The Netbook of Feats aims to be the best collection of feats for use with D&D or games based on its rules by way of the SRD. The NBOF is free to all and you can use its content in your games or your publications (provided you publish under the Open Gaming License).
The Netbook of Feats is a project started in 2000 with the release of the Open Gaming License by Wizards of the Coast. It was retired in 2008 with the release of 4th Edition Dungeons and Dragons as Wizards discontinued publishing its rules as open gaming content.
With the return of D&D to the world of open gaming Downy Owlbear is bringing back the NBOF for 5th edition rules.
