Vapi Review 2026: Composer, Evals & Vapi Voices

In 2026, Vapi significantly evolved its platform, securing a $50M Series B funding at a $500M valuation, and notably being chosen by Amazon Ring over 40 competitors for its voice AI capabilities. The company introduced a suite of new features, including Composer, a natural-language agent builder that expands Vapi's usability beyond engineers, and advanced monitoring tools for production observability. Vapi's offerings include Assistants and Squads for voice agent orchestration, while de-emphasizing Workflows. Integrations with platforms like GPT-5 and OpenAI Realtime highlight its commitment to maintaining an adaptable, open architecture. Vapi's pricing strategy remains usage-based, with native observability tools that provide detailed monitoring but are primarily beneficial for those committed to the Vapi ecosystem. The platform targets B2B-grade voice agents, offering flexibility and compliance options, though it faces competition from other platforms for specific low-latency or no-code needs.
