# Redis® API Compatibility: supported commands, modules, and protocols

<Note>
  Upstash supports both native Redis TCP and HTTPS REST.
</Note>

Upstash supports Redis client protocol up to version `8.2`. We are also gradually adding changes introduced in later versions.

SDK command references may cover a smaller set of typed helpers.
For example, see the [TypeScript SDK command reference](/redis/sdks/ts/commands/overview) for the commands documented in `@upstash/redis`.

Most unsupported items are on our roadmap. If you need a feature that we do not support, email [support@upstash.com](mailto:support@upstash.com) so we can let you know when we plan to support it.
