Web Scraping with Go: Colly vs goquery vs Rod

Why Go for Web Scraping? Go offers serious advantages for web scraping: compiled binaries with zero dependencies, goroutines for massive concurrency, low memory footprint, and excellent HTTP libraries. If you are building scrapers that need to handle thousands of URLs per minute, Go is worth considering. Let's compare the three most popular Go scraping libraries. Colly: The Batteries-Included Framework Colly is the most popular Go scraping framework. It handles request queuing, rate limiting, caching, and parallelism out of the box: package main import ( "fmt" "log" "github.com/gocolly/colly/v2" ) type Product struct { Name string Price string URL string } func main () { c := colly . NewCollector ( colly . AllowedDomains ( "example.com" ), colly . Async ( true ), colly . MaxDepth ( 2 ), ) // Rate limiting c . Limit ( & colly . LimitRule { DomainGlob : "*" , Parallelism : 4 , Delay : 2 * time . Second , }) var products [] Product c . OnHTML ( ".product-card" , func ( e * colly . HTMLEle
