GitNotifier vs LGTM: What are the differences?
Developers describe GitNotifier as "Get email notifications when someone stars or forks one of your GitHub repos and follows/unfollows you". We will send you notifications when someone stars or forks one of your repositories and when someone follows or unfollows you. On the other hand, LGTM is detailed as "A simple pull request approval system for GitHub". LGTM is a simple pull request approval system using GitHub protected branches and maintainers files. Pull requests are locked and cannot be merged until the minimum number of approvals are received. Project maintainers can indicate their approval by commenting on the pull request and including LGTM (looks good to me) in their approval text.
GitNotifier and LGTM can be categorized as "Tools for GitHub" tools.
GitNotifier and LGTM are both open source tools. LGTM with 936 GitHub stars and 92 forks on GitHub appears to be more popular than GitNotifier with 195 GitHub stars and 18 GitHub forks.
