There are many tools out there. Here we don't intend to provide a complete overview, those exist elsewhere. We just want to list the few that we deem particularly useful. Please do feel free to add a comment with your own favourites! Note that Open Query does not re-sell any tools. This is a conscious decision, providing you with additional assurance that we are independent in our advice and recommendations.
