ActiveX and Java Web Start, etc all tried to do this, and all of them ended up deprecated and out of favor for native web solutions.
Java IDEs did a lot of this for many years (Eclipse, IntelliJ, NetBeans, JDeveloper, etc) and they worked reasonably well on the desktop, but had no path to offering a web hosted solution (like gitpod or codespaces)
There are not a lot of options here, compiling down a native solution to wasm and running it in the browser would work, I'm not sure if the performance would be substantially better or more consistent across all OS'es and web unfortunately.
So we are where we are :)
Not really. Electron is basically web browser.
The issue is that a cornerstone of modern development is basically "don't rewrite what already has been written", however the problem is that you always get optimization creep because of this - people just build shit on top of other shit continuously and never go back and optimize.
Qt is pretty good at this actually. I don’t have a Mac, but building the same codebase for windows, linux, and a wasm target was pretty neat the first time I did it.
1) It's normal for Kiro (and almost every AI editor) to use a lot more CPU when you first start it up, because it is indexing your codebase in the background, for faster and more accurate results when you prompt. That indexing should complete at some point
2) On initial setup of Kiro it will import and install your plugins from VS Code. If you have a large number of plugins this continues in the background, and can be quite CPU heavy as it extracts and runs the installs for each plugin. This is a one time performance hit though.
3) If your computer is truly idle, most modern CPU's get throttled back to save power. When the CPU is throttled, even a tiny amount of CPU utilization can show up as a large percentage of the CPU, but that's just because the CPU has been throttled back to a very slow clock speed.
In my setup (minimal plugins, medium sized codebase, computer set to never idle the processor clock) I rarely see Kiro helper go above .4% CPU utilization, so if you are seeing high CPU it is likely for one of the above reasons.
Is there any way to control this? I have my files.watcherExclude setting, does it respect that?
