What's already running out of the box
A Postiz vps hosting deployment on Leneex brings up the full official stack in one pass — the Postiz app itself alongside PostgreSQL, Redis, Temporal, and Elasticsearch, each in its own container. Temporal handles the actual job scheduling behind every "post at 9am tomorrow" — it's not a cosmetic dependency, it's what fires your posts on time. Containers restart automatically if they crash, so a brief hiccup on one service doesn't take down the whole stack.
First login
The first account anyone registers on a fresh instance automatically becomes the Postiz organization owner — there's no pre-created admin login to look up. Open the app's URL, fill in an email, a password, and a company name on the sign-up screen, and you're in; if no outbound email provider is configured, Postiz activates the account immediately instead of waiting on a confirmation link. After onboarding, you'll land on an empty weekly calendar — that's expected, since nothing is scheduled and no social channels are connected yet.
What to do right after signing in
Close public registration once your own account exists, so nobody else can create a login on your instance — this is a manual step, not a default. Connecting a social channel requires provider API keys for most platforms (you register a developer app on X, LinkedIn, etc., and paste the keys into Postiz); eight platforms work without any extra configuration.
