01
The problem
Every Base44 app comes with a backend: a database, logins, security rules and server code. That's brilliant. It's also a wall of new words if you've never built a backend before.
Entities. Row-level security. Backend functions. Connectors. You can use Base44 for ages without knowing what any of them really do, right up until something breaks.
What's BaaS? teaches it by doing, in small bites, with nothing to install.
02
The approach
Short lessons, real code, zero setup.
There are 12 lessons, about five minutes each. Every one follows the same four steps: say it, see it, try it, take it home. You get the plain-English version, watch it happen, have a go, then leave with a prompt you can paste into the Base44 builder.
No code needed. The code is there underneath for when you get curious.
03
What I built
It covers the whole backend: entities, auth, row-level security, backend functions, integrations, automations, connectors and agents.
A few bits worth pointing at:
What's inside
The backend map
Hover a service and the code panel shows the real Base44 code for it.
A live playground
Run a query against a demo app and get a receipt. You can't break anything.
The switchboard
The course as a row of switches. One flips on for every lesson you finish.
A plain-English glossary
32 backend words on flip cards, with the long version when you want it.
A version for your AI
Copy the whole course as Markdown for Claude, ChatGPT or Cursor.

How it went
It's live and free at whatsbaas.base44.app. Twelve lessons, no account, no code.
If you build on Base44 and "RLS" makes you nervous, start with lesson one. Five minutes from now, you'll get it.
Don't read about it. Run it.
