Built my startup in Rust over the past year and I don't feel this pain. Stitching everything together yourself with actix-web was fine. Keycloak for auth, redis queues + workers for batch processing, SMTP for email, prom for monitoring, minjinja for templates, diesel ORM.

My main complaint was that there wasn't a CLI for generating resources. It's really annoying to write your own struct, generate the migrations, then write the CRUD routes every single time.
