Vapi

Vapi is a platform for building advanced voice AI agents, aimed at builders who want to configure agents on their own terms. Its homepage tagline is voice agents for builders, with the promise that teams can build, deploy, and improve voice agents as fast as they ship. Vapi presents itself as one unified platform for all of a team's voice agents, combining orchestration, real time monitoring, and enterprise grade configurability built for scale. Builders configure everything from voice and conversation flow to telephony and integrations, while Vapi handles the infrastructure so a team can move from prompt to production fast, with build, test, and deploy described as taking minutes. Once agents are live, Vapi is built around continuous improvement. Teams can track what is working across every call, surface what is not, and keep improving the experiences that drive their business forward. The homepage reports scale figures of 1 billion calls supported, 2.5 million or more agents launched, and 1 million or more developers, with average latency under 500 milliseconds. A customer quote from Ring on the homepage says that customer went from zero to production in two weeks, that 100 percent of its inbound volume now runs through Vapi, and that customer satisfaction scores have improved while its high bar for support was maintained. For enterprises, Vapi lists a support SLA with contractual uptime and performance guarantees and reserved capacity sized to volume, dedicated deployment support with a dedicated engineer embedded in the team to get live in a week, and scalable infrastructure that can scale to millions of calls. Security and control features listed include SSO, OAuth, and role based access control, AI guardrails built in to prevent model hallucinations and ensure data integrity, and compliance described as SOC 2, HIPAA, and PCI compliant, with 99.9 percent uptime stated for enterprise clients.

Retell AI

Retell AI is an AI voice agent platform for contact centers, in production at more than 4,000 businesses according to its homepage. Its agents answer inbound calls and place outbound calls, qualify leads, book appointments, check order status, and route or transfer callers to a live agent when needed. Retell is built for real contact center demands such as transfers, phone trees, outbound volume, and back end systems that have to work on every call. Features include agentic warm transfers, where the agent briefs the receiving person before connecting the customer, IVR navigation through complex phone trees and extensions, and a mix of deterministic and generative responses so critical steps such as disclosures and verification follow exact requirements while the rest of the conversation stays natural. During a live call, Retell agents can execute custom logic, access real time data, and complete tasks across business systems, from booking appointments to updating records. Persistent memory keeps a running brief on every contact across calls and texts, so returning callers can pick up where they left off. The platform also offers burst concurrency, sentiment analysis, AI quality assurance, live monitoring, and a shared caller history that can sync with an existing CRM or run in Retell CRM. CX teams build agents in a no code studio while developers extend them with APIs and SDKs, and every call is transcribed for review. Retell cites response times around 600 milliseconds and compliance with HIPAA, SOC 2 Type II, GDPR, and ISO 27001, with SSO, personal information redaction, and role based access control. On its pricing page, Retell describes true pay as you go pricing for voice agents at $0.07 to $0.31 per minute depending on the models, voice, and add ons chosen, with enterprise pricing custom, no platform fee, and 20 concurrent calls included. New accounts receive $10 in free credits on signup according to the homepage.

Bland AI

Bland AI, listed as Bland on its own site, is an enterprise voice AI platform for phone agents, built for high stakes and regulated calls where a single misstep can carry serious consequences. Bland says more than 230 regulated companies run on the platform. Its central claim is that it is the only voice AI that runs entirely on its own models and infrastructure, with no third party vendors. On Bland, speech to text, the large language model, and text to speech are all built and run by one team, rather than stitched together from other vendors, so calls never leave to a third party, customer data never trains other models, and outside points of failure are eliminated. Teams use Bland to build end to end agents that handle complex conversations, deploy them on phone, SMS, and web, and connect them to any system. The platform adds full observability so teams can see exactly why an agent made each decision, and a safe improvement loop where changes are tested before they reach live calls. Example call types shown on the homepage include IVR replacement for inbound calls, appointment scheduling, after hours and overflow coverage, verification and data collection, payments and billing, and patient care coordination. Bland also offers a Calls API, a text to speech API with voice cloning from about 10 seconds of audio, and a CLI and MCP server. The homepage lists 200 millisecond response time, 1 million simultaneous calls, and more than 40 supported languages. On its pricing page, Bland charges one per minute rate that covers the language model, speech to text, real time transcription, text to speech, and premium voices, with no token charges and no model provider pass throughs, while telephony is billed separately. The Start plan is $0.14 per minute with no platform fee, and the Build plan is $0.12 per minute plus a $299 per month platform fee, with Enterprise pricing custom. Bland lists SOC 2 Type II, HIPAA, PCI DSS, GDPR, ISO 27001, and FedRAMP credentials on its site.
