Which one should you evaluate first?
If your priority is the most verifiable trust profile today, start with Pipecat. It has the stronger current HVTrust score and ranks higher in Voice & Conversational. If your use case depends on a specific runtime, language, license, or integration model, use the individual profiles rather than the headline score alone.
For production use, the practical checklist is: inspect the security policy, confirm package provenance or release signing where available, review recent maintenance cadence, and compare the exact trust breakdown. HVTracker is meant to reduce the first-pass research burden, not replace your own risk review.
