Native Client (NaCl) was a pioneering technology from Google designed to run compiled C and C++ code in the browser at near-native speeds. While it is now deprecated, its history and technical approach provide a fascinating look at the evolution of high-performance web computing. The Rise and Fall of Native Client

While many users never heard of it, the NaCl Web Plugin became a "unsung hero" for people using (like those from Amcrest or Dahua ). If you wanted to view your high-definition camera feed directly in Google Chrome without lag, you likely had to install this plugin.
