Is there a free or open-source alternative to Pipecat?

How are these Pipecat alternatives ranked?

Every product in the voice agents category is a candidate. Open-source alternatives are ranked by maintained adoption — GitHub stars plus recent commit activity — so you see what's genuinely used, not abandoned.
