What is the cheapest Synthflow AI alternative?

Rosie, at $0/mo against Synthflow AI's $2500/mo. Both prices read off the vendors' own pages.

Why switch from Synthflow AI?

The gaps buyers hit most: Pricing is not published. The docs state: "Synthflow uses sales-led pricing. Your package is scoped with the Synthflow team based on expected volume, telephony, integrations, and support needs." The only public number is an enterprise floor of $30,000 annually, so a small business cannot price this platform without a sales call. No per-minute rate, included-minute allowance or overage rate is published anywhere on the site or in the docs.
