Synthflow Alternative $29/mo vs $99/mo, No Minute Caps
Synthflow dropped its $29 plan. RhythmiqCX kept it and added WhatsApp, web chat, and no minute limits.
Why Teams Are Looking for a Synthflow Alternative
Synthflow used to offer a $29/month entry tier it removed it. Their current entry plan starts at $99/month and comes with a monthly minute cap. That's a 3.4× price increase for the same core use case: an AI voice agent that answers customer calls. On top of that, Synthflow is voice-only there's no WhatsApp channel, no web chat widget, and no omnichannel inbox. RhythmiqCX fills exactly that gap: the same AI voice capabilities, still at $29/month flat, with web chat and WhatsApp included in the same dashboard.
