Proxy Rotator is a rotating proxy service built for web scraping, market research, ad verification, SEO monitoring, price intelligence, and any workflow that needs to distribute requests across many IPs. The Rotating Proxy network has been in operation since 2017. The defining feature of the network is unified access. A single plan unlocks all four proxy types (residential, datacenter, mobile, IPv6) with no separate purchases, no per-type bandwidth pools, and equal access to the full IP inventory regardless of plan tier. The network includes over 100 million total unique IPs, with 6M+ datacenter IPs, 1M+ mobile IPs across 3G, 4G, and 5G carriers, and 16M+ IPv6 addresses. Pricing is thread-based rather than bandwidth-based. You pay for concurrent threads (simultaneous open connections through the gateway) instead of GB consumed, which makes costs predictable for high-request, low-payload workloads like SERP scraping, ad verification, and price monitoring. Plans range from small starter tiers up to enterprise volume, and a 10-thread free trial is available on request. Connection options include HTTP(S) and SOCKS5 protocols, basic auth and IP whitelist authentication, and a choice between rotating IPs (fresh IP per request) or sticky IPs (same IP for up to 30 minutes). The infrastructure runs 12 strategically placed gateway points connected via 100 Gbps ports for low-latency routing between gateways and exit nodes. Common use cases include web scraping at scale, SERP and SEO data collection, e-commerce price monitoring, ad verification, brand protection, social media management, market research, and stock or travel data aggregation.

Let's hope this is going to help me solve some more Project Euler [1] problems! [1] https://projecteuler.net/. - Source: Hacker News / about 2 months ago
Https://projecteuler.net/ for "Thinker" brain food. (it still has the issue of not being a pragmatic use of time, but there are plenty interesting enough questions which it at least helps). - Source: Hacker News / 5 months ago
I have a Project Euler (https://projecteuler.net/) account. Though I do not register at all on the leader board I will sometimes work obsessively on a problem just to make one of the level icons light up for me. There is not really competition just a tiny reward. - Source: Hacker News / 7 months ago
I do hobby programing. It is sometimes to create something (supposedly) useful. Lately though it is more discovery and a little math like. I enjoy Project Euler (https://projecteuler.net/. Recently I have been playing with superpermutations (https://projecteuler.net/) and pencil and paper is useful but filling lots of paper with lots of numbers is not that fun. - Source: Hacker News / over 1 year ago
As pointed out in a sibling comment, it appears that quote only shows up if you're logged in, but assuming you have an account and are logged in, it's on the homepage (https://projecteuler.net/), second paragraph under the following heading: > I learned so much solving problem XXX, so is it okay to publish my solution elsewhere? > It appears that you have answered your own question.

It requests to proxyrotator.com a random proxy and user agent then the response would be my proxy and user agent. The initial request is get_proxy method that returns a random proxy and user agent and then the second request is scrapy.Request that will pass my proxy and user agent as meta and headers.

I'm new to scrapy and I'm still research and development to improve my code. In my project I'm using 3rd party proxy => proxyrotator.com. Whenever I run my script its very slow. Is there any configurations in my settings.py that would improve the performance of my script? Source: over 5 years ago
