Danny WhiteandJoshen Lim 69f3c43118 fix(studio): close Vercel create popup on cancel (#48371)
## What kind of change does this PR introduce?

Bug fix / UX polish.

## What is the current behavior?

Cancel on the Vercel create interstitial redirects to Vercel’s `next`
URL. That finishes the install flow and shows “Completing installation…”
/ “Installation complete”, even though the user cancelled. The Deploy
Button job still proceeds and fails. The button was also labelled
“Return to Vercel”, which read like an alternate success path.

## What is the new behavior?

- _Return to Vercel_ button now labelled **Cancel**
- **Cancel** closes the popup via `window.close()` (same honest abort as
manually closing the window)
- If the browser blocks programmatic close, Cancel is replaced by muted
fallback copy: “Close window to cancel” (`role="status"` /
`aria-live="polite"`)
- Cancel is left-aligned with `justify-between` when there’s no
additional-costs block; with costs, both actions stay on the right
- Removes the free-limit hint line about returning to Vercel (Cancel
makes that self-evident)
- Success path is unchanged: after create, we still redirect via `next`
- `/new` Cancel still navigates into Studio (`cancelAction: 'studio'`).
This is unchanged behaviour

## Additional context

Follow-up to #48311. Vercel’s `next` URL has no documented cancel/abort
status, so closing the popup is the correct escape hatch.

### To test

Full Deploy Button popup cancel can’t be verified on prod until this
merges. Locally:

1. Open Studio on this branch.
2. In `ProjectCreationFooter.tsx`, temporarily force the fallback:
   ```ts
   const [showCloseWindowHint, setShowCloseWindowHint] = useState(true)
   ```
3. Load create-project UI:
- Free org / no costs: Confirm Cancel is left, Create is right
(`justify-between`). With the forced hint, Cancel is replaced by “Close
window to cancel”.
- Paid org with additional costs: Confirm costs on the left; hint/Create
on the right.
4. Revert `useState` to `false`.
5. Optional: open a Vercel create interstitial URL in a normal tab (not
a popup), click Cancel. `window.close()` fails and the hint should
replace Cancel after ~100ms.
6. On `/new/[slug]`, Confirm Cancel still returns to the Studio
dashboard (not close-window).

Supabase Studio

A dashboard for managing your self-hosted Supabase project, and used on our hosted platform. Built with:

What's included

Studio is designed to work with existing deployments - either the local hosted, docker setup, or our CLI. It is not intended for managing the deployment and administration of projects - that's out of scope.

As such, the features exposed on Studio for existing deployments are limited to those which manage your database:

  • Table & SQL editors
    • Saved queries are unavailable
  • Database management
    • Policies, roles, extensions, replication
  • API documentation

Managing Project Settings

Project settings are managed outside of the Dashboard. If you use docker compose, you should manage the settings in your docker-compose file. If you're deploying Supabase to your own cloud, you should store your secrets and env vars in a vault or secrets manager.

How to contribute?

  • Branch from master and name your branches with the following structure
    • {type}/{branch_name}
      • Type: chore | fix | feature
      • The branch name is arbitrary — just make sure it summarizes the work.
  • When you send a PR to master, it will automatically tag members of the frontend team for review.
  • Review the main contributing guide to help test your feature before sending a PR.
  • The Dashboard is under active development. You should run git pull frequently to make sure you're up to date.

Developer Quickstart

Note

Supabase internal use: To develop on Studio locally with the backend services, see the instructions in the internal infrastructure repo.

# You'll need to be on Node v22
# in /studio

## For external contributors
pnpm install # install dependencies
pnpm run dev # start dev server

## For internal contributors
## First clone the private supabase/platform repo and follow instructions for setting up mise
mise studio  # Run from supabase/platform alongside `mise infra`

## For all
pnpm run test # run tests
pnpm run test -- --watch # run tests in watch mode

Running within a self-hosted environment

Follow the self-hosting guide to get started.

cd ..
cd docker
docker compose -f docker-compose.yml -f ./dev/docker-compose.dev.yml up

Once you've got that set up, update .env in the studio folder with the corresponding values.

POSTGRES_PASSWORD=
SUPABASE_ANON_KEY=
SUPABASE_SERVICE_KEY=

Then run the following commands to install dependencies and start the dashboard.

npm install
npm run dev

If you would like to configure different defaults for "Default Organization" and "Default Project", you will need to update the .env in the studio folder with the corresponding values.

DEFAULT_ORGANIZATION_NAME=
DEFAULT_PROJECT_NAME=
