![]() There are several mature OSS projects that add additional functionality, as well. NOTE: If you are using Windows or Linux, Nord provides a native command-line interface that you should use instead of this guide. (From experience: commercial proxy providers can be substantially more expensive and frustrating, particularly on small projects) This post makes no effort to break apart the large DevOps undertakings of large-scale scraping instead, we'll cover how to delay that large undertaking by using the cheap consumer VPN Nord as an automated proxy rotation service. The energizing greenfield work and short MVP times are fun - until suddenly the architecture needs to scale. Small scale scraping is the bread and butter of growth-minded engineers. You could use the OpenVPN/Tunnelblick parts of this with other VPN providers, but the code and setup will not transfer 1:1. This post and my work are not sponsored by Nord.
