Thanks for sharing myrepos, it looks pretty interesting. I also came across gitbatch, another tool for managing local git repos.
It seems that these tools are more focused on being able to manage these repos, with myrepos offering a more granular control (I wish they had a demo though, it took me some time to understand what it does).
With repocheck I am focusing more on getting a quick report of the status of local repos. So I am prioritizing on visibility of local git repos as opposed to management. As for managing the repos, I built my project with the capability of providing tsv and json output, so that users have the freedom to use it in conjunction with other tools and scripts if needed
