As the author of Twitter Tools, I can confirm it is alive and well.
Twitter Tools 3.0 beta 2 was released earlier this year:

Now that Social 2.5 is out, a final release of Twitter Tools 3.0 will be available once we have some time to finish testing. You can always grab the latest version from GitHub:

Perhaps it is worth noting that Twitter Tools is released under the GPL which includes the following:
