You can check out https://usertrack.net, but it's currently $99/life. I do plan to add a free version with some limited features (no heatmaps, no session recordings, no multi-domain, etc.), but the free version should be anyway better than most of the alternatives (fast interface, segments, quick user filtering, easy to install).

If you want, you can contact me on Twitter to tell me what the free version should contain for you to consider using it, or if the current price for the lifetime version is too high for you.
