Key features

Cartesia: Sonic state-space TTS built for very low time-to-first-audio, the specific problem Cartesia was founded on; First-party STT (Ink) alongside first-party TTS, so one vendor covers both legs of the pipeline; Voice agents at $0.06/min with optional $0.014/min first-party telephony, cheaper than bolting on a third-party carrier; Optional Zero Data Retention plus SOC 2 Type II, HIPAA, PCI-DSS (service level provider) and GDPR compliance; Entry paid tier at $5/month is the lowest in this set, so the step off free is nearly free

Pipecat Cloud: Managed hosting for Pipecat, the widely used open-source voice-agent framework, so there is a credible exit path to self-hosting; Unlimited concurrency is advertised, though the page directs you to contact Daily rather than publishing a self-serve ceiling — still notable in a category where concurrency is the standard upsell lever; Reserved instances cut the compute rate about 20x for predictable steady-state traffic; Three container sizes priced linearly, so a heavier agent costs proportionally rather than forcing a plan change; Daily WebRTC 1:1 voice transport is free, so a browser-based agent pays compute only; Krisp VIVA noise suppression included to 10,000 minutes/month
