History​

The predecessor of Reqable was HttpCanary (an Android platform application), but we overturned all the technology stacks and rewritten it with C++ and Flutter, only keeping the logo and theme color, so the two are not much related. Of course, one of Reqable's missions is to completely replace HttpCanary. It is expected that by the end of 2023, Reqable will launch a desktop + mobile multi-platform independent application.
