Last I heard, the default limit was twenty-ish, but you can email Support, ahead of time, to get that lifted. I actually see an explicit bound displayed on the dashboard lately:

 ![machines count and limit panel from the fly.io dashboard, shows 4 used out of a 50-machine limit](https://global.discourse-cdn.com/fly1/original/3X/d/6/d672978df8c5880ace05e3476a2ac8225523405c.png)

For _thousands_ of Machines, I’d also suggest consulting the (excellent) new [capacity API.](https://community.fly.io/t/regional-capacity-in-machines-api-and-flyctl/24843) Even the largest regions have only ~2000 free.

(This is when the new [region-fallback](https://community.fly.io/t/route-and-replay-to-regions-in-order-of-preference/25871) feature comes in handy, I’m guessing.)

Finally, this is just my personal opinion, but at that scale, you’ll probably want a formal [Fly Support](https://fly.io/support) plan. Most of those include real-time architecture advice sessions, which typically repay the (relatively small) extra outlay on their own—in terms of cost-savings, etc., canary in thought balloon.
