They are advertrising use of Web technologies as something good, but it's the opposite. That Python web server will be a bottleneck because it's throughtput cannot even be compared to that of a hardware chip. It doesn't make sense to rent a "cloud" FPGA because it is ineffective. You get a vendor-locked solution with poor performance written in slow Python and Javascript. The code is on Github which means it will be buggy and always in "under construction" state (try using desktop Linux to understand what it means). As the chip is in the cloud, cloud operator can see and steal your secrets. The latency to send data to the cloud is very high. You cannot debug the chip and cannot connect a logic analyzer to it. You cannot make a hardware product with "cloud" chip. You cannot connect sensors to it. This is only usable as a toy to play with FPGA from browser. You cannot use it to control a CNC machine or video surveillance system, for example. You cannot make a guitar pedal (that someone have mentioned in comments below) with this. What developers need is cheap powerful FPGAs that they can buy and connect directly into an USB port, not a toy in the cloud.
