## Prolific

Prolific operates a marketplace where researchers and organisations post studies and verified participants complete them for payment. The pitch is quality over volume: instead of a massive but unvetted panel, Prolific verifies participants, applies attention and honesty checks, and lets requesters filter by detailed demographic, professional, and behavioural criteria. That makes it possible to target narrow, representative groups — for example coding experts, healthcare professionals, or specific national populations — which matters when a study compares groups or needs to generalise beyond a convenience sample.

In recent years Prolific has leaned heavily into AI. Its AI offering covers human preference data for fine-tuning and reinforcement learning, safety evaluation, red-teaming, and benchmarks across languages and tasks. It also publishes a leaderboard of model quality based on human evaluation, and offers developer-facing tooling such as a human-feedback API, agent workflows, and a Model Context Protocol server so AI pipelines can call for human input programmatically. Alongside this, the original academic and market-research business remains central.

Pricing is usage-based. Requesters pay for participant rewards plus a platform fee, and researchers either fund studies per response or talk to sales for larger programmes and managed services. Because rates depend on study length, targeting criteria, and volumes, published list prices are rare — the platform directs larger customers to a sales conversation.

**Pricing & Plans:** Usage-based for requesters: you pay participant rewards plus a platform fee, with custom quotes for large or managed programmes. Participants earn per completed study; joining is free.

- **Verified, targetable participant pool:** Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
- **AI data and human feedback:** Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
- **Built-in data-quality controls:** Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
- **Fast study launches:** Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
- **Participant side with guaranteed pay:** Participants get a clear per-study reward, flexible scheduling, and a minimum pay standard enforced by the platform.

**Strengths:** Strong focus on data quality with verification and attention checks; Granular targeting that supports niche and representative samples; Fast turnaround compared with traditional panel providers; Growing AI-focused tooling including a human-feedback API and MCP server

**Limitations:** Pricing is quote-based for many use cases, which makes budgeting less transparent up front; Participant availability in some narrow demographics can be limited or slower to fill; Costs add up quickly for large multi-country or longitudinal studies

## PROXY.CC

PROXY.CC sells access to a large IP pool marketed at 90M+ addresses spanning 190+ cities worldwide, with country, state and city-level targeting available.

Operationally the platform emphasises flexible configuration. Users authenticate via username and password or IP whitelisting, can create sub-users, choose proxies from many countries, fine-tune sessions by ISP and protocol, and control rotation by time or request with auto-replacement. There are no limits on concurrent sessions or invocation frequency, and documentation covers API parameter configurations plus code samples for Python, Node.js, PHP, Go, Java, C#, Shell and Ruby.

Common use cases the provider highlights include market research, brand protection, ad verification, web scraping and crawling, SEO monitoring and social media marketing, with country and city-level geo-targeting and a stated 99.5% success rate. A proxy checker and free proxy list are offered as free tools, and the site supports many interface languages plus partner and affiliate programs.

**Pricing & Plans:** PROXY.CC prices each proxy type separately: rotating residential proxies from a per-GB rate, static residential and static datacenter proxies from a per-IP-per-day rate, unlimited residential plans from a per-day rate, and long-acting ISP proxies from a per-GB rate. Current rates and plan details are listed on the site's pricing page.

**Strengths:** Very large IP pool with granular country, city and ASN targeting; Several proxy types so teams can match rotating, sticky or unlimited needs; No limits on concurrent sessions or invocation frequency; Documented API with samples in many common programming languages

**Limitations:** Proxy pricing is split across many product lines, so cost needs careful comparison; The site is a marketing-heavy service page with limited independent performance benchmarks; Effectiveness ultimately depends on your target sites' anti-bot measures
