Start here: describe an app, get a full-stack app
Goal. Sign up and watch Base44 turn one description into a complete, working app — UI, database, auth and hosting included.
Build a conference-room booking app for our office. Staff can see room availability, book a room for a time slot, and the system must prevent double-booking. Admins can add or remove rooms.
Type it in the AI chat. Use Discuss mode first if you want the AI to plan with you (Discuss costs ~0.3 credits and changes nothing); Default mode builds right away.
- 1Go to base44.com and sign up to save your work; the free plan includes free credits.
- 2Describe your app in the AI chat (or switch to Discuss mode to plan first). Base44 designs the UI and wires the database, auth and hosting automatically — you never connect a database or paste a key.
- 3Watch the app appear in the live preview in a few minutes, then refine with follow-up messages or Edit mode (click an element to change it directly — manual edits are free).
You'll see. A complete, working app — front end plus a live backend — generated from one description in minutes.
Cost. Free = 25 message credits + 100 integration credits/month, unlimited apps, with auth, database and analytics included. Building costs ~0.5–4 message credits per change; manual edits and Discuss-mode planning are nearly free — so plan before you spray prompts.
Takeaway. Base44 is all-in-one no-code — the backend exists the moment you describe the app. (You can still export the code later — see Lesson 10.)
