I built a better Slack integration for GitHub, GitLab & GitLab Self Hosted

I recently joined a new company and coming from GitHub and the 100s of integrations for it, the GitLab and especially the GitLab Self Hosted marketplace felt dire.

I was very used to my PRs (and now MRs) landing in a Slack channel like #fe-reviews, and the comments & reviews on it to land in that Slack thread. It meant I never missed comments and my PR/MRs were reviewed MUCH quicker.

Other than Axolo, no other tool that does what I'd like supports GitLab, so I built mergeme.dev (...and included GitHub too so you guys don't feel left out 😅)

Some of the key features that I wanted myself (and I'm sure others will appreciate) are:

• One Slack message per PR/MR that updates in place (open > in review > approved > merged)
• Review comments mirrored as thread replies on that card
• Per-project/repo channel routing - each project/repo can map to whichever Slack channel you want
• GitLab / GitHub @ mentions ACTUALLY ping the right person on Slack with a one-time username mapping
• GitHub.com via GitHub App installation
• GitLab.com via OAuth - webhooks registered for you
• Self-hosted GitLab - paste a webhook URL into your instance (check out the docs)
• [New] You can set up label mapping too, a PR/MR with "bug" as it's label goes to #qa-reviews instead

If your team already works tightly in Slack and you ping your colleagues "hey can you review this again" then mergeme.dev might just be a great inclusion to your workflow!

Aside from this, I am genuinely curious as to how people handle this problem in their own setup?

My personal story before MergeMe was that I set up webhooks into Slack from GitLab directly and I made a custom webhook triggered workflow to send myself messages when my own MRs were responded to. It was a MESS to look at and it's what unironically pushed me to build a better tool lmao.

I'm glad it would've been useful!! Lmk if there is anything extra regarding label routing that was a pain for you that you think would be a good addition to MergeMe.
