Prolific 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
From $8 per participant/hour minimum incentive, plus platform fee
PaidFrom $40 per B2C session at pay-as-you-go, plus the incentive you set
PaidWhat drives the bill
The metric that actually scales your invoice.
You set the incentive subject to a fair-pay floor of $8/hour ($12 recommended), then Prolific adds a platform fee — around 42.8% for commercial customers, 33.3% for academic and non-profit. Budget the fee: it is a large fraction, not a rounding error. Still far cheaper than moderated-research platforms.
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.
