Decision brief

Patter is an open-source SDK enabling voice AI integration in applications via telecommunication services such as Twilio, Telnyx, and Plivo, supporting Python and TypeScript.

Good fit when

  • When you prefer to have full control over the technology stack of your voice-based AI solution, Patter lets builders own their AI agent's entire infrastructure.
  • If you are looking for an open-source alternative to Vapi/Retell which supports both Python and TypeScript, Patter fits this specific requirement.

Avoid when

  • Avoid Patter if your project requires support from telecommunication services not covered by Twilio, Telnyx, or Plivo.
  • Do not use Patter if the open-source nature of the SDK is a concern for commercial use, as its license may pose issues in certain enterprise contexts.
