Feedbin is a simple, fast and nice looking RSS reader.
Feedbin is a web based RSS reader. It provides a user interface for reading and managing feeds as well as a REST-like API for clients to connect to.
The main Feedbin project is a Rails 4.0 application. In addition to the main project there are several other services that provide additional functionality. None of these services are required to get Feedbin running locally, but they all provide important functionality that you would want for a production install.
- refresher: Refresher is the service that does feed refreshing. Feed refreshes are scheduled as background jobs using Sidekiq. Refresher is kept separate so it can be scaled independently. It's also a benefit to not have to load all of Rails for this service.
- polyptych: Polyptych is an API for fetching favicons. Favicons are compiled into a singe CSS file as base64 encoded background images. Polyptych is another Rails App.
- camo: Camo is an https image proxy. In production Feedbin is SSL only. One issue with SSL is all assets must be served over SSL as well or the browser will show insecure content warnings. Camo proxies all image requests through an SSL enabled host to prevent this.
- Mac OS X or Linux
- Ruby 2.0
- Postgres 9.2.4
- Redis 2.6.13
Ultimately you need a Ruby environment and a Rack compatible application server. For development Pow is recommended.
Feedbin uses environment variables for configuration. Feedbin will run without any of these, but various features and functionality will be turned off.

These variables need to be available in the environment of the user running the app.
Locally I use dotenv combined with pow. Pow's .powenv file is set up to read dotenv's .env file like:
export $(cat .env)This is necessary so the environment variables can be read by both Pow and Unicorn.
In production environment variables are set in the app users ~/.bash_profile like:
export AWS_ACCESS_KEY_ID=aoisjf3j23oij23f
