Dasha vs Vapi

Vapi has a no-code agent builder and partial white-label sub-accounts for agencies, directly matching both requirements of the use case. Dasha is API-first with no evidence of a no-code builder or white-label capability. Vapi also includes native integrations with GHL, Zapier, and Make, which are commonly used in agency workflows. These differentiators decisively favor Vapi for a no-code agency deploy and resale scenario.

Both tools are API-first (facts aa673710 and 96c19528), but Vapi offers bring-your-own LLM, bring-your-own TTS voice, and LLM/TTS cost passthrough, giving engineering teams direct control over every pipeline component. Vapi also includes a simulation and testing suite and native SIP trunking, both of which matter for custom pipeline construction. Dasha bundles LLM and TTS without passthrough, limiting component-level substitution. Vapi's higher base concurrency of 10 calls versus Dasha's 1 further supports pipeline scale testing.

For ecommerce support flows, Vapi offers a broader feature set directly relevant to the use case. It includes native outbound campaigns, warm transfer to human, a built-in knowledge base, a no-code agent builder, DTMF/IVR navigation, and native integrations with GHL, Zapier, Make, Google Calendar, and Twilio, all vendor-confirmed. Base price is $0.05/min versus Dasha's $0.08/min, and Vapi includes 10 concurrent calls at base versus Dasha's 1. These features collectively support order lookup, escalation, and campaign workflows that ecommerce teams need.

For HIPAA-bound healthcare workflows, the critical requirement is a HIPAA BAA. Vapi explicitly offers a HIPAA BAA as a paid addon, meaning it is available and contractually obtainable. No corresponding HIPAA BAA fact exists for Dasha in the provided fact set, making Vapi the only tool with confirmed HIPAA coverage. Vapi also adds recording consent tooling and GDPR tooling, reinforcing its compliance posture. The margin is narrow because the BAA is an addon cost rather than included, but Vapi is decisively the only option with a confirmed compliance path.

Vapi offers native outbound campaign support, 10 concurrent calls on the base plan versus Dasha's 1, and a lower base price of $0.05/min versus Dasha's $0.08/min. For outbound sales volume, concurrency is critical, and Vapi starts 10x higher. Vapi also includes native SIP trunking, warm transfer to human, and GHL/Zapier/Make integrations that are standard in sales workflows. Dasha's concurrency limit of 1 and higher per-minute cost make it clearly less suited for call-center scale campaigns.

For an SMB receptionist and booking use case, Vapi wins on nearly every practical dimension. Its base price of $0.05/min is lower than Dasha's $0.08/min. Vapi includes 10 concurrent calls on the base plan versus Dasha's 1 call, which matters for after-hours coverage when multiple callers may arrive simultaneously. Vapi also offers native outbound campaigns, warm transfer to human, built-in knowledge base, no-code agent builder, Google Calendar integration, and a $0/mo platform fee, all directly relevant to receptionist and booking workflows. Dasha's single concurrent line limit alone would be a serious bottleneck for a busy SMB.
