The honest brief

Pipecat

Vendor-neutral, it wires 40+ STT, LLM, and TTS services into one low-latency pipeline — unlike single-vendor voice-agent platforms.

  • Self-hostable, no vendor lock-in
  • Mix and match any STT, LLM, and TTS
  • Real-time listen, speak, and see
  • Client SDKs across web/mobile/embedded
  • Optional managed Pipecat Cloud
  • Python framework, not a no-code tool
  • You wire and pay for each AI service
  • Tuning latency needs real expertise
  • Smaller ecosystem than hosted rivals

Retell AI

Bring your own LLM behind the voice agent, so it isn't locked to a single model like most all-in-one voice platforms.

  • Inbound and outbound call handling
  • SIP/Twilio telephony built in
  • Low-latency turn-taking model
  • No-code builder plus API
  • Per-minute costs stack with LLM/TTS
  • Voice quality depends on chosen vendors
  • Cloud-only, no self-host
