AlterLab vs Proxyon
Updated March 10, 2026
Overview
AlterLab is an enterprise-grade web scraping API designed specifically for LLM and RAG pipelines. It bypasses anti-bot systems and extracts data from JavaScript-heavy sites, PDFs, and dynamic content with sub-2-second response times. Unlike general scrapers that output markdown dumps, AlterLab delivers structured JSON output optimized for AI consumption with tiered pricing by page complexity.
Proxyon provides fast residential, datacenter, and IPv6 proxies purpose-built for web scraping and automation at scale. It operates on a pay-as-you-go model starting at $1.75/GB with no subscriptions required, supports HTTP and SOCKS5 protocols, and offers city-level geo-targeting across 150+ countries with unlimited concurrent connections and 99.9% uptime.
