## Problem After PR #43221 gated `TelemetryTagManager` behind consent, the EU cookie consent banner started reappearing on every page load and when navigating between apps (www, studio, docs). Back in late February we changed `TelemetryTagManager` to only load when the user has accepted consent. This was the right call for GDPR — don't load tracking scripts before consent. But it created a chicken-and-egg problem with how the Usercentrics SDK stores consent. ## What happened When a user clicks Accept, the SDK writes `uc_settings` + `uc_user_interaction: true` to localStorage. Then the GTM script loads (now that consent is granted), and its Usercentrics integration immediately replaces those keys with a compressed `ucString` + `ucData` format — deleting the originals. On the next page load, `UC.init()` only knows how to read `uc_settings`. It can't find it (GTM deleted it), so it treats the user as brand new and shows the banner again. Before #43221, GTM loaded on every page unconditionally, so its integration was already present during `UC.init()` and could interpret the compressed format. Confirmed via production console monitoring — the exact sequence after clicking Accept: ``` setItem("uc_settings", ...) // SDK writes consent setItem("uc_user_interaction", "true") // SDK marks interaction removeItem("uc_settings") // GTM deletes SDK format removeItem("uc_user_interaction") // GTM deletes SDK format setItem("ucString", ...) // GTM writes compressed format setItem("ucData", ...) // GTM writes compressed format ``` ## Changes - Read `ucData` from localStorage **before** `UC.init()` to detect prior consent in the compressed format - If the SDK wants to show the banner but `ucData` shows all services were previously accepted, silently re-accept instead of re-prompting - Added try/catch around the SDK initialization (was fire-and-forget with no error handling, any failure was completely silent) - Error fallback also honors prior `ucData` consent if the SDK fails to initialize ## Testing Can't fully reproduce on staging previews because CSP blocks the GTM script there (so the storage migration never fires). Verified the root cause via production console monitoring with localStorage monkey-patching, and confirmed the `ucData` format persists across page loads on production. Closes FE-2648

How it works
Supabase is a combination of open source tools. We’re building the features of Firebase using enterprise-grade, open source products. If the tools and communities exist, with an MIT, Apache 2, or equivalent open license, we will use and support that tool. If the tool doesn't exist, we build and open source it ourselves. Supabase is not a 1-to-1 mapping of Firebase. Our aim is to give developers a Firebase-like developer experience using open source tools.
Architecture
Supabase is a hosted platform. You can sign up and start using Supabase without installing anything. You can also self-host and develop locally.
- Postgres is an object-relational database system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance.
- Realtime is an Elixir server that allows you to listen to PostgreSQL inserts, updates, and deletes using websockets. Realtime polls Postgres' built-in replication functionality for database changes, converts changes to JSON, then broadcasts the JSON over websockets to authorized clients.
- PostgREST is a web server that turns your PostgreSQL database directly into a RESTful API.
- GoTrue is a JWT-based authentication API that simplifies user sign-ups, logins, and session management in your applications.
- Storage a RESTful API for managing files in S3, with Postgres handling permissions.
- pg_graphql a PostgreSQL extension that exposes a GraphQL API.
- postgres-meta is a RESTful API for managing your Postgres, allowing you to fetch tables, add roles, and run queries, etc.
- Kong is a cloud-native API gateway.
Client libraries
Our approach for client libraries is modular. Each sub-library is a standalone implementation for a single external system. This is one of the ways we support existing tools.
