How to use multiple Happier servers from your phone (work / personal)

I started using multiple Happier servers pretty early (cloud + a self-host, and later a work server), and I hit the same confusion everyone hits:

A link opens, a notification pops, and you’re suddenly thinking:

“Wait — which server am I on right now?”
“Why are my sessions gone?”
“Why did that connect flow send me to Server settings?”

This is the workflow that made multi-server feel predictable from my phone.

TL;DR

Treat each server as a separate “profile”: auth and sessions are server-scoped.
When something looks missing, you’re usually just on the wrong server.
Notifications/links are designed to not silently trust new servers; that’s why you sometimes land in Server settings.

What I mean by “multiple servers from your phone”

I mean you have more than one API/webapp target saved on your phone, for example:

Happier Cloud
your personal self-host
a work/company self-host

…and you want to switch between them without losing your mind.

What I tried first (and where I bounced off)

One server only: simplest, but not realistic if you want work/personal separation.
Bookmark different URLs: works, but I’d constantly end up in the wrong place after notifications.
Happier: has explicit server profiles and link handling that tries to keep you safe (it won’t silently add/trust a new server). Trade-off: you have to accept that “server switching” is a real part of the mental model.

If you’re new to Happier (what it is, and where to get it)

If you haven’t seen Happier before: it’s an open-source companion app (mobile/web/desktop) for AI coding agents like Claude Code, Codex, and OpenCode.

The session still runs on a machine you trust (laptop/server/dev box). Happier is where you monitor, steer, approve, review, and keep going from your phone.

The model that makes multi-server predictable

Three rules explain most “wtf just happened” moments:

A server profile is a saved API/webapp target.
Auth is scoped per server (logging into server A doesn’t log you into server B).
Your sessions are scoped per server (so switching servers can make your session list look empty).

Once you internalize those, most confusion turns into: “I’m on the wrong profile.”
