 ## On hosting preferences
 
 [Heroku][8] sponsors our hosting & [Fastly][9] sponsors our CDN :heart:. While heroku does have [a fastly addon][10], for billing & maintenance reasons its easier to manage one fastly account with multiple service accounts configured in it. Heroku lets us have [pipelines][11] that enables us to have different environments like staging & production. It also lets us have review apps explained in the following section. We have hosted few apps directly on GitHub pages. These are apps where only content of the app is changed by internal teams that they don't require the sophisticated setup that the other apps enjoy.
 
-## Heroku review apps
+We've deployed apps prerendered with prember on [Netlify][19].
+
+## Review apps
 
 Heroku enables us to create [review apps][12] which are same as regular apps but lets us review changes in pull requests. They're automatically created when members with write access of a repo raise a PR (also depends on whether the pipeline is configured to auto-deploy). To create a review app for a PR raised by non-members, go to the heroku pipeline and manually create the review app. Review apps get deleted after few days of inactivity on the PR. They also get deployed only on successful builds on Travis.
 
+Creation & maintenance of review apps on netlify is automated & doesn't require manual intervention.
+
 ## Heroku deployment
 
 Heroku deployment doesn't require special deploy section on `.travis.yml` configuration file since we always setup github integration via the [heroku dashboard][13]. The deployment on heroku still checks to ensure that travis builds were successful before autodeploying the changes.
