-One scaling limitation you might face when using Firestore - is the 1 document per second limitation on writes. It can be hard to architect around this issue for users who want to be able to sustain high write loads from a single client. Supabase is built on Postgres which is a tested at scale. Every deployment comes with an instance with PgBouncer, a [Postgres connection pooler perfect for use in Serverless computing](https://supabase.com/docs/guides/database/connecting-to-postgres#connection-pool) environments.

Our most recent results show that [Supabase outperforms Firebase by up to 4x](https://github.com/supabase/benchmarks/issues/8) on number of reads per second, and 3.1x on writes per second.

 ## What are the differences?
 
 ### Core Features
 
-Both solutions run PostgreSQL, but in a time when Developer Experience matters, there is a lot you can do to improve the speed at which developers can build products faster and with less human resource. These are some of the key differences between Heroku Postgres and Supabase in terms of features:
+These are some of the key differences between Heroku Postgres and Supabase in terms of features:
 
 - Supabase is more than just the raw database, it also comes with:
   - [Connection pooling](https://supabase.com/docs/guides/database/connecting-to-postgres#connection-pool) so that you won’t run out of connections in a serverless environment.
   - [Auto-generated APIs](https://supabase.com/docs/guides/api#rest-api-2) based on your schema, so you can communicate with your database directly from the client.
   - [Realtime API](https://supabase.com/docs/reference/dart/subscribe) is useful for when you want to subscribe to changes to your database over websockets.
   - [Auth API](https://supabase.com/auth) can be used to leverage Postgres’s Row Level Security model, and control access to sensitive data on a per user, or per group level.
   - [Functions](https://supabase.com/edge-functions) can be deployed out to the edge directly from the Supabase CLI, which means you can run sensitive business logic or transformations in a serverless fashion.
+    - You can also deploy edge functions to Heroku using their [Dynos](https://www.heroku.com/dynos) runtime in conjunction with something like [Fastly](https://www.fastly.com/).
   - [File Storage](https://supabase.com/storage) is useful for when your app needs to store large files and folders that aren’t suitable for storing within Postgres itself.
   - A spreadsheet-like web interface for building your schemas and inspecting data.
