We helped the best,

I got datacenter proxies for working with mail and game bots. Speed, stability, and a wide internet channel were important. As a result, I got a working solution that fits my tasks and doesn’t require constant intervention or contacting support.

One of the nicest aspects is the support. Even for complex and unusual questions, they respond quickly and to the point, without canned replies. We spent a long time trying to figure out what the issue was when our service stopped working. The Proxyshard team joined in and together we found the problem was on our end.

We needed fast residential proxies in the USA for monitoring and scraping tasks. With Proxyshard, we got a stable connection and a good pool of IPs (especially premium ones), and have been working without unpleasant surprises. We particularly appreciated the low fraud score — for our use cases, this was critical, and Proxyshard meets this requirement.

We searched for genuine ISP proxies for a long time, not just another solution that only looks like ISP. Proxyshard gave us a trial, and these were exactly the proxies we needed for our work tasks. We noticed the following advantages: stability, normal speed, and consistent uptime—the product was not thrown together in a hurry. For us, this is one of the few options that truly lived up to expectations.

Mobile proxies proved themselves very well. The selection of locations is extremely large, they are fast, stable, and without sharp drops in speed. I use them on several of my projects, especially in trading, and everything works perfectly without failures!

Excellent implementation of the site's Core and API functionality. Integration went smoothly and painlessly, and main actions are automated quickly. For a team actively working with automation, monitoring, and internal tools, Proxyshard saves a lot of time—even at the integration stage, when we needed extra features, the team helped us upgrade the software part fast. That's why I give five stars!
