Originally a Covid project. Now a discount search engine.
Using a few different methods. Pulling the sites I'm using Puppeteer and Katana (https://github.com/projectdiscovery/katana). To process and extract the information is tricky, most websites selling things put time into their metadata; this does make it easier. Additionally, a lot of the larger stores have common patterns between them. Failing all of this, I trained a Tensor flow model to understand how to read product pages. However, it's far from perfect and a journey of continual improvement.

Show HN: Flyscrape – A standalone and scriptable web scraper in Go
Interesting. Can you compare it to colly? [0]
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?)
