Exrm looks good for updating an already established application. Doesn&#x27;t look like it does anything for the initial setup and configuration of a new system though.<p>For me, the ultimate test is can I copy my application to a flash drive, walk it to a new clean system, and &quot;paste&quot; it to that new system. Go really does let me do that.<p><i>&gt; But i didn&#x27;t find any mature libraries like Phoenix.</i><p>Yup. But then I tend not to need larger frameworks with my Go apps. Like you allude to, Go apps tend to be less monolithic.
