The React SDK gives you useUser(), a pre-built profile dialog, a sign-in component, and live feature flags from the same provider. Server-side, every SDK speaks the same REST.

[01]

Big companies don't store their own users in someone else's database.

Why are you? Imagine paying to give your users away so someone else can monetize their data. Sessions, recovery emails, audit trail. The most sensitive table you own. Keep it in your stack.

[02]

Per-MAU pricing punishes you for shipping.

Hosted auth is fine until renewal. Tier changes can wipe out your runway. Run it yourself; pay for the hardware.

[03]

If you can't read it, you can't trust it.

Open source. Plain SQL migrations. Documented data model. Audit it, patch it, fork it.

One command.
Then it's yours.

One repo, one compose file, one Postgres. The binary embeds its own admin UI; schema, migrations, secrets, and the first admin user all bootstrap themselves.

terminal

# set MANYROWS_FROM_EMAIL in .env, then:
docker compose up -d
# → localhost:8080 · first registrant = super-admin
