It sounds like you are looking for project management tools, rather than a webpage specifically. If that's the case then look into Trello, Basecamp, or one of the other project management tolls discussed here.

If you are looking for something to integrate your project management with the actual work you do, that will be a bit more tricky but I know you can use GitHub's services in parallel to Trello or something. Maybe someone else can post something with tighter integration, but you can always simple post GitHub links in your Trello work-items.
