Diving into the Top Prolific Alternatives

Prolific Overview

Focused on research surveys and academic studies, Prolific taps into a crowd of over 130,000 participants. They‘ve built a reputation for high-quality survey responses, reflected in a 4.3 rating on G2. However, some users complain of high prices and inconsistent output quality.

Key Stats:

  • User rating: 4.3 on G2
  • Crowd size: 130,000+ participants
  • Focus: Academic research, surveys
  • Pricing: Pay-as-you-go, no published pricing

Prolific is a good option for academic and market research surveys, but may not suit intensive data collection projects.


As one of the largest crowdsourcing marketplaces globally, Clickworker boasts over 4.5 million contributors. Their focus spans AI/ML data annotation, research surveys, content creation, and more. With custom pricing and a free trial, they offer flexibility – likely contributing to their 4.4 rating on Trustpilot.

Key Stats:

  • User rating: 4.4 on Trustpilot
  • Crowd size: 4.5 million+
  • Focus: Surveys, AI/ML data, content creation
  • Pricing: Custom, free trial available

With a massive contributor pool and expertise across use cases, Clickworker is a leading Prolific alternative for data projects.

Amazon Mechanical Turk

As an Amazon service, Mechanical Turk (MTurk) offers quick access to 500,000+ workers to complete microtasks like data labeling, content moderation, etc. Their API integration accelerates batch jobs. However, businesses have complained about data quality variation between general and "Master" workers.

Key Stats:

  • User rating: 4.1 on G2
  • Crowd size: 500,000+
  • Focus: Microtasks, data labeling, content moderation
  • Pricing: Custom, no free trial

MTurk offers fast access to workers for microtasks, but may not suit complex data projects requiring rock-solid quality.


Appen focuses on providing training data for AI models, with dataset types spanning text, image, video and more. Their crowd of 1 million+ contributors offers scale for large projects. However, limited public pricing info makes cost assessment difficult.

Key Stats:

  • User rating: 4.3 on AIMultiple
  • Crowd size: 1 million+
  • Focus: AI/ML training data
  • Pricing: Unknown

For AI training data at scale, Appen is a leading choice – albeit with opaque pricing.

So which Prolific alternative is right for you? Here are my tips:

  • For fast microtasks, leverage MTurk and their API integration
  • For market research or academic surveys, stick with Prolific or Clickworker
