Audact vs Vapi.
Article 50 in force since 2 Aug 2026
Vapi is a flexible US developer-infrastructure layer with no EU residency and no Article 50 — you assemble the rest, including agency tooling, through third-party wrappers. Audact is EU-hosted in Frankfurt and ships the proof Vapi leaves to you: Article 50 enforced at runtime, a tamper-evident receipt for every call, brand governance before the AI speaks, and native white-label with sub-accounts. Nothing to wire together. Side by side:
Audact is EU-hosted in Frankfurt and moving to a fully EU-native stack; Retell/Vapi are US-hosted.

When Vapi is the right answer
You have a developer team that wants to compose its own STT/TTS/LLM stack via BYOK, you’re comfortable wiring agency tooling through third-party wrappers, and EU regulatory exposure isn’t the binding constraint.
When Audact is the right answer
You serve EU end-clients, you need a signed, tamper-evident receipt for every call, and you want native white-label, sub-accounts and Stripe Connect built in — not assembled. All-in pricing, no key-juggling, no wrapper-tax.
