Pholcus is a distributed, high-concurrency web crawler framework written in pure Go. It supports standalone, server, and client modes with Web UI, GUI, and command-line interfaces, plus pluggable static (Go) and dynamic (JS/XML) crawl rules.

Use cases

  • scrape websites at high concurrency in Go
  • run a distributed crawling cluster with task distribution
  • crawl JavaScript-heavy pages with a headless Chrome downloader
  • export scraped data to MySQL, MongoDB, Kafka, CSV, or Excel
  • rotate proxy IPs and manage cookies to avoid blocking
  • resume interrupted crawl jobs from persisted state

When to choose

  • you need a full-featured Go crawler with distributed task scheduling out of the box
  • you want both static and hot-reloadable dynamic crawl rules
  • you need multiple output targets like databases, message queues, and files
  • you want built-in proxy rotation, retry, deduplication, and checkpointing

When to avoid

  • you need a lightweight single-purpose scraper rather than a full framework
  • your project is not in Go and you cannot use Go rules
  • you require a maintained ecosystem with frequent updates and large community support
  • legal restrictions in your jurisdiction prohibit web scraping for your use case
