# Hamming alternatives

> Hamming tests voice agents before launch. What to use when the question is what production did last night, and what you cannot check before buying.

Hamming is a voice and chat agent testing platform. Its own ordering is test before launch, red-team what could go wrong, then monitor production.

It is strong at the first of those. Generated scenarios, simulated accents, background noise and interruptions, run at high concurrency.

## Two things you cannot check before you talk to them

There is no public pricing. All three tiers say contact us, and the questions page says pricing is tailored to usage rather than sold per seat.

The documentation is behind an access code. You cannot read how a feature works before you are a prospect, which also means we could not verify how its tests reach an agent, and so this page does not claim either way.

## The agreement figure

Hamming publishes 95 to 96 percent agreement with human evaluators. It is the only figure of its kind anyone in this category publishes, and it is worth taking seriously for that alone.

> **Note:** It appears on a marketing page with no dataset, no sample size and no method. A reliability number without a method cannot be checked, reproduced or compared. Ask them for the method. Ask us for ours too.

## What to look at instead, by job

|  | Leads with | Pricing | Docs |
|---|---|---|---|
| Hamming | Pre-launch testing | Contact us | Access code required |
| Coval | Simulation before release | From $100 a month, no free tier | Public |
| Confident AI | Evaluation as test cases | Free tier, then $200 a month | Public |
| Evidova | Production conversations | Talk to us | Public |

- You want simulation and you want to read the docs first. Coval publishes its documentation and its prices.
- You want evaluations in your own test suite. DeepEval is Apache 2.0 and runs locally.
- Your question is about production, not about release. That is the gap this page exists to name.

## Simulation and production answer different questions

A simulated call tells you how the agent handles a case you thought of. Production tells you which cases you did not think of. You want both, and they are not substitutes.

Evidova does only the second. We run no simulations and we do no red teaming, so if pre-launch testing is the problem you are solving, Hamming or Coval is the answer and we are not.

What we do is read every conversation that actually happened, score it against rules you approved, and publish how far those scores agree with your own reviewers, per workspace, with the method written down.

Everything above was read on each company's own site and documentation on 5 October 2026. Pricing and features move. Check the source before you make a decision on it, and tell us if we have something wrong.
