The bottom part of the dropout appeared to be slightly bent toward the exterior.
Is my frame still rideable? There isn't any damage on the frame except this.
(And no, the tools on the picture where not used on the bike

For that to happen in the first place, your chain was likely much too loose. You should be able to bend the dropout back and reinstall your wheel without any problems.
