CI failure notifications in Slack, without the muted channel
GitLoom is a Slack-first pull request notification tool that watches your GitHub repos and, instead of pinging the channel on every failed build, sends one quiet daily digest of what is actually stuck: PRs waiting on review, blocked by conflicts, or sitting on a red check that nobody picked up.
Your CI already tells the author their build failed. What your team is missing is the follow-up: the failure that got scrolled past and is still red three days later.
Good morning. 4 pull requests need a nudge across 3 repos:
Checks failing: api#531 Upgrade Postgres client to v16 (Priya)
CI has been red on this branch since Tuesday. Nobody has picked it up.
Waiting on first review: infra#274 Add retry logic to the deploy webhook (Marcus)
Checks are green, but it has waited three days for a first review.
Approved, not merged: api#526 Fix flaky auth integration test (Sara)
Approved yesterday and never merged. This one unblocks two other PRs.
Small PR, forgotten: web#512 Bump Node base image in Dockerfile (Tom)
Eight lines, open for five days. A two-minute review.
Everything else is green and moving. Nothing else needs you today.
One quiet digest, not forty build alerts.
Everyone gets the alert. Nobody reads it.
Most teams wire CI failures into Slack the obvious way: a webhook or the official GitHub Slack app posting into a #ci or #builds channel. Every push, every check run, every red X. It works perfectly, for about two weeks.
Then the channel crosses the readability threshold. Failures from feature branches drown out failures on main. The retried build posts twice. Someone mutes the channel to get work done, then everyone does. Now you have real-time CI notifications that no human receives.
The failure mode is quiet and expensive: a PR fails checks on Friday afternoon, the author moves on, and the branch sits red until someone trips over it in standup the following week. The alert fired. It just fired into a channel that stopped being read months ago.
The muted #ci channel
Per-build alerts optimize for completeness, not attention. Once the channel is muted, your alerting system exists only on paper.
Red main that nobody owns
When every failure looks the same, the one that matters (main is broken, deploys are blocked) gets the same glance as a flaky test on a draft PR.
The PR that failed on Friday
The author saw the red check, meant to fix it Monday, and forgot. Nothing in the channel will ever surface it again.
Alert fatigue is the real bug
The problem was never a missing notification. It is that forty notifications a day trained your team to ignore all of them.
Surface what stayed broken, not what broke
GitLoom does not spam your channel per build. The morning digest lists the pull requests that stopped moving, and failing CI is one of the things it checks for directly. For live status, Live PR Cards keep one message per PR updated in place as checks run, so the channel shows current state without a new post per event.
Failing CI is a first-class category
The morning alert checks for PRs sitting on red checks directly, and lists them alongside ones waiting on review, approved but unmerged, or hit by merge conflicts, with why and who can unblock them.
Quiet by default
If nothing is stuck, GitLoom says nothing. No green-build confirmations, no per-push chatter, and flapping CI never reposts (human events always surface). Silence means everything is fine, so the channel stays unmuted.
Plain English, not payloads
No JSON-shaped webhook dumps. Each line says what the PR is, who opened it, how long it has been stuck, and what would unblock it. Readable in the time it takes to sip coffee.
Broken things resurface until fixed
A one-shot alert fires once and is gone. GitLoom keeps a stuck PR in the digest until it moves, with repeat reminders batched every few days so the follow-up never turns into spam.
From muted channel to quiet digest in two minutes
No YAML, no workflow files, no webhook URLs to paste into your CI config. GitLoom reads pull request state from GitHub, so it works with whatever CI you already run.
Install the GitHub App
Grant GitLoom the repos you want watched. Repos you select during install are tracked automatically; your code never leaves GitHub.
Connect Slack
Add GitLoom to your workspace with one click. It only posts its own reports; it never reads your channel history.
Pick a channel
Point the digest at the channel your team already reads every morning. From then on, stuck PRs surface on weekday mornings, and quiet days stay quiet.
CI notifications, answered
How GitLoom relates to build alerts, the official GitHub Slack app, and the CI setup you already have.
Your GitHub channel can stay muted.
Or tomorrow at 9:00 AM, the PR that has been red since Tuesday shows up in a channel your team actually reads.
