Introduction

For teams choosing between Prolific.com vs MTurk, the biggest difference is the type of workforce each platform is built around. Prolific.com focuses on verified participants for high-quality online studies, while MTurk is a broader crowdsourcing marketplace for microtasks, surveys, data validation, content moderation, and machine learning work.

A few buyer-relevant facts stand out immediately. Prolific.com offers free platform access with a pay-as-you-go model and no credit card required to get started. MTurk charges a 20% fee on worker rewards and bonuses, adds another 20% fee on HITs with 10 or more assignments, and applies a 5% extra fee for the Masters Qualification. MTurk has also announced it will close to new customers effective July 30, 2026, while existing users remain supported.

If your priority is reliable human data from verified participants, Prolific.com is the more research-centered option. If your priority is outsourcing large volumes of virtual tasks to an on-demand workforce, MTurk remains oriented around classic crowdsourcing operations.
