## What it is
|
|
|
|
Supabase is an open source Firebase alternative. We are a service to:
|
|
|
|
- Listen to database changes.
|
|
- Query your tables, including filtering, pagination, and deeply nested relationships (like GraphQL).
|
|
- Create, update, and delete rows.
|
|
- Manage your users and their permissions.
|
|
- Interact with your database using a simple UI.
|
|
|
|
## What it isn't
|
|
|
|
Supabase is not a 1-to-1 mapping of Firebase. While we are building many of the features that Firebase offers, we are not going about it the same way.
|
|
|
|
Our technological choices are quite different to Firebase. Everything we use is open source. Wherever possible, we use and support existing tools in the ecosystem, rather than developing from scratch.
|
|
|
|
Most notably, we use Postgres rather than a NoSQL store. This was a deliberate choice. We believe that no other database on the market offers the scalability and functionality required to legitimately compete with Firebase.
|
|
|
|
## How it works
|
|
|
|
At its core, Supabase is a suite of open source tools, stitched together to build a seamless developer experience:
|
|
|
|
|
|
|
|
- [PostgreSQL](https://www.postgresql.org/) 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](https://github.com/supabase/realtime) is an Elixir server that allows you to listen to PostgreSQL inserts, updates, and deletes using WebSockets. Supabase listens to Postgres' built-in replication functionality, converts the replication byte stream into JSON, then broadcasts the JSON over WebSockets.
|
|
- [PostgREST](http://postgrest.org/) is a web server that turns your PostgreSQL database directly into a RESTful API.
|
|
- [postgres-meta](https://github.com/supabase/postgres-meta) is a RESTful API for managing your Postgres, allowing you to fetch tables, add roles, and run queries etc.
|
|
- [GoTrue](https://github.com/netlify/gotrue) is an SWT-based API for managing users and issuing SWT tokens.
|
|
- [Kong](https://github.com/Kong/kong) is a cloud-native API gateway.
