Mert YEREKAPANandkemal d11705ded0 feat(studio): add plan-change panel presentation experiment (#49534)
## What

A/B test for the plan-change side panel
(`/org/_/billing?panel=subscriptionPlan`) — gated behind PostHog flag
`pricingPanelPlanPresentation` (multivariate, 3 arms).

The current panel drops `description`, `preface`, and `footer` from
`shared-data/plans.ts` and uses a much smaller type scale than the www
pricing page, so the two surfaces look unrelated and plan differences
are hard to reason about. This experiment tests whether matching the www
style and surfacing plan gaps improves upgrade conversion.

| Variant | Surface |
| --- | --- |
| `control` | Current panel — no change (baseline cohort, still tracked)
|
| `parity` | www pricing page style: mono uppercase heading,
description, CTA above price, large mono price, preface ("Everything in
the Free Plan, plus:"), 13px features |
| `gaps` | `parity` + gap rows at the bottom showing what the plan is
missing (✗ Daily backups, ✗ Email support, dimmed ✓ 1-day log retention)
|

  • 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.
