Vapi alternative for agencies
Choose the operating layer, not just the voice runtime
VoiceForge is for agencies that sell answering service and AI receptionist outcomes — not minutes. Vapi is a developer voice API; VoiceForge is the governed operating layer that turns a client brief into a reviewable, testable deployment.
A reviewable contract instead of scattered code
The Agent Spec carries goals, call flow, tools, guardrails, compliance policy and handoff behavior in one Zod-validated JSON diff. The provider adapter translates that contract for the runtime.
Test the call before attaching telephony
Run a full browser test with transcript, events and outcome. Publish only the version you already reviewed — so you do not learn about a broken transfer from a real caller.
Deliver a workspace to each client
Separate agency and client workspaces scope agents, knowledge, calls and analytics correctly. Apply logo and color branding without forking the platform.
Put compliance in the execution path
Outbound calls require a permitted purpose and a passing check across consent, DNC/DND, opt-out, calling windows and AI disclosure. Cold sales and regulated advice are blocked by default.
When VoiceForge is not the fit
Choose a direct voice API when you want to build and operate the entire control plane. Choose VoiceForge when governed, multi-client delivery is the work you do not want to rebuild.
Frequently asked questions
- Is VoiceForge a replacement for Vapi?
- For agencies, usually yes. Vapi is a developer voice API: you code and operate the control plane yourself. VoiceForge is the governed operating layer above the runtime — versioned Agent Spec JSON, isolated white-label workspaces and a compliance gate on every outbound call. If you want to own the control plane code, a direct API remains the better fit.
- How does pricing compare to Vapi?
- Vapi charges per-minute plus telephony; VoiceForge charges flat $99/$299/$999 per month covering spec generation, browser test calls, workspaces and analytics. Telephony is provider-neutral (OpenAI Realtime or in-house Azure pipeline) so agencies can price answering service retainers with predictable margin.
- Can I test an agent before it takes real calls?
- Yes. Every agent runs a browser test call with live transcript, event stream, tool activity and outcome before any phone number is attached. Publishing is a deliberate, reviewable step on a versioned spec — not a dashboard toggle with silent side effects.
- What voice runtimes does VoiceForge run on?
- OpenAI Realtime on paid plans plus an in-house pipeline (Azure Speech STT → Azure OpenAI → Azure Speech TTS) for HIPAA-eligible workloads when Azure BAAs, PHI handling and provider eligibility have been verified per deployment (LiveKit/Supabase/Twilio/Vobiz require separate review). Agents are provider-neutral specs so a deployment can move runtimes without rebuilding.
- Does VoiceForge handle AI receptionist and answering service use cases?
- Yes. Inbound reception, after-hours coverage, missed-call callback and appointment booking are first-class templates. Each client gets an isolated workspace so answering service calls, transcripts and analytics never bleed between clients.
