“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.

When should I pick Cloudflare Workers, and when Fly.io?

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.

When each of these is the right pick

What was checked, and whenverified 2026-09-28

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.
