BYOI
Bring Your Own Infrastructure

Connect your own infra.
We raise your MAU ceiling instead.

Every component you bring — database, email delivery, cache — reduces HelloJohn's operating cost for your account. We translate that directly into higher MAU limits, at no extra charge.

SMTP
Biggest impact
+20kMAU / tenant

Your email delivery, your domain, your sender reputation. Plug in your SMTP and take full ownership of every auth email.

# tenant.yaml
smtp:
host: "smtp.sendgrid.net"
from: "auth@acme.com"
password_enc: "enc:..."

Database

+3kMAU

Your own PG or MySQL. Removes connection overhead from our shared pool.

user_db:
driver: "postgres"
dsn_enc: "enc:..."

Redis

+1kMAU

Dedicated cache. Faster session lookups, lower latency on every auth request.

cache:
driver: "redis"
host: "redis:6379"
