Incorrect or missing information? NZB Sources

SABnzbd only accepts NZB files as download specifications1. An NZB file contains a full specification of all Usenet articles that are needed for a download. You can get these files from sites listed below.

SABnzbd does not endorse or require the use of any specific indexer.
They all work with SABnzbd perfectly fine so long as they generate NZBs, none of these sites require specific "SABnzbd integration".
Before paying for an indexer please keep in mind that there are no guarantees and that any site could disappear at any time without notice.
