About

About

MergeMe mirrors GitHub pull requests and GitLab merge requests into Slack as a single, updating notification card per PR/MR. Unlike the official GitHub or GitLab Slack apps, which post a new message for every event, MergeMe edits one message in place as status changes (opened, in review, approved, merged). Review comments appear as thread replies under that card. Supported code hosts: GitHub, GitLab, and GitLab self-hosted. One workspace can connect multiple git sources at once. Route each repo or project to its own Slack channel, map GitHub/GitLab usernames to Slack users so @mentions actually ping reviewers, and use label-based routing to send bugs, features, and docs work to different channels. Setup takes about five minutes: connect Slack, connect your git provider (OAuth, GitHub App, or webhook URL for self-hosted), then add channel mappings. MergeMe uses webhook payloads only - it does not read your private source code. Free Hobby plan: 1 channel mapping, 5 users

Audience

Web agencies, developers and QA teams that maintain websites, especially Drupal and WordPress

Audience

Software development teams, engineering managers, and DevOps organizations that use Slack for daily communication and GitHub or GitLab for code review. Especially teams frustrated by noisy official Slack integrations, teams running GitLab self-hosted, and organizations that use both GitHub and GitLab and want one notification tool.
