Decision brief

fastrtc is a Python library offering real-time communication capabilities such as pause detection and text-to-speech.

Good fit when

Use fastrtc for projects that require pause detection in audio streams as it provides the specific ReplyOnPause feature.
Select fastrtc if your project needs integrated text-to-speech functionality because it includes dedicated text-to-speech capabilities after installing extras.

Avoid when

Avoid fastrtc when the project requires real-time communication features not covered by its pause detection or text-to-speech services.
Do not use fastrtc if support for multiple languages beyond what Python and this library's built-in features provide is necessary.
