Compared honestly, on the questions you actually score.
Below is Zenius next to the three vendors most often on the same shortlist — QA Wolf, Rainforest QA and Testlio — compiled from their public materials in September 2026. Each is a good company; they solve different problems. If a vendor tells us a row is wrong, we correct it.

Compiled September 2026 from vendor websites and public reports: QA Wolf pricing, QA Wolf SOC 2 announcement, Rainforest QA and reported Rainforest pricing (Bug0, May 2026), Testlio pricing. "Not marketed" means we could not find the capability in the vendor's public materials — ask them directly. Trademarks belong to their owners.

Scoring guidance
Three questions that separate a tool from a function.
Most QA RFPs score coverage percentage, price per test and integrations. Those matter, but they don't tell you whether a release is safe. Add these three rows and the shortlist reorders itself.
- Who signs? Which named person is accountable for the go/no-go, and what evidence do they attach? A dashboard cannot be held accountable.
- What happens on the peak? Is the biggest revenue day rehearsed at scale weeks before, with a person on standby during it — or is that "out of scope"?
- What do we keep? If the contract ends, do the tests, pipeline and evidence stay in a format your team can run tomorrow?
