Which hosting platform would you pick for a small production app: Render vs Railway vs Cloudflare Workers?

I’m building something like a inventory management app and website — authenticated users, a Node/TypeScript API, PostgreSQL, background jobs/cron, and potentially a few thousand users over time.

Currently considering **Render, Railway, and Cloudflare Workers**.

For a production app where reliability, scaling, DB latency, and predictable costs matter, which one would you choose and why?

Would you recommend something else like **Fly.io, AWS, or Vercel + another backend** instead?

Curious to hear from people who’ve actually run production workloads on these.

I'm looking for a workable solution or recommendations to provide a client's credentials to that client in the event of my untimely demise or absence. (E.g. hit by a bus - falling out and need to hand everything over, etc.) I also don't want to mix MY credentials with theirs.

So my primary work isn't webdev, but I do some for clients as part of my general services. Generally this means me building everything from scratch and leaving the client(s) out of the day-to-day management entirely.

I'm trying to figure out the best way to have their business' credentials saved, updated as they are changed, and set aside for if I get "hit by a bus" so they won't be locked out of everything.

I also don't want them "futzing" with things (because some of these clients have impulse control issues and would 100% give their credentials to someone on Fiver to update a paragraph on their website at 2am when I don't answer my phone.) So access while I'm not dead or fired isn't a real option.

I understand that I can make "organizations" in some of the password managers and have emergency hand-over to pre-selected people, but I work alone, and don't "have a lawyer" that can manage it for me.
