How to build a safe, scalable SaaS on Vibely

Building a prototype is easy. Building a SaaS that handles real users, real money, and real failure modes is the part most "build with AI" tutorials skip. Here is the checklist we run with every team that goes from demo to billing on Vibely.

Authentication

Use Supabase auth. Email + magic link covers 90% of cases. Add OAuth for the providers your audience already uses. Never roll your own.

Multi-tenancy

Pick a model on day one and stick with it. For most SaaS apps, row-level security on a shared schema is the right answer. Add an organization_id to every table and write RLS policies before you write the first query.

Billing

Stripe + a customers table that mirrors Stripe customer IDs. Use webhooks for state, not polling. Vibely's connectors panel will scaffold both halves for you.

Rate limiting

If you are exposing an API or letting users trigger expensive work, you need limits. Per-user, per-org, and per-IP. Redis or Postgres advisory locks both work; pick the one your stack already has.

Observability

Logs in one place. Errors in one place. A single dashboard you check before you push. The cheapest version of this is Sentry + a Supabase view; the expensive version is Datadog. Either is better than nothing.

Backups

Supabase point-in-time recovery is on by default. Test it once before you need it.

Security

Run the security view in Vibely on every PR. Patch dependency CVEs the same week they are reported. Rotate any secret that has been exposed, even if you think it has not been used.

Scaling out

You probably do not need to. Most SaaS apps run happily on a single Postgres for years. When you do, the path is read replicas first, then sharding by tenant.
