# Omnia vs Hamming

> Omnia tests duplex voice inside your cluster, gates the release on it and rolls back a bad version automatically, on one platform. Hamming is a separate testing vendor that dials in from outside and keeps call data in its cloud.

## Hamming tests voice agents, and Omnia does too, inside your cluster and as part of the release.

Omnia’s voice tests run inside your cluster, against the agent’s real tools, and the same system runs the release. Hamming is a second vendor: it dials in from outside, keeps call data in its cloud, and leaves rollout to whatever runs the agent.

## When it matters: A voice release passes every test and still sounds wrong on real lines.

**On Omnia:** The release was on a small share of calls when the live metrics dropped. Promotion stopped and Omnia rolled it back. The calls that failed became scenarios in the suite for every later version. (Omnia docs: https://omnia.altairalabs.ai/tutorials/progressive-rollouts/)

**On Hamming:** Hamming can block deployments that don’t meet thresholds. It doesn’t run the agent, so rollout and rollback belong to whatever does. (source: https://hamming.ai/enterprise)

## Tests inside your boundary

Simulated callers and adversarial probes run in your cluster, against the agent and its real tools, on providers you choose. Recordings stay with you. (Omnia docs: https://promptarena.altairalabs.ai/arena/how-to/voice/setup-voice-testing/)

Hamming: Tests dial a SIP number or connect over WebRTC; data stays in the United States by default, with EU clusters offered. (source: https://hamming.ai/enterprise)

## Testing and release in one system

The suite gates the version and the rollout watches it on live traffic, in the same system that runs the agent. (Omnia docs: https://promptarena.altairalabs.ai/arena/how-to/interfaces/run-in-ci/)

Hamming: CI integration blocks deployments below threshold; it has no rollout of its own. (source: https://hamming.ai/enterprise)

## One contract

Testing, the voice runtime, policy, privacy and telemetry come from one platform that’s free while you build. *(enterprise)* (Omnia docs: https://promptarena.altairalabs.ai/arena/explanation/duplex-architecture/)

Hamming: A testing service priced on request, alongside whichever platform runs the agent. (source: https://hamming.ai/pricing)

## Questions

**Can Omnia test a voice agent running somewhere else?**

Yes. Scenarios run against any endpoint you can reach, wherever the agent is hosted.

**Is the test harness open source?**

PromptArena, which runs Omnia’s scenarios, is Apache 2.0 and installs with npm.
