Supabase Vercel: How They Work Together in a Lovable App
Supabase and Vercel do not talk to each other directly. Both connect to the same GitHub repo your Lovable app already lives in, one hosts the app, the other stores its data. Here is the real order that happens in.
Your MissionForge guide lives inside your browser
An overlay appears directly on top of Supabase and Lovable. No tab switching, no re-reading docs.
Copy your Project URL
Find the Project URL field below and click the copy icon. We will use this in Lovable’s environment settings.
Stylized preview. The real guide is interactive, not a screenshot.
Deploy the GitHub repo to Vercel first
Sign into Vercel with the same GitHub account you used for Lovable, then choose the repo Lovable already saved your app to. Vercel pulls the code straight from that repo to build and host it.
Go live and confirm the app works
Click deploy, wait the short minute it takes to build, then open the live link to confirm it is the exact app anyone visiting your address would see. A custom domain is optional here, the free Vercel address works on its own.
Connect the same GitHub project to Supabase
Sign into Supabase with that same GitHub account, create an organization, then create your project. This is the step that links Supabase to the GitHub project you already built and deployed, not a separate copy of it.
Create your first table with AI written SQL
Open the SQL Editor and paste in SQL for a simple table, like one for storing a display name and a created_at timestamp per user. You do not write this SQL yourself, an AI like Claude writes it, you paste and run it.
Snag: there is no single switch that links Vercel and Supabase directly
The connection between them is the shared GitHub repo, not a toggle inside either dashboard. If you create a second, unrelated GitHub repo for either step, they stop pointing at the same app.
Where this fits in the bigger picture
You built an app with Lovable, saved it to GitHub, put it live with Vercel, and just gave it a real backend with Supabase. That is the full beginner flow in Build Your First SaaS App For $0.
Why deploy comes before the backend in this flow
Getting a real, live address first means you have something to actually show people while the backend catches up. The app works with placeholder behavior until Supabase is wired in, then the same live address starts saving real data instead of losing it on refresh.
One GitHub repo, two separate dashboards
Vercel and Supabase each connect to the GitHub repo independently, in their own setup step, with their own sign in. Neither one reaches into the other, the repo is just the thing they both happen to point at.

Frequently asked questions
Do Supabase and Vercel connect to each other directly?
No, not directly. Both connect to the same GitHub repo your Lovable app is stored in, Vercel deploys from it and Supabase links its project setup to it.
Which happens first, deploying on Vercel or setting up Supabase?
In this product flow, putting the app live on Vercel happens before building the Supabase backend, it is the second objective in the mission, with Supabase third.
Do I need to write SQL to set up my first Supabase table?
No. You paste SQL that an AI like Claude writes for you into the SQL Editor and run it, you are not expected to write it yourself.
What does the first Supabase table actually store?
A common starting example is a profiles table, storing a display name and a created_at timestamp for each user.
Do I need my own domain name for the Vercel deploy?
No, that step is optional. Your app gets a free working Vercel address by default, a custom domain is something you can add later if you already own one.
Deploy before you build the backend
Following the real product order, getting a live Vercel address first, then wiring up Supabase, means you always have something real to check your work against.
Keep both connected to the same GitHub repo
Vercel and Supabase should both point at the one repo Lovable created, not separate copies, or the app you see live will not match the backend you built.
Let AI write your SQL
Paste the SQL an AI like Claude gives you into the Supabase SQL Editor rather than writing table definitions by hand.
Why people drop off before they finish
You're not the problem. The format is. Here's what changes when you switch to an interactive mission.
- ✕Pause, rewind, pause again, repeatedly
- ✕The UI has changed since recording
- ✕No feedback when you complete a step
- ✕Lose context every time you switch tabs
- ✓Live overlay, no tab switching ever
- ✓Always current: guides track the real UI
- ✓Instant confirmation at every step
- ✓Full context stays open in your browser
