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
