04 / Why generate it
Why generate it instead of buying it.
Clerk and Auth0 charge per monthly active user. Past 10K active users that's thousands a month just for logins. Supabase Auth is free up to 50K monthly active users and can run on your own servers; WebTwizz builds everything around it.
Multi-tenant security is one of the easiest things to get wrong. Rules enforced by the database itself are the right tool; WebTwizz writes them from your prompt instead of you writing them by hand.
FAQ
Questions about Multi-Tenant SaaS.
Everything you need to know before you generate it. Anything else, our team is one email away.
Every record is tagged with its workspace. Database rules check that the person asking belongs to that workspace before returning the row. Even an attack that gets past your app can't reach another customer's data, because the database itself refuses.
Owner enters an email + role, and a one-time invite is created. Email goes out via Resend with the accept link. Clicking it signs the person in with Supabase, adds them to the workspace, and removes the invite. If the email already has an account, they auto-join on next login.
Yes. A user can belong to any number of workspaces, with a role in each. The app shows a workspace switcher in the top bar; switching changes the active workspace and the data shown. Standard B2B SaaS pattern.
Each workspace has its own Stripe customer record and subscription. The owner pays. Member seats may add per-seat charges through Stripe usage billing if your pricing scales by team size. WebTwizz sets up either flat-fee or seat-based.
