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
