Pipecat vs Deepgram
Pipecat scores 42 to Deepgram's 17 on public evidence for voice & phone agents, and they rank #1 and #3 there. Both are free to start. Numbers below are the same public signals the ranking uses, recomputed nightly — nothing here is sponsored.
Pipecat
Open-source pipeline for voice and multimodal agents, built from swappable frames.
+ The pipeline is explicit, so interruption handling and turn-taking are yours to tune.
− A library, not a dashboard: no call logs or flow editor unless you build them.
Deepgram
A speech-to-text and text-to-speech API built for low-latency streaming at scale.
+ Among the fastest real-time transcription APIs available, with diarization and keyword boosting built in.
− Developer-only; there is no end-user app, and accuracy on heavily accented speech trails Whisper-class models.
