Dasha

Dasha is a developer platform for building voice and text AI agents that run over telephony, WebRTC and text channels. Developers define agents through a REST API and can move to full control of conversation flow when they need complex multi turn workflows and predictable behavior, which lets teams start quickly and still customize agents for demanding production deployments. It is aimed at developers and companies shipping voice AI at scale, including those outgrowing hosted voice APIs. Dasha emphasizes response speed and cites its ranking on the voicebenchmark.ai latency comparison. The platform supports more than 10,000 concurrent calls, over 30 languages with switching between languages in the middle of a call, and any large language model, including GPT, Claude and Gemini, so customers are not tied to one model vendor. It also publishes machine readable endpoints so AI agents can query information about the product directly. Pricing is published in two tiers. Developer is free and includes 1,000 minutes, one concurrent call, full API access and email support, with no credit card required. Growth starts at $0.08 per minute and adds unlimited concurrent calls, up to 1,000 per agent or more on request, a 99.99 percent uptime target, priority support through a private channel, and volume and committed usage discounts. The Growth rate covers everything except VoIP and LLM token costs, which are billed separately. All plans bill by the second with no minimum call duration and no charge for call attempts that do not connect.
