No surprise bills.

Results are only lined up side by side when both versions took exactly the same test.

No misleading before-and-after charts.

We tell you whether an improvement is real or just luck, in plain language.

Ship updates with confidence.

Open any question and replay, step by step, what your agent did and why it was marked wrong.

Fix the right thing, faster.

If something breaks on our side or yours, it’s flagged separately instead of lowering your score.

Scores you can stand behind.

If the underlying model changes partway through a test, we catch it and tell you.

No mixed-up results.

Run the tests on your real agent, with the same setup your customers use.

Results that match the real world.

Bring in logs you already collect, pick the cases that matter, and they become part of your test set.

Your tests grow with your product.

Now try it on your own agent↓

Public tests are a start. Expert ones tell buyers more.

EveryBench is free. When you want tests written by people who do the job, Eva has them ready.
