Had a hobby project on heroku that I've moved to render.com pretty painlessly. It's a simple rust (actix + sqlite) project. I now have a go (gin + sqlite) project that is intended to replace the rust project that I also plan to set up on render. Overall it's been incredibly pleasant & I've had no issues.
To be clear though, these are very small/cheap projects between friends so I haven't needed to evaluate costs (beyond a few bucks a month) and I don't have any complex requirements beyond avoiding docker as much as possible.
I have more experience with Go + interact with it more regularly at work, whereas choosing Rust was mostly for fun/exploration. I realized I don't have the bandwidth currently to learn/debug a new language I'm unfamiliar with, especially when I don't have strong requirements for memory-safety or performance. This is just a hobby project for me, so I'm moving to a standard network stack that I'm comfortable with in Go.
I'm not completely abandoning Rust, however, as I am still using it for some other personal projects. I am having a good time writing CLI tools + cargo package management/build system is incredible.
