Rectangle - Single Checkout for the Web

What it does

Rectangle is the first place where you can shop at multiple retailers like Amazon, Best Buy, Newegg, Walmart, and more. No switching tabs or losing track. We add AI on top: chat to find products, get recommendations, and use our Builder Studio to spec a full PC (CPU, GPU, RAM, etc.) with a budget and purpose in mind. Pick parts from live search results, add them to your build, and checkout once. One cart, one checkout. You decide, we execute.

Ask Rectangle anything about a product. Compare across hundreds of retailers. Buy everything in one clean checkout without opening a dozen tabs.

  I spent 3 years reverse-engineering a 40 yo stock market sim from 1986▲721

  Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
