Which one is cheaper?

One or both use custom pricing, so it depends on your specific needs.

Can I use either one for free?

Deno Deploy has a free plan. Fly.io doesn't — though they do offer a free trial.

Different approach here. Fly.io uses usage-based pricing, while Deno Deploy goes with hybrid. That changes the math depending on your team size and usage.

Which one is a better deal?

Depends on what you need. Fly.io: Positioned as the developer-friendly alternative to AWS/GCP complexity with transparent, granular pricing. They're competing on simplicity and predictability rather than being the cheapest option. Deno Deploy: Sitting between $20 and $200 with a big gap in between, Deno Deploy isn't trying to be the cheapest edge platform out there — that Builder tier price point signals they're chasing teams building platforms-on-platforms (agencies, SaaS companies embedding Subhosting) rather than casual indie devs. They're competing more with Vercel and Cloudflare Workers for serious workloads than with hobbyist-friendly tools.
