## What kind of change does this PR introduce? Feature. Implements [AUTH-1215](https://linear.app/supabase/issue/AUTH-1215/improve-studio-ui-when-send-email-hook-is-active-or-deleted). Follow-up to #45396. ## What is the current behavior? When a send-email hook is configured, email templates are bypassed entirely. Auth passes event metadata to the hook, not rendered HTML. The template list and editor give no indication of this. Deleting the send-email hook silently reverts Auth to using email templates with no warning. For post-cutoff Free plan projects without custom SMTP, this also locks template editing. ## What is the new behavior? ### Admonition when send-email hook is active A new `SendEmailHookActiveAdmonition` is shown on both the template list and individual template editor pages when `HOOK_SEND_EMAIL_ENABLED` and `HOOK_SEND_EMAIL_URI` are set: > **Email templates are not used** > A Send Email hook is active. Event metadata is passed directly to your hook, meaning these templates are bypassed entirely. With a **Manage hook** link to the hooks page. ### AlertDialog for Send Email hook deletion Deleting the Send Email hook now uses a dedicated `DeleteSendEmailHookConfirmationDialog`: - **Always:** "The {default or built-in} email templates will be used to send auth emails." - **Post-cutoff Free plan, no custom SMTP:** adds "Email templates cannot be edited on the Free plan without custom SMTP." The dialog stays open with a loading state while the deletion is in-flight and closes on success. | After | | --- | | <img width="1862" height="880" alt="CleanShot 2026-05-25 at 15 57 41@2x" src="https://github.com/user-attachments/assets/8a441bb2-9112-4b19-bd0b-02c9d1989ec1" /> | | <img width="884" height="578" alt="CleanShot 2026-05-25 at 15 57 21@2x" src="https://github.com/user-attachments/assets/44e5bd79-2bd9-44ee-8f53-5fdaeefd68c6" /> | <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Added a Send Email hook warning in the template editor with “Manage hook” and “Learn more” links. * **UI Improvements** * Refined template editor alerts to reflect when templates are bypassed vs blocked. * Updated hook cards/actions to a dropdown with separate Edit and Delete flows, including documentation links. * **Bug Fixes** * Improved template editor and hook deletion flows to better reflect pending states and current authentication configuration. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: Joshen Lim <joshenlimek@gmail.com> Co-authored-by: Claude Sonnet 4.5 <noreply@anthropic.com> Co-authored-by: Cursor <cursoragent@cursor.com>

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.
