Mine is not exposed to the public internet, though some friends of mine do. I use a VPN when I need to access fresh data from the home server, otherwise both the Firefox client and Android client will generally keep a cache of the last data pull when they had connection (so it wasn't an issue the 4 or so years I didn't have a VPN yet).

If you choose a specific company's free tier, you can rely on reputation and switch if they misbehave (e.g. they exfiltrate your secrets, log all your activities, build a profile on your workload behavior, etc). But if you don't know where your workload being deployed, the operator has less incentive to treat your compute with respect.

Means this is really only useful for nearly-public workloads, where tampering is not a critical failure mode.

The "strict guardrails" don't work. Never did.

I've used enough Claude coded applications that I wouldn't trust that with a backup, unless it had extensive tests along with it.

But if OpenRouter does better (even though it's the same sort of API layer) maybe it's worth it?

Your at-rest format allows you to use any tool to edit it. The specialized editor becomes a preferred tool, but not the only tool nor the most important one. Markdown and it's ecosystem came before the editor.

Seems like a worse version of urbexology.com

I'm pretty sure if you use the site you're using GitHub Copilot in some way, so your question becomes irrelevant.
