Codiad is a web-based IDE framework with a small footprint and minimal requirements and many plug-ins.
Con Full of small bugs
There are plenty of various issues and bug that may either be due to your setup and the UI will not report them, or due to bugs in the code; I'm including common plugins here as well (just naming a few: search files and in files may report nothing if it had an error, commands stderr not printed, marketplace not showing items, search in market place showing no results, Git escaping
\( in the commit message for no good reason...). Those are generally small but together it makes the product feel flawed.
