## What kind of change does this PR introduce? Studio UI consistency refactor. ## What is the current behaviour? Several Studio comboboxes still build their triggers from `Button` and supply their own double-chevron icon. This duplicates trigger styling and allows these controls to drift from selects and other comboboxes. ## What is the new behaviour? - Migrates the PITR timezone, AWS region, and account timezone controls to `ComboboxTrigger` - Migrates the shared `SchemaSelector` and `FunctionSelector`, updating their Studio callsites together - Preserves the globe icon in both timezone controls - Exposes the correct combobox role and open state through the shared trigger - Tightens the tiny schema selector end padding so its chevron aligns with adjacent controls - Leaves organisation and project context switchers unchanged | Before | After | | --- | --- | | <img width="504" height="490" alt="CleanShot 2026-09-09 at 13 56 56@2x" src="https://github.com/user-attachments/assets/117a9169-88bf-4f9e-8302-9df9b911a307" /> | <img width="496" height="512" alt="CleanShot 2026-09-09 at 11 31 26@2x" src="https://github.com/user-attachments/assets/bc98cded-2723-4d20-9d8c-49630ea018af" /> | | <img width="1250" height="394" alt="CleanShot 2026-09-09 at 13 58 34@2x" src="https://github.com/user-attachments/assets/9106f924-88fd-40d4-88e3-8d0ddbb61d12" /> | <img width="1246" height="376" alt="CleanShot 2026-09-09 at 13 58 09@2x" src="https://github.com/user-attachments/assets/7894a254-f6f9-40bb-a312-9f1a5079f096" /> | ## To test On the [Studio preview](https://studio-staging-git-dnywh-choremigrate-combobox-680102-supabase.vercel.app): 1. Open **Database > Tables** and use the schema selector above the table. It should use a single down chevron, open normally, and update the selected schema. 2. Open **Authentication > Hooks > Add hook**, then select **Postgres** as the hook type. The **Postgres schema** and **Postgres function** selectors should use a single down chevron and continue to open and select normally. The PITR, AWS region, and account timezone callsites require the relevant plan, integration, or feature flag. When available, their triggers should use the same single down chevron, and both timezone controls should retain the globe icon. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **UI Improvements** * Standardized timezone, AWS region, database backup, function, and schema selectors with a consistent combobox interface. * Added clear visual feedback for open and closed selector states. * Preserved contextual icons and labels, including globe icons for timezone selections. * Improved accessibility with appropriate combobox semantics, accessible names, and state information. * Timezone settings are now available without an optional feature flag. * **Tests** * Updated end-to-end coverage for the standardized combobox controls. * Added coverage confirming schema selectors expose the selected schema as an accessible name. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: Joshen Lim <joshenlimek@gmail.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.
- Envoy is a cloud-native, high-performance edge and service proxy.
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.
