Danny White ed692f6905 feat(select): schedule livestream banners (#51006)
## Problem

The Select banners on www and Studio still promote attendance. They need
to keep serving the waitlist until the event, promote the livestream
during the requested window, and disappear after the event.

## Solution

Use a shared three-phase clock: existing promotion before 8:00am PT on 2
October, livestream promotion from 8:00am to 5:30pm PT, and no banner
afterwards. Both livestream CTAs lead to `select.supabase.com`, where
viewers can choose a stage. Separate dismissal keys let someone who
dismissed the earlier promotion see the livestream. Open pages set a
timer for the next boundary and recheck on visibility, focus, or page
restore.

## Review instructions

1. Open the [www
homepage](https://zone-www-dot-com-git-dnywh-select-2026-livestre-93dab1-supabase.vercel.app/)
and a [hosted Studio
dashboard](https://studio-staging-git-dnywh-select-2026-livestream-05b822-supabase.vercel.app/)
in separate tabs. If the Privacy Policy update card is in front in
Studio, close it (only) to reveal the Select banner.
2. In each tab's DevTools console, paste this helper:
   ```js
   window.selectRealNow = Date.now
   window.showSelectAt = (iso) => {
     Date.now = () => new Date(iso).getTime()
     window.dispatchEvent(new Event('focus'))
   }
   ```
3. Run `showSelectAt('2026-10-02T07:59:00-07:00')`: both banners keep
the existing “Apply to attend” CTA.
4. Run `showSelectAt('2026-10-02T08:00:00-07:00')`: www shows “Supabase
Select 2026” and “Watch the livestream”; Studio shows the same title,
the description “Keynote, main stage, and build stage, streamed all
day.” and “Watch livestream”. Both CTAs link to
`https://select.supabase.com/`.
5. Run `showSelectAt('2026-10-02T17:30:00-07:00')`: neither banner is
visible. Restore the clock with `Date.now = window.selectRealNow;
window.dispatchEvent(new Event('focus'))`.

The console clock override affects only the current tab and is lost on
reload.

Community & Support

  • Community Forum. Best for: help with building, discussion about database best practices.
  • GitHub Issues. Best for: bugs and errors you encounter using Supabase.
  • Email Support. Best for: problems with your database or infrastructure.
  • Discord. Best for: sharing your applications and hanging out with the community.

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.

Architecture

  • 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.
