There are many tools for this, you can easily find them after doing some research on Google, but the point is that I wouldn't recommend this activity as you would get fake links that don't have any real value, you will increase the traffic, but won't be able to monetize it in any way, so make some efforts and try do get links manually from other reliable sources on the web.
I would like to suggest you that don't go with Link Building software and buy links, you need to build your website with manually this things will promote you your website very well on internet and you have no time then you can hire a SEO person for Build backlinks this process you should to focus on that.
