Comparison · honest data

Anuvo is a Vapi alternative that answers in 355 ms self-hosted — no per-minute fee, no audio leaving your network.

If you've outgrown a cloud voice platform, or your compliance team vetoed one, Anuvo is the alternative: the same class of voice agent, but 350 ms hosted or 355 ms entirely inside your infrastructure.

We're not going to pretend Vapi is bad — it isn't. It's a capable cloud voice platform with a mature ecosystem. This page is the honest comparison: where Vapi wins, where Anuvo wins, and how to decide in one afternoon.

Side by side

Anuvo vs Vapi, feature by feature

Columns are honest: Anuvo Cloud is our hosted edition, Anuvo Resident is our differentiator. Vapi figures reflect its published cloud model.

When each wins

How to decide, in one afternoon

Choose a cloud voice platform (Vapi or Anuvo Cloud) when…

  • You want the fastest path to a live agent and don't want to run infrastructure.
  • Your data is not regulated, or your regulator accepts a hosted model.
  • You need a specific third-party integration only one ecosystem has.

Choose Anuvo Resident when…

  • Your compliance policy forbids patient or client audio leaving your network — hospitals, labs, legal.
  • You want a fixed cost with no per-minute fee, and no vendor repricing risk.
  • You want measured sub-400 ms latency with the method published.
  • You want zero third-party model dependency and full audit control.
The decision rule: if "where does the audio go?" is a question you must answer in a procurement document, Resident is the category. If you just want calls answered this week, Cloud gets you there in days. The architecture planner recommends from your actual volume and compliance answers.

Migration

Moving from Vapi to Anuvo

Your conversational design transfers more than you'd think: intents, knowledge base and escalation rules map onto Anuvo agents; integrations move to REST and webhooks.

1 · Rebuild the agent

Languages, knowledge base, barge-in and escalation map 1:1 onto Anuvo's agent configuration. See the agent API.

2 · Re-point the number

PSTN forwarding or SIP trunk — your number stays yours. On Resident, your PBX routes calls in-network.

3 · Verify with the benchmark

Run the same calls on both, compare the measured latency, and watch the method hold. Then decide on data.
