# Which podcast prefixes does Transistor support?

||| Chartable is closing on December 12, 2024. Transistor will remove the Chartable analytics prefix from user feeds before the closure.

You can use 3rd-party podcast tracking services with your Transistor podcast. These tools can offer additional analytics and monetization opportunities for your podcast. You can enable more than one to stack them together.

To enable these prefixes on your RSS feed, go to your podcast **Settings** page, and select the **Analytics Prefixes** header menu. Check the box for your chosen prefix and click on **Save Changes**.
