Prolific vs Useberry

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

From €83 per month (billed yearly)

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.

Only annual prices are published. Growth is €83 a month for 300 responses, one seat and five interviews; Business is €659 for 2,000 responses, five seats and fifty interviews; Enterprise is quoted, from 48,000 responses a year and ten seats. Responses, seats, interviews and transcription hours can be topped up within a plan.

No subscription; pay per participant.

• Notably better data quality than generic survey panels.
• Fine-grained prescreening across hundreds of demographic attributes.
• No subscription — pay only for what you run.

• Unmoderated tests and moderated interviews in one tool, so interview work needs no second subscription.
• Card sorting, tree testing and the rest of the method set are included rather than priced as add-ons.
• Recruit from your own users, Useberry's integrated pool, or through Prolific and Respondent.

• Recruitment only; you supply the study and the tooling.
• Skewed towards students and younger, online-native participants.
• Not suited to recruiting senior enterprise decision-makers.

• Interviews are metered — five a month on Growth, fifty on Business.
• The step from Growth to the next tier is steep: €83 a month to €659.
• Integrations cover design, recruitment, calendar and meeting tools; there is no issue-tracker or chat handoff.

Survey-based and quantitative studies where data quality matters and budget is limited.
