I have used SEEdit for several years now, from the PPC version through the current Intel version, and it is one of the finest HTML editors available on the Mac. I will even go so far as to say that on the Windows side I've not found an integrated editor and project manager that is its equal.

For integration, ease of use, toolkits, and support, SEEdit and Sven Olsson company are unequalled. It's main competitor is BBEdit, and while similar, the seamless and simple integration of features in SEEdit beat BBEdit for functionality.

The rapidity of development, and the responsiveness of the developer to the changing environment of HTML is to be desired in all major software. That SEEdit supports HTML5 so thoroughly is highly commendable, and efficient. This is the only tool that continually supports its user base with packages that assist development. It's on the cutting edge of development.
