We are a small businesses with limited time to do this ourselves.
Can anyone recommend a good (cheap, preferably) hosted solution for simple bug tracking?
Right now we have three products that needs bugtracking.
All we need is
Besides that a small wiki/project would be nice.
Hosted FogBugz will do all of that. It's free for one or two developers, $25/developer/month for more than that.
Lighthouse may be another option. I'm not sure how it compares to FogBugz.
I like trac a bug-tracker. There are several providers, such as ProjectHut.
EDIT: One nice thing about trac is the integrated wiki. Also, the ability to integrate Subversion is a big plus too if you happen to be using SVN for your source control.
A lot of folks like to differentiate between internal development bug tracking and customer-facing issue tracking. Something like zendesk is a good example of a customer-facing issue-tracker, which would be separate from the internal bug tracking system your developers use. If you haven't already, you might want to spend a moment to determine exactly what your customer-facing needs are, since putting the customer-facing requirements in a separate issue-tracker and taking that out of the bug-tracker may significantly change which bug-tracker works best for you.
