Prolific is a research panel built for academic and commercial studies: surveys, experiments and longer tasks, with detailed screening. 50heads is built for a different job: one short question, fifty verified people, typically about ten minutes.
| Prolific | 50heads | |
|---|---|---|
| Best for | Studies of several minutes or more | Five-second judgments |
| Price | Participant pay (a minimum hourly rate) plus a platform fee of about a third | $0.25 an answer at Tier 1, all in |
| Study design | You build or link your survey | One question with options, in our composer or via the API |
| Screening | Hundreds of prescreeners | Country, age, gender and about 120 tags, any tier |
| Verification | ID checks and quality monitoring | Phone or ID verified. The app asks Apple or Google for an integrity check, and we reject answers from devices or app builds that fail it |
| Time for 50 responses | Often under an hour | Typically about ten minutes, not guaranteed |
| Agents | API | MCP server, REST API, webhooks |

Use Prolific when
You're running a study: several questions, randomisation, experiments, detailed screening or an ethics process.
Use 50heads when
You need a quick read on one thing (which name, which image, which line) and you want it now, at a price that lets you ask again tomorrow.
Many teams use both: Prolific for the study, 50heads for the dozens of small decisions around it.
