# MergeMe

> MergeMe mirrors GitHub and GitLab pull/merge requests into Slack as a single, live-updating card per PR/MR, with per-repo channel routing and @mention resolution.

MergeMe is a Slack integration built for engineering teams that want pull request and merge request activity surfaced directly in their Slack channels — without notification spam or tab juggling. Made by Moorlint Corporation and built in London, it connects GitHub.com, GitLab.com, and self-hosted GitLab to a Slack workspace, posting one updating card per PR/MR that evolves in place across the full lifecycle.

## What It Is

MergeMe sits between your code host and Slack, listening for webhook events and translating them into a single, editable Slack message per PR/MR. Instead of a flood of separate notifications for each status change, one card tracks the PR from draft through open, approved, and merged — updating in place. Review comments land as thread replies under that card rather than polluting the channel. The tool is webhook-driven and, according to the product page, requires no code-host API token because everything it needs comes from the webhook payload itself.

## How the Routing Works

Setup follows a five-step model: connect a code host, connect a Slack workspace, map repositories or projects to channels, link GitHub/GitLab usernames to Slack profiles, and configure notification preferences. Key routing capabilities include:

- **Per-repo channel routing** — each repository or GitLab project maps to a specific Slack channel (e.g., frontend repo → #eng-frontend)
- **Label routing** — open PRs/MRs can be routed to different channels based on labels, with the top matching rule winning
- **User mappings** — GitHub/GitLab usernames are linked to Slack profiles once, so every @mention in a PR comment becomes a real Slack ping
- **Post trigger control** — teams can gate when the first card goes out, exclude bot accounts, and toggle CI status display on cards

## Reminders Feature

A newer addition (marked "New" on the product page) lets teams schedule Slack digests of open PRs/MRs that have been sitting too long. Reminders are configurable per repo/project with staleness thresholds, digest schedules (e.g., weekdays at 09:15 Europe/London), and an option to ignore very old PRs. This targets the PR pickup-time problem — the product page cites LinearB engineering benchmarks noting that average PR pickup time on teams not actively tracking it can run 3–14 hours.

## Supported Integrations and Setup Paths

MergeMe supports three code host connection methods:
- **GitHub.com** — via a GitHub App install on an org; no per-repo webhook setup needed
- **GitLab.com** — via OAuth with automatic webhook registration
- **GitLab Self-Hosted** — via manual webhooks or a GitLab Application with OAuth, project pickers, and automatic webhooks

A self-hosted deployment option is also available for teams with data residency or SSO requirements, available by contacting the team directly.

## Deployment Model and Privacy Stance

The cloud-hosted version processes webhooks without storing private code content — the product page states MergeMe reads only what arrives in the webhook payload and holds no code-host API token. The privacy policy and terms of service are documented at mergeme.dev/docs. A self-hosted path exists for teams that need to run MergeMe on their own infrastructure.

## Current Status

MergeMe is actively shipping. The homepage references a public roadmap and changelog at roadmap.mergeme.dev, and the Reminders feature is labeled "New," indicating recent product movement. The product page reports processing over 30,000 webhooks and posting over 1,000 PR/MR cards in Slack, with over 2,600 live card updates and 1,200 threaded comments — figures presented by the vendor on the homepage.
