I find PubNub extremely reliable. It's been crucial for our education platform because we rely heavily on its functionality for live sync interaction, connecting teachers and students in real-time. The whole data transfer aspect works well, especially for live interactions like scribbling between teachers and students. Additionally, PubNub made it easy to get started, even if mastering all aspects required digging into the documentation. Review collected by and hosted on G2.com.

History fetching is limited. I mean, you can hardly fetch 50 messages in one round trip. If I have to get the entire history for my use case, for scribbling data, I need to make sequential calls to get the entire data. Sequential stage was not present in PubNub. The kind of features we have, like writing on the Canvas, if the sequential message doesn't come in order, then it looks odd, and the context gets lost. So we have to build a sequencing logic on top of it. Review collected by and hosted on G2.com.
