Colly is a great scraping library if you are a Go developer.
Flyscrape on the other hand is a ready-made CLI tool that aims to be easy to use even for someone who is a little familiar with JavaScript. It just happens to be written in Go, but that should not matter to the end user.
It does not have full feature parity with Colly but most use cases should be covered.
Last time I looked it was the most popular choice for scraping in Go and I have some projects using it.
Is it similar? Does it have more/less features or is it more suited for a different use case? (Which one?)
