haipproxy
Distributed proxy IP pool for web crawlers using Scrapy and Redis
...It includes crawlers that discover proxy servers, validators that test proxy availability and performance, and schedulers that manage crawling and validation tasks. HAipproxy aims to maintain a high availability proxy pool with low latency so that scraping frameworks can rotate proxies efficiently and avoid blocking during large-scale data collection. Its architecture supports distributed deployment, allowing multiple crawler workers and validators to run across different machines.
