# TeXML and TwiML Compatibility

> Side-by-side comparison of TeXML and TwiML verb and noun support, helping you migrate Twilio call control instructions to Telnyx with minimal changes.

TeXML services was created to allow the easy migration from Twilio to Telnyx, allowing you to use the same verbs and nouns in both platforms.

This page provides a comparison of verb support between TeXML and TwiML, helping you understand which features are available in each platform.
