Tigris and egress billing

I’m evaluating tigris (and fly itself) for my upcoming project.

I see on the tigris docs that there are no egress fees. However, fly does charge egress fees, and it only calls out that data transfer to tigris is not billed. It’s also unclear on the pricing page for fly tigris:

This pricing can change as data transfer costs are worked out between Fly.io and Tigris.

So I’m curious, given the following line implying tigris deploys on fly:

Tigris is a globally caching, S3‑compatible object storage service built on Fly.io infrastructure.

Will provisioning tigris storage with

fly storage create

fly storage create

subject the storage to fly’s egress fees? I’m comparing vs. Cloudflare R2 which is already slightly cheaper as below:

Tigris

- Data Storage: $0.02 / GB / month
- Class A Operations: $5.00 / million requests
- Class B Operations: $0.50 / million requests
- Data Transfer (Egress): Free

Cloudflare R2 (Standard)

- Data Storage: $0.015 / GB / month
- Class A Operations: $4.50 / million requests
- Class B Operations: $0.36 / million requests
- Data Transfer (Egress): Free

Assuming egress is free for both, I’d like to go with tigris to have everything contained in fly. But if fly’s egress fees apply, I will likely need to go with R2.
