeyCDN bills at roughly $0.04 per GB in North America and Europe as of Q1 2026, with no monthly minimum. That flat $40/TB rate looks clean on paper, but once you push real volume, the math turns hostile fast. The strongest KeyCDN alternatives in 2026 land between $2 and $10 per TB at scale, which means a media or software-distribution workload moving 500 TB monthly is the difference between a ~$20,000 bill and a ~$1,500 one. This article gives you the current per-GB pricing for 11 providers, a workload-to-CDN decision matrix, the migration sequence that avoids cache-warming penalties, and the hidden line items that distort every headline rate.
KeyCDN's pull-zone model and instant purge remain solid for small sites. The pressure comes from three directions that sharpened over the last year.
Pricing figures below reflect public list rates as of Q1 2026. Real contracts vary with commit volume and region mix; Asia-Pacific and South America egress routinely costs 2–4× North American rates across every provider, so a single blended number hides real exposure.
We weighted five dimensions, with cost and performance carrying the most weight because savings are meaningless if TTFB regresses and conversions drop.
Rates are list prices for standard egress (North America / Europe) as of Q1 2026 unless noted.
| Provider | Indicative egress (per GB) | Best fit |
|---|---|---|
| BlazingCDN | $0.004 down to $0.002 at 2 PB+ | Media, SaaS, gaming, software distribution at scale |
| Bunny.net | $0.005–$0.01 (volume tier), ~$0.03 standard | Small to mid sites wanting simple pay-as-you-go |
| Cloudflare | $0 metered egress on standard plans (fair-use) | Web apps, edge functions, security-first stacks |
| Amazon CloudFront | ~$0.085 first tier, ~$0.02 at high volume | Deep AWS integration, existing AWS billing |
| Fastly | ~$0.08–$0.12, lower on commit | Programmable edge, VCL/Compute workloads |
| Gcore | ~$0.018–$0.04 by region | Streaming and APAC-heavy delivery |
| Google Cloud CDN | ~$0.08 first tier, scaling down with cache fill rates | GCP-native architectures |
| Akamai | Negotiated, commit-based | Large enterprise, complex compliance |
| CDN77 | Commit-based, ~$0.01–$0.03 effective | Video delivery, predictable commits |
| Azure CDN / Front Door | ~$0.08 first tier, scaling on volume | Azure-native enterprise apps |
| DigitalOcean / Spaces CDN | $0.01 over generous included allotment | Small projects already on DO |
The headline rate that matters most for the cheapest KeyCDN alternative question: committed-volume providers like BlazingCDN start at $4 per TB ($0.004 per GB) and drop to $2 per TB ($0.002 per GB) past 2 PB. Cloudflare's $0-egress model wins on simple web assets but enforces fair-use limits that disqualify heavy video. The hyperscalers stay expensive on their first tier, where most mid-size workloads actually live.
Generic "best CDN" lists rank providers as if every workload were identical. They are not. Match the provider to your traffic shape.
For that last profile, BlazingCDN delivers stability and fault tolerance comparable to Amazon CloudFront with a 100% uptime commitment, flexible per-route configuration, and fast scaling under demand spikes — at a fraction of the transfer cost. Sony is among the clients running on that infrastructure, which is a useful signal for teams weighing reliability against price.
The risk in any CDN cutover is a cold edge cache hammering your origin the moment traffic shifts. Sequence the move to avoid it.
Headline per-GB rates hide the real bill. Watch for per-10,000-request fees, log-export and real-time streaming surcharges, premium support tiers gated behind enterprise plans, TLS certificate add-ons, and minimum monthly commitments that you pay regardless of usage. A provider that looks $0.01/GB cheaper can cost more once request fees and log charges land.
Cheap today is not enough if the platform stalls. Confirm mature HTTP/3 over QUIC, edge compute you can actually deploy to, real-time log streaming for observability, and a pricing model that scales down as you commit rather than locking you into a single flat rate. The providers that cut egress through 2025 did so because volume economics now favor the buyer who negotiates.
For committed volume, BlazingCDN starts at $4 per TB ($0.004 per GB) and falls to $2 per TB ($0.002 per GB) above 2 PB monthly. For tiny sites with no commitment, Cloudflare's standard plan and Bunny.net's pay-as-you-go are effectively cheaper because you avoid any monthly floor.
Yes. Bunny.net and DigitalOcean Spaces CDN both bill purely on usage with no minimum commit, mirroring KeyCDN's model at lower rates. If your volume is predictable and large, a committed-volume contract will beat pure pay-as-you-go on effective per-GB cost.
At KeyCDN's ~$0.04/GB, 500 TB/month runs roughly $20,000. A committed provider at $0.003/GB for the same volume runs about $1,500. The savings widen as volume grows, which is why high-egress media and software workloads see the largest gains.
Not if you validate first. Benchmark global TTFB and cache-hit ratio on a staging subdomain before cutover, then shift traffic gradually with weighted DNS. Performance regressions almost always show up in staging if you test the same URL set and header rules.
Workloads with high object sizes and near-99% cache-hit ratios are dominated by egress cost, so the lowest committed per-TB rate wins. BlazingCDN, CDN77, and Gcore are the strongest fits for streaming and software distribution.
Only if your application runs logic at the edge — auth, A/B routing, request rewriting. If you serve mostly static assets, prioritize egress price and cache behavior; edge compute maturity matters more for API and dynamic workloads where Fastly and Cloudflare lead.
Before you sign anything, instrument the comparison properly. Pull your top 100 URLs by request volume, stage them against your two finalist CDNs, and measure TTFB at p50 and p95 from at least three regions matching your real audience distribution. Then model the bill: take last month's actual egress by region and apply each provider's per-region rate, not the blended NA headline. The gap between the cheapest list price and the cheapest effective price is where most teams overspend. What does your 500 TB month actually cost on each finalist?
