Maze vs Respondent

Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.

Entry price

What drives the bill

The metric that actually scales your invoice.

Maze has withdrawn public pricing — its pricing page is now a feature-comparison table where every paid tier resolves to a form, so the Starter figures quoted by third-party sites are not verifiable. Panel recruitment is billed separately from the platform subscription.

Session fees are $40 B2C and $80 B2B at pay-as-you-go, falling about 30% on a large annual commitment, with a further discount for unmoderated studies. You are only charged for completed sessions — no-shows and screen-outs are free. Incentives are separate and you fund them: $100-$400 per professional B2B participant is normal, on top of the session fee.

Free tier

Free plan with a limited number of studies and responses per month.

Strengths

  • Test a Figma prototype with real users before building anything.
  • Quantitative metrics make results defensible in a product review.
  • Usable free tier for evaluation and small studies.
  • Reaches professional segments that general panels simply do not contain.
  • Verification meaningfully reduces participants misrepresenting their role.
  • No subscription commitment.

Limitations

  • Unmoderated only — you cannot ask a follow-up question.
  • Prototype testing measures a happy path, not the messy reality of a live product.
  • Bring-your-own-participants works well; the built-in panel is smaller than UserTesting's.
  • Expensive per participant once incentives are included.
  • Recruitment only, no research tooling.
  • Some fraudulent participation persists despite verification.

Best for

Product and design teams validating flows early and often.
