Yes you absolutely can use Railway to run your Laravel app in production! may I ask what made you think that you possibly couldn't?

Description of plans, mentioned shared memory.

No they didn't, they mentioned shared storage, and even so, that's shared empherial storage in the sense that everything you run can't use more than 100gb of empherial storage.

I use service amezmo I am dissatisfied with the service of amezmo

I meet railway potential service to replace amezmo for railway

Just so you know, Railway does not offer managed hosting, you will have to know how to host a dockerized php app, if that's something you aren't too familiar with then you might not have the smoothest experience.

Understand. Thank you !
