## B2Proxy

B2Proxy sells access to a large residential IP network. The headline product is a dynamically rotating residential pool covering 80 million-plus IP addresses across more than 195 locations, billed by bandwidth from about $0.7 per GB. Two adjacent products serve longer-running jobs: an unlimited residential plan billed by time with no traffic or concurrency caps, and static residential IPs rented per IP per day at around $0.12, suited to accounts that need a stable, dedicated address.

The platform is built around a self-serve dashboard. After signing up you configure an endpoint, choose location and ASN targeting, and receive proxy credentials to drop into your scraper, browser automation stack or analytics scripts. Documentation, location guides and a referral program sit alongside the console, and support is offered through chat and help articles.

Positioning is squarely on data-intensive business use cases: public web scraping, search engine rank tracking, e-commerce price and review harvesting, social media management and travel fare aggregation. The vendor emphasises compliant use of publicly available data, a no-logs stance for customer activity, and connection reliability figures such as a 99.95% success rate. Buyers typically compare it on pool size, per-GB cost and stability for long-running automation rather than on consumer-facing features.

**Pricing & Plans:** Paid, usage-based. Rotating residential proxies start from about $0.7/GB with non-expiring traffic; unlimited residential plans are billed per hour; static residential proxies start from about $0.12 per IP per day. No permanent free tier is advertised.

- **80M+ rotating residential IPs:** A large, dynamically rotating pool of ethically sourced residential addresses spanning 195+ countries and regions.
- **Geo and ASN targeting:** Pin requests to specific countries, cities or autonomous system numbers so results reflect the market you are studying.
- **Unlimited residential plan:** A time-based subscription with no traffic ceiling and unrestricted concurrent connections for heavy, continuous scraping.
- **Static residential proxies:** Dedicated, long-term IPs with unlimited traffic, priced per IP per day and available in 30+ countries.
- **Self-serve dashboard and API:** Configure endpoints, manage credentials and rotate sessions programmatically, with guides and chat support on hand.

**Strengths:** Very large IP pool with broad geographic coverage; Transparent per-GB and per-IP pricing with non-expiring traffic; Both rotating and dedicated static IP options from one console; Straightforward dashboard with documented endpoint setup

**Limitations:** Self-serve orientation means less hand-holding for complex enterprise integrations; Quality and speed of individual IPs can vary by target site and region; Unlimited plan pricing is quoted dynamically rather than published up front

## 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
