Need a reliable alternative to Vapi for your AI calls?
Retell AI delivers a more transparent pricing model, enterprise-grade compliance, and unique call automation features that Vapi doesn't provide.
From advance security features and knowledge base integration to verified numbers and global calling, Retell is built to scale customer conversations with greater reliability and lower costs.
For businesses under pressure to reduce call expenses, improve answer rates, and still deliver human-quality experiences, Retell is the stronger choice compared to Vapi.
Vapi has positioned itself as a developer-friendly platform for creating AI call agents, emphasizing APIs and integrations for custom telephony.
It works well for teams that need to prototype voice applications quickly. However, when it comes to scaling in industries like healthcare, insurance, or logistics, where call reliability, compliance, and cost efficiency directly impact the bottom line, Vapi shows clear limitations.
Retell was designed from the ground up for enterprises that depend on consistent, large-scale call performance.
Financial services, healthcare providers, retail operations, and logistics companies already use Retell to automate thousands of calls every day without sacrificing clarity, uptime, or customer trust.
Where Vapi primarily charges extra for certain core features (like speech-to-text), Retell bundles them into transparent plans while continuously integrating the latest LLMs, including ChatGPT and Anthropic, so customers always benefit from the best possible conversational intelligence.
Vapi AI’s complex platform relies heavily on developer capabilities, making scaling and deployment slow and costly. Retell removes these roadblocks with an intuitive drag-and-drop interface that gets your AI voice agent live in just 3 minutes.
Retell’s Knowledge Base integration lets your agents retrieve accurate answers instantly, even across multi-turn conversations. This ensures sharper, more human-like responses from the very first call. Vapi lacks a comparable feature, which can lead to gaps in call quality and consistency.
Retell AI offers a more transparent pricing model compared to Vapi.
With a flat rate of $0.07/min for an AI voice, Retell eliminates Vapi’s additional fixed platform fees, which can drive up costs. Phone numbers are significantly more affordable at just $2.00/month, while Vapi’s pricing varies.
Retell also includes Speech-to-Text at no extra charge, unlike Vapi’s $0.01/min fee. Plus, Retell provides Verified Phone Numbers to enhance call deliverability and reduce spam risks.
Retell strengthens deliverability with Verified Phone Numbers, significantly reducing the chance of calls being flagged as spam and increasing connection rates. Vapi does not provide this safeguard, putting businesses at greater risk of wasted call volume.
Unlike Vapi’s additional charges for most API integrations, Retell offers transparent, modular pricing, allowing businesses to customize features without unexpected costs.
With Retell, businesses aren’t limited by developer constraints. Our efficient platform ensures you can scale AI voice solutions quickly and effectively.
Retell supports unlimited concurrent call capacity, allowing one agent to manage anything from dozens to thousands of calls in real time. This elasticity is native to the platform, requiring no extra coding or enterprise negotiations. Vapi’s scalability is more restrictive and often gated behind higher-tier plans.
Retell comes with HIPAA, SOC 2 Type 1 & 2, and GDPR compliance across all plans, not just enterprise tiers. Paired with 99.99% uptime and no rate limits, Retell ensures businesses of every size can rely on consistent, compliant, and high-performance operations. Vapi, by contrast, has more limited compliance coverage.
Every Retell plan includes automatic redaction of sensitive personal data (names, addresses, passwords, and more) from transcripts and recordings. This significantly lowers compliance risk and protects customer trust. Vapi does not natively offer this safeguard.
Retell also ensures secure collaboration through role-based access control, letting admins assign permission levels so sensitive data remains protected while developers work efficiently.
Retell AI consistently proves to be the smarter alternative, offering flexible plans, advanced compliance, higher reliability, and built-in innovations that others simply don't match.
While Bland struggles with basic automation, Vapi adds usage fees, and Synthflow limits flexibility, Retell combines it all into one powerful solution. From smarter integrations to post-call analytics, Retell is the trusted choice for growing enterprises.
