Pros
  • Was well-regarded for voice cloning and API pricing before shutdown
  • Large historical user base (40,000+ accounts) before Meta's acquisition
  • Proven at serious scale — Vapi reports 1B+ calls handled and 99.9% uptime for enterprise customers
  • Bring-your-own-provider flexibility avoids lock-in to a single STT/LLM/TTS vendor
  • Deep telephony integrations (Twilio, Telnyx, Vonage) plus free native US phone numbers
  • No long-term contract required on the self-serve Build plan
  • Strong enterprise trust signals — customers include Amazon Ring, Intuit, ServiceTitan and New York Life
Cons
  • Fully shut down as of December 31, 2025 following Meta's acquisition of the PlayAI team
  • All accounts, voice clones and audio were permanently deleted with no migration path
  • No longer available to sign up for or use in any form
  • The advertised $0.05/min rate is only the Vapi platform fee — real all-in cost with STT+LLM+TTS+telephony typically lands around $0.30+/min
  • No self-service cancellation — removing a payment method or closing an account requires emailing support or posting on Discord
  • Marketed as accessible, but building a production-grade agent still requires real engineering effort
  • International phone numbers are not free and cost more than US numbers
  • Independent reviews report sparse documentation and slow support response on the self-serve tier

Read the full PlayHT review

PlayHT (PlayAI) was an AI voice generator offering text-to-speech, voice cloning and a developer API, historically priced around $39/month (Creator) and $99/month (Pro) with a limited free tier. Meta acquired the PlayAI team in July 2025, absorbing it into its Superintelligence Labs division; the API went offline within weeks, and the platform was permanently shut down on December 31, 2025, with all accounts, voice clones and audio deleted with no migration path. It no longer operates as a product — this listing exists so readers searching for a PlayHT alternative land on accurate, current information rather than stale marketing copy.

Read the full Vapi review

Vapi is a developer-first voice AI platform for building, testing and deploying AI phone agents in production. Agents are assembled from a voice, an LLM, and a speech-to-text engine — Vapi supports bringing your own provider API keys or paying providers at cost through the platform — wired into a real-time pipeline built for sub-500ms latency and enterprise call volume. It ships native US phone numbers plus SIP/telephony integration with Twilio, Telnyx and Vonage, real-time call monitoring and post-call analytics, webhooks and function calling for connecting agents to external tools, and AI guardrails to reduce hallucinations. Vapi reports handling over 1 billion calls with 99.9% uptime for enterprise customers, 2.5M+ agents launched and 750K+ developers on the platform, with customers including Amazon Ring, Intuit, ServiceTitan and New York Life. The self-serve Build plan is usage-based with no monthly minimum; the Scale plan is a custom annual contract for enterprises needing committed volume, SOC 2/HIPAA/PCI compliance, SSO, RBAC and a dedicated account team.
