Since Titan Launcher was officially discontinued there are currently not many alternatives, at least if you want launcher with updated Minecraft, mostly because a lot of cracked servers shut down lately.
There was also ExtremeLaunher but they've stopped updating it…
I guess the question is now what's next?
Apparently there's T-Launcher that works kinda well but that's about it, it's hard to find any good alternative, maybe if you keep using old outdated launcher and hope it will still working, but keep in mind future updates could break this.
