Alongside Cloudflare’s EmDash launch, a wave of write-ups have made a striking promise to small businesses: move your WordPress site to a serverless CMS and cut running costs by as much as 85%. One widely shared analysis from the agency Oflight lays out a scenario where a WordPress site costs roughly ten times what the same site would cost on EmDash. The savings are real in the right conditions. They are also a best-case, vendor-shaped scenario, and a small business deciding on real money deserves the honest version.

Where serverless genuinely saves money

The core idea is sound. Traditional WordPress hosting means paying for a server that runs whether anyone visits or not. A serverless setup on Cloudflare Workers bills mostly for actual usage, and scales to zero when the site is idle. For a low-traffic small-business site, a brochure site, a local service, a small shop, that difference is genuine. You stop renting a machine to sit mostly empty. Static Astro pages served from Cloudflare’s edge are also fast and cheap to deliver, and you shed the steady drip of costs that cling to WordPress: managed hosting tiers, backup add-ons, security plugins, and the maintenance hours that plugin updates quietly consume.

So the direction of the claim is correct. A simple, low-traffic site can run for a very small monthly bill on serverless infrastructure. That part is not marketing.

What the 85% headline leaves out

The problem with a number like “85% cheaper” is what sits outside the comparison. A few things the tidy tables tend to omit:

  • The numbers are a chosen scenario. The widely cited figures come from a vendor-aligned write-up, use one specific traffic level, and are quoted in Japanese yen for a particular market. Your real bill depends on your traffic shape, your media, and your database use, not on someone else’s example.
  • Migration is not free. Moving off WordPress costs developer time, and it costs SEO risk. If a migration drops rankings because redirects and metadata were not handled properly, the lost traffic dwarfs any hosting saving. We have written separately about where WordPress migrations quietly lose rankings.
  • Maturity is a cost. EmDash is a v0.1.0 preview with a near-empty plugin ecosystem. “Cheaper hosting” is small comfort if you then pay a developer to rebuild the booking form, the newsletter signup, or the payment flow that a WordPress plugin gave you for free.
  • Your time is the real WordPress cost. For most small businesses the expensive part of WordPress was never the hosting. It was the hours spent on updates, breakages, and security worry. Serverless can reduce that, but so can simply running fewer plugins and a proper maintenance routine on the site you already have.

None of this means the savings are fake. It means “85%” is the top of a range that assumes everything goes right and counts only the hosting line, while the decision that matters counts the whole picture.

What a small business should actually optimise

Hosting cost is rarely the number that decides whether a small-business site succeeds. Before you replatform to chase a cheaper bill, the higher-leverage questions are almost always about visibility and conversion, not infrastructure:

  • Are you getting found at all, in Google, in Maps, and increasingly in AI answers?
  • Does the traffic you already have convert, or does it bounce off a slow, unclear page?
  • Is your existing site leaking rankings through the ordinary problems, missing redirects, thin pages, broken structured data, that an audit surfaces in an afternoon?

Fixing those moves revenue far more than shaving a hosting bill. A fast serverless site that nobody finds is still invisible. If cost is genuinely your pressure point, the honest first step is not a migration, it is a look at where your current site wastes money and misses customers, which is the core of our small-business promotion work.

EmDash is worth watching, and cheaper infrastructure is a real trend, not a gimmick. Just make the decision on the full math, not the headline. If the AI and agent angle is what caught your eye rather than the price, we cover what an AI-native CMS means for getting found separately.
