QA systems — vendor directory
A working operator’s view of the main quality assurance (QA) platforms used in contact centres. Neutral synopses and links to each vendor’s official site.
This is a list of options — not recommendations. We’re not paid by any vendor on this page. Inclusion isn’t endorsement, and omission isn’t criticism. QA tooling has shifted significantly with AI-powered evaluation, so the right pick depends on whether you want manual evaluations, AI-led at-scale scoring, or a mix.

How to think about choosing a QA system
The QA market splits into three rough camps:
- Self-service / mid-market QA platforms. OptiOp, Scorebuddy, MaestroQA, EvaluAgent, Klaus — built specifically for quality evaluation, with strong workflows for evaluators, calibration sessions, and coaching follow-through. The right starting point if QA is the primary problem you’re solving and you want to be up and running quickly.
- AI-led conversation intelligence. Observe.AI, Cresta, and CallMiner approach QA from the analytics side — transcribing and scoring 100% of conversations rather than a sampled few. Bigger upfront investment, very different operating model.
- QA modules inside the bigger suites. NICE Quality Management, Verint Quality Management, Calabrio Quality Management, Playvox QA — if you already run the parent platform, this is often the path of least resistance.
