Feed Me! is a cross platform, open source RSS / Atom feed reader! Right now it should work on Windows, Linux, and OSX.
Requires sqlite3 to run.
To get it on OSX via brew run
brew install sqlite3
On Ubuntu run
sudo apt-get install build-essential
and on Windows make sure the precompiled sqlite binaries are somewhere your gcc toolchain can see them. Not sure if this works with MSVC but if you can get sqlite to run on MSVC this should work as well.
You'll have to install go then run
go get github.com/Noofbiz/FeedMe
Then to run you can just do
go run main.go
or if you want a compiled binary
go build main.go -o=FeedMe
./FeedMe
