GitHub Slack app alternative

Official GitHub Slack app vs MergeMe

Comparing the official GitHub Slack app and MergeMe for pull request notifications. MergeMe keeps one updating card per PR in your existing channels.

What is MergeMe?

MergeMe sends GitHub pull request notifications to Slack as one updating card per PR, with threaded review comments and @mention mapping. Teams also use it for GitLab merge requests in the same workspace.

Side-by-side

Feature	Official GitHub Slack app	MergeMe
Notification model	New Slack message per event	One message per PR, edited in place
Review comments	Often separate messages	Thread replies on the PR card
@mentions	Plain text	GitHub to Slack user mapping
Per-repo channels	Limited	Channel mappings per repository
GitLab support	No	GitLab.com + self-hosted + GitHub
Setup	GitHub Slack integration	GitHub App - no manual webhooks per repo

When teams switch

Slack channels get noisy as PRs generate many separate messages
Hard to see PR status at a glance in a busy channel
Review discussion is split across threads and standalone posts
You need repo A in #frontend and repo B in #platform
You also use GitLab and want consistent PR/MR notifications

PullNotifier is well known for GitHub. MergeMe is a better fit when you also need GitLab or self-hosted GitLab, or want multi-git routing in one workspace.
