One idea:

• one has to upload the code somewhere (say a GitHub gist, or a github repository), so that one can download using wget
• one goes to dev.lfortran.org and enters the link to the code, it downloads to your browser and runs as usual (locally)
• Then one shares a short link such as https://dev.lfortran.org/snippet/XXX where XXX is base64 encoded link to the download

That way no server is required.
