I am looking for webmaster related scripts and tools. These scripts or tools should be web based. Things like PR check / link popularity / backlink / expired domain / ect... are exactly the kind of scripts I am looking for. I would really like unique scripts. I need the rights to the scripts so please, do not offer to sell me someone elses scripts.
Please post a demo of the script(s) and the price for the script(s). I will be interested in 1 or many.
