The development of technology is currently growing very rapidly, especially in the increasing use of computing technology. Along with the times, computing technology has achieved extraordinary convenience and comfort in carrying out activities, including the use of the internet. Almost all internet activities require storage space, data storage limitations are often encountered when storing data on a computer or laptop. With the existing limitations, it is necessary to store files that need to be moved to an internet database such as on a website. However, to increase the convenience and ease of accessing data on various different devices, a system that is automatically synchronized in real time is needed. Realtime is where when there is a change in data, at that time the website in the browser also changes or at least a notification appears. Thus, websocket can be applied as a solution for realtime data synchronization, websocket is designed to be implemented in web browsers and web servers. The results of the implementation and testing carried out show that real-time document storage websites can be done using the websocket method, websocket can receive more requests than websites without websocket, namely 8000 requests when websocket runs in 5 seconds of testing. The percentage of websocket success when sending data reaches 100%. The QoS measurement results obtained the average delay value of 124 KB file size of 0.2479 seconds, 505 KB file size of 0.2874 seconds and 1.32 MB file size of 0.8231 seconds. The average jitter value for a 124 KB file is 0.1108 seconds, a file size of 505 KB is 0.1252 seconds and a file size of 1.32 MB is 0.1137 seconds and from the overall data tested, packetloss is obtained at 0%.
