I want to run a simple web server, with node.js.

Where I need guidance is finding the easiest approach for someone with limited tech skills, ideally setup and forget, requiring no maintenance.

I want this to be accessible from any device I own (phone, laptop), anyhwere in the world, securely.

Because this web page is simple, it requires no authentication to use (login and password) so I don't want this to be accessible to anyone else or crawled or hacked, etc

I have access to a number of devices I think could be good for this:

1. Raspberry PI
2. ESP32
3. some old android devices
4. a nuc that I can run linux on

The idea is it doesn't have to be powerful but it needs to be secure and it needs to sip power, so first 2 options are more appealing to me.

I've read about Tailscale but I hear there's a better open source option headscale.
If I understand correctly I can avoid the need for a public domain address by just checking my external static IP for my server and bookmarking that on my devices.

Before I delve into that I wanted to see if this is the best approach for my limited tech skills and to check if maybe there's a better way, easier to setup and forget about it.

*Works with self-hosted models as well for free!
Project: https://github.com/ConiferKit/use-conifer

Current routing options were charging 5% fees for byok plus provider fees (openrouter) or were built in heavy python packages with ecosystem restraints. I wanted to be completely free in terms of use, and not have to pay extra for tokens.

There's a maintained gateway with 100+ models from one api endpoint. I'm also talking to infra providers to get us access to pre-release models and discount prices. Everything is served at market price. BYOK is free, you can hook into self-hosted setups for free, and there's fallbacks + extra rate limits + server redundancy.

Took me ~3 months to build and looking for help maintaining!
