Passmarked is THE tool I've been looking for to check the quality of websites (mine & clients'). The open source list of tests makes it incredibly useful and flexible for integrating into the development workflow. It's only just been launched but there's already a tremendous amount of coverage that will only get better as more people contribute.
The tool I wish I'd built!
Pros:Not upselling me a "quick fix" (like most "grade my site" tools)
open source = transparency
community driven weighting & docs
free
Cons:Not found any so far (only a day in!) :-)
The fact that everything is in one place and that some of it is community driven has been amazing for actually learning beyond quick fixes.
Pros:1 month in and this is the best website optimization tool I have ever used
Cons:None when compared to any other tool in the category.
PH should pay Passmarked for all the new aquisitions.
Pros:Great overall product
Cons:Needs further community participation, but great start.
