PlainProxies is a proxy infrastructure brand operated by 3xK Tech GmbH, a private German company registered in Schorfheide, Brandenburg in June 2021. The service sells residential, datacenter, ISP, and IPv6 proxies to business customers for web scraping, ad verification, and data collection.

3xK Tech GmbH was entered in the German commercial register on June 7, 2021. PlainProxies launched the same year, entering a proxy market then dominated by Bright Data, Oxylabs, and Smartproxy, with demand growing from e-commerce data collection, ad verification, and SEO monitoring.
The brand built its catalog around four proxy types. Datacenter proxies offer high-speed IPs hosted in data centers. Residential proxies route traffic through real ISP-assigned addresses from consumer devices, harder for target sites to detect. ISP proxies combine datacenter hosting with residential ISP registration for stable long sessions. IPv6 proxies supply next-generation protocol addresses for modern targets.
A distinctive product decision was the unlimited residential plan: rather than metering bandwidth per gigabyte like most competitors, PlainProxies began offering flat-rate unlimited residential bandwidth, a pricing structure it describes as a market first.
The service expanded to cover 195-plus countries with city-level targeting and a claimed pool exceeding 25 million residential IPs. Infrastructure includes the company's own autonomous systems, giving it direct control over routing rather than reselling upstream capacity entirely.
Through 2024 and 2025 the company added standard proxy market features: instant or sticky sessions up to 24 hours, 50,000 concurrent threads, RESTful API integration, and 24/7 support. A September 2024 shareholder resolution updated the company's articles regarding annual accounts and profit distribution, per commercial register filings.

The proxy industry's central ethical question is how residential IPs are sourced. PlainProxies states it compensates real users for sharing their IP addresses, positioning itself as an ethical alternative to providers that have sourced IPs through adware or unconsented SDK bundling.
No independent audit or certification of that sourcing claim was identified in records reviewed for this page. Buyers evaluating proxy ethics should review the company's terms and its consent mechanisms directly.
No direct competitors found in the same category. This could be because PlainProxiesoperates in a unique market segment or we're still building our competitor database.
