Prolific vs User Interviews

From $8 per participant/hour minimum incentive, plus platform fee

From $49 per session (pay-as-you-go; $41 and $36 on annual commitments)

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.

Per-participant recruiting fee plus the incentive you choose. Specialist B2B professionals cost considerably more.

No subscription; pay per participant.

Free to manage your own participants; recruitment is pay-per-participant.
