Provider-Agnostic Backend

[eldinmiller]

Problem

BluePLM is currently tightly coupled to Supabase services. Currently, there are ~557 direct Supabase client calls in the codebase. This vendor-locks the backend to use Supabase (which is not a big deal bc it is open-source).

Goal

Enable BluePLM deployments with customer-owned infrastructure while preserving real-time collaboration features.

Component	Supabase (default)	Alternative
Auth	Supabase Auth	OIDC (Keycloak, Auth0, Okta, Azure AD)
Database	Supabase Postgres	Standard PostgreSQL 14+
Storage	Supabase Storage	S3-compatible (MinIO, AWS S3, GCS)
Realtime	Supabase Realtime	WebSocket server + pg_notify

In src/components/shared/Screens/SetupScreen.tsx (around line 112)

So you can use your own self-hosted Supabase by entering a full base URL (e.g. https://supabase.fritz.box) in the Project ID field. Otherwise the input is treated as a Supabase Cloud project id and mapped to https://<project>.supabase.co.

it worxs ™ 😉 with 3.10 and some earlier versions.
