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 [Profile (Markdown)](https://openaitools.app/tool/b2proxy.md) ## Knowt Knowt is a study platform built around flashcards and AI study tools, and it markets itself as the leading free Quizlet alternative.
