Ask HN: What are the best growth hacking tools?

If you decide to build a house, would you start by asking, "What are the best construction tools?" Probably not.

Start by defining what it is you're trying to do. Are you trying to get more visitors to sign up for a trial? Are you trying to lower the bounce rate on your homepage? Are you trying to get more lifetime value from your existing SaaS users? ...

A list of tools won't help if you don't know (or don't specify) what you want to do.

I think this question is too vague to be answerable.

Enterprise SaaS for example is going to be entirely different than a game for iOS.

Not open source but Colibri is pretty nice. http://colibri.io.

Also check out http://iwantgrowth.net for potential websites where you can find more resources.

For startups, we have a handful of growth hacking resources here:https://globality.be/tools?tags=Growth+Hacking

I use Mixpanel. It's really powerful and has a nice free tier from which you can test things out.
