On free tier, Cloudflare Workers is Free: 100,000 per day and Fly.io is No free plan: First 10GB free each month of egress. On cheapest paid plan, Cloudflare Workers is $5.00 per month (Workers Paid) and Fly.io does not publish it. On rate above what's included, Cloudflare Workers is +$0.30 per additional million requests, +$0.02 per additional million CPU milliseconds and Fly.io is $0.15/GB per month for volumes, $0.08/GB per month egress. StackTab sells neither of these and takes no referral fee on either: it scores them. Every figure was read off the named company's own page on or since 2026-09-28; the URLs and the dates are at the foot of this page, and a job re-fetches each one on a schedule and fails when a figure is no longer on the page it came from.

“Not published” means that company does not state the figure on the page cited at the foot of this page. It is not a claim that no such figure exists. A company that publishes no limit most likely has none, but “most likely” is not a fact, and this table prints what was read rather than what was inferred.

Cloudflare Workers: Bandwidth is your dominant cost. Cloudflare charges nothing for egress at any volume, which is not a cheaper rate than the others: it is the absence of the line that dominates their bills, and no amount of optimisation elsewhere closes that gap. Fly.io: You need the app running in several regions and close to the user, and you are willing to think about machines rather than a platform. Fly.io has no plan fee at all, so a small multi-region deployment costs what its machines cost, and nothing else in this table prices region-by-region placement as an ordinary thing to do.
StackTab does not sell any of these and has nothing to gain from which one you choose: it scores them. Each case below is the one that option genuinely wins.

Prices and limits move, and a page quoting a stale one is worth less than a page quoting none. Every source is printed here so a reader can check it against the day they are reading this, and a job re-fetches each of these URLs on a schedule and fails when a figure above no longer appears on the page it came from.
