For django, they should really contribute to 2 scoops django cookie cutter program, so that you can get an out of the box django instance that can just deploy to Fly.io.
Their problem right now isn't adding more customers - they seem to have more than they can handle!
If I were them I'd focus as many resources as possible on making the stack rock-solid, and away from acquiring more customers or adding more capabilities.
In fact I'd try to down-scope some features if at all possible, like the example they give of disabling app deploys while they're doing platform updates.
We use fly.io at a small scale and it's worked really well for us, but the money is in customers at a larger scale who must have 100% reliability.
I needed a cookie cutter for my side projects so I've created one for sqlite that I actively use and a similar one for postgres. Both are very basic, contributions welcome.
May be wrong, but they seem to be very focused on interesting stacks like Elixir and RoR while building on Go/Rust. The corollary being neglect of the bread/butter stacks with high market share, like Python and Java/JavaScript. Don't think I've seen a blog post discussing those three beyond a passing mention?
Not the end of the world, but mildly disappointing. At least they are all in with Postgres and Linux, a great foundation.
