# Experimental-Features

## What is an experimental feature?

Experimental features in FoundationDB are tools or functionalities that developers can use to test new ideas or capabilities within the database system. These features are not fully developed or officially supported yet, so they should not be used for production.

A feature is flagged “production-ready” when either Apple or Snowflake(or any major contributor) is using the feature in production.
