Anuvo is a Retell AI 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 Retell is bad — it isn't. It has a clean API, a friendly no-code studio, and honest pay-as-you-go pricing. This page is the honest comparison: where Retell wins, where Anuvo wins, and how to decide in one afternoon.
Anuvo vs Retell AI, feature by feature
Columns are honest: Anuvo Cloud is our hosted edition, Anuvo Resident is our differentiator. Retell figures reflect its published pay-as-you-go pricing and documentation.
| Anuvo Cloud | Anuvo Resident | Retell AI (cloud) | |
|---|---|---|---|
| End-to-end latency | 350 ms measured | 355 ms measured | Claims sub-500 ms; third-party tests report ~800 ms |
| Deployment | Hosted, multi-region | Inside your infrastructure (appliance or k8s) | Hosted; dedicated stable server offered on Enterprise (still in Retell's cloud) |
| Audio leaves your network? | Yes — to Anuvo's runtime | Never | Yes — to Retell's runtime |
| Third-party model dependency | Hosted model API | None | Bring-your-own-LLM friendly, but models still run in Retell's cloud |
| Billing | Per-minute + setup | Annual license, no per-minute fee | Pay-as-you-go from $0.07/min (voice engine), up to ~$0.31/min depending on model |
| Concurrent calls included | Scales on demand | Determined by your hardware | 20 included on pay-as-you-go; more on Enterprise |
| Free trial | Setup call included | Pilot deployment | $10 free credits, 60 free minutes |
| Barge-in | Yes | Yes | Yes |
| Multilingual incl. Indian languages | Yes, per line | Yes, per line | Yes (varies by model) |
| Audit logging & RBAC | Yes | Yes, on your store | RBAC on Enterprise; BAA via compliance portal |
| Integration ecosystem | REST + webhooks | REST + webhooks (in-network) | Larger — no-code studio, more third-party integrations |
| Maturity & community | Newer — docs and SDKs in place | Newer — docs and SDKs in place | More mature, larger community |
| Production proof | Live in a working hospital | Live in a working hospital | Broad production base |
Latency figures for Retell are its published claims and third-party measurements — verify independently. Our numbers come with a published method you can reproduce. Retell pricing is per-minute and varies by voice engine and LLM; check their pricing page for current terms.
How to decide, in one afternoon
Choose a cloud voice platform (Retell 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 want a no-code studio and a large integration ecosystem.
- You want to bring your own LLM and pay strictly per minute with no monthly commitment.
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.

Moving from Retell 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.
