There's nothing public, but it's a SaaS application written with actix-web, askama and sqlx.

One of the big slow downs comes from a single crate (async-stripe). In retrospect, I should just use reqwest and serde to do everything with Stripe's API manually and not use any crate at all (especially if it cuts the build time in half).

I see, thanks. I assume `async-stripe` is auto-generated from some IDL, those crates sometimes bump into some pathologial pattern, I'll check it out.

`actix-web` itself should be fine, `sqlx` can be heavy if you use its compile time features, I'd assume `askama` is heavy as well, just based on the description (it generates rust code at compile time).

Otherwise it depends on how the code is structured (e.g. how generic it is, how deep types or complicated futures it creates).
