You can use GitHub's Gists to embed your code blocks via the Oh See Gists add-on.
You can use Statamic's redirect tag plus a custom blueprint to setup dynamic HTTP redirects on your Statamic website.
Statamic includes a built-in mechanism for setting up 301 and 302 HTTP redirects.
By default, when you output content from a field into a template, Statamic will attempt to run that content through the Antlers templating language.
With Statamic v3, you can generate static sites which means you can deploy to services such as Netlify, AWS S3, Now, etc.
