Hosting SvelteKit on Fly.io
Pricing data as of 2026-10-12 · refreshed weekly
Fly.io is a paas platform. SvelteKit needs roughly 384MB RAM for a production server process, so the cheapest plan that actually fits depends on your traffic. Below is the cheapest Fly.io plan that fits each traffic level, computed from current list prices.
Note: the 384MB figure is for serving the built app. Production builds (next build and friends) are heavier and belong in CI or on your laptop — run them on the same small instance and you'll hit out-of-memory errors that say nothing about its serving capacity.
