- alexellisuk 10y agoabout http://stockalert.alexellis.io/ http://stockalert.alexellis.io/ – it’s fully open source – is careful and polite when scraping – it won’t scrape an endpoint more than once per minute – pulls stock levels, too – easily extensible to send emails etc – takes < 1 second to update stock not 3-8 seconds like whereismypizero.com If you want to try it – it just needs two commands – git pull and docker-compose up. Or check out the technical deep dive for all the details on how it works in the link above.
