a3e71ba888 feat(sso): add IdP-initiated login support with optional domains (#44033)
Implements comprehensive IdP-initiated login flow support, enabling
organizations to configure SSO without email domains and support
multiple SAML apps under the same domain (e.g., Dev/Staging/Prod
environments).

- Add "Enable SP-initiated login" toggle to SSOConfig.tsx
  - IdP-initiated flow is now always available (default)
  - SP-initiated flow is opt-in with domain requirement
  - Clear in-UI documentation explaining both flows
- Make domains optional (only required when SP-initiated enabled)
- Add form validation: domains required only if SP-initiated is ON
- Fix org-switching bug: form now resets when switching organizations
  - Add organization.slug to useEffect dependencies
  - Prevent stale SSO config data from previous org being displayed

- **IdP-initiated flow**: Users start login from identity provider
dashboard
  - No domain configuration required
  - Enables multiple SAML apps per domain
  - Recommended default for enterprises
- **SP-initiated flow**: Users start login at supabase.com (opt-in)
  - Requires email domain configuration
  - Maintains backward compatibility
- **Both flows**: Can be enabled simultaneously for flexible access

- Organizations can now create separate SSO providers for
Dev/Staging/Prod
  - Each environment = separate SAML app in IdP
  - All using same email domain (e.g., company.com)
  - Users access via different IdP app tiles
  - No domain conflicts or subdomain requirements

- Add 4 pages to SSO sidebar menu in NavigationMenu.constants.ts:
  - Understanding Login Flows (existing, now visible)
  - Choosing a Login Flow (existing, now visible)
  - Multiple SSO Providers (NEW comprehensive guide)
  - Testing and Best Practices (existing, now visible)

Create comprehensive guide covering:
- Multi-environment patterns (Dev/Staging/Prod with same domain)
- Team separation, migration, and acquisition scenarios
- Step-by-step setup for domainless providers
- User access management and IDP app assignment strategies
- Configuration synchronization and best practices
- Troubleshooting common multi-provider issues

Major expansion of testing-best-practices.mdx:
- Fix outdated assumptions (domains no longer always required)
- Add comprehensive login flow testing section:
  - IdP-initiated testing (no domains)
  - SP-initiated testing (with domains)
  - Domainless provider testing (multi-environment pattern)
- Enhance auto-join testing with 8 detailed test phases:
  - Idempotency testing (no duplicate memberships)
  - Domainless configuration testing
  - Re-enablement testing (works on every login)
- Add SSO account restrictions testing section
- Add safe provider deletion testing with 4 test scenarios
- Reorganize final checklist into 6 categorized sections

Update azure.mdx, gsuite.mdx, okta.mdx:
- Remove all "(coming soon)" references
- Add guidance recommending IdP-initiated for multi-environment setups
- Clarify domains are optional for IdP-initiated flow
- Link to new Multiple SSO Providers guide

**Domain Handling:**
- Domains now optional in SSO provider configuration
- Backend: `z.array(...).optional().default([])`
- UI: Domains only required when SP-initiated toggle is ON
- Empty array sent to API when SP-initiated disabled

**Login Flow Logic:**
- IdP-initiated: Always available, uses SAML assertion directly
- SP-initiated: Requires domain lookup, opt-in only
- Both flows can coexist with same SSO provider

**Multi-Provider Support:**
- Each provider has unique ACS URL
- No domain conflicts (IdP-initiated doesn't check domains)
- Enables unlimited providers per email domain

- **Simplifies SSO setup**: No domain configuration needed by default
- **Enables multi-environment**: Dev/Staging/Prod under same domain
- **Improves UX**: One-click login from IdP dashboard
- **Maintains compatibility**: SP-initiated still available as opt-in
- **Better documentation**: Comprehensive guides for all scenarios

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 contributing checklists 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 v20
# 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=
