Django app for Heroku users designed to hide your * from search engine results.

Use case

You want to develop a website called using Django deployed on Heroku. You write a little bit of Django code and create a new Heroku app called artisanalraisinbeer to deploy to.

While developing, you can visit your site by going to this URL:

Eventually, you finish the first version of your website, buy the domain name, and set everything up so that you can view the site just by going to the following URL:

You can still visit, which is fine—but there's one problem: you want your main site to show up in search results, not your site.

How it works

This app goes about this two ways: robots.txt and the X-Robots-Tag. Why both? To be double-plus sure... 👀

If herokuapp seems to be in the originating host of the user request, then we do two things:

  • Put the following in robots.txt:

    User-agent: *
    Disallow: /
  • Set X-Robots-Tag in our response header to noindex, nofollow.

For search engines that respect these settings, they should start to ignore these sites in future crawls.

Quick start

  1. Add 'hide_herokuapp' to your INSTALLED_APPS setting.

  2. Add the HideHerokuappFromRobotsMiddleware middleware to your MIDDLEWARE_CLASSES like this:

  3. Include the hide_herokuapp URLs in your project's like this:

    urlpatterns = [
       url(r'^', include('hide_herokuapp.urls')),

    alternatively, you may hook up the view directly:

    from hide_herokuapp.views import herokuapp_robots_view
    urlpatterns = [
      url(r'^robots\.txt$', herokuapp_robots_view),
