Quick answer: GitDailies is the best GitHub Actions notification tool for teams that want alerts based on specific conditions. For example, the Workflow failed trigger condition, scoped to the repositories that matter, can send alerts to Slack, email, or Telegram. GitHub's built-in notifications are the free starting point. Axolo, PullNotifier, and Pullflow put CI status beside the pull request. Trunk and Datadog CI Visibility explain why the pipeline is failing. They address a different need.
A commit lands on main at 09:41. A commit hits main at 09:41. Five minutes later, the deploy workflow goes red. And then, nothing happens.
At 11:20 someone rebases onto main, watches their tests fail, and spends forty minutes reading a diff that was never the problem. At 14:00 a second pull request merges on top of the broken commit. At 16:30 an engineer opens the Actions tab for an unrelated reason, sees a column of red X marks running back seven hours, and asks in the team channel whether main has been broken all day.
Six people answer within a minute. Every one of them had seen the red X. Every one of them had assumed that someone else, closer to the problem, had already noticed.
GitHub did send notifications, to be fair. The problem is that GitHub notifies everybody about everything, which ends up having much the same effect as notifying nobody.
That is the question here: a workflow failed — who tells someone who can act on it, and how fast? The goal is simply to get that one fact to the right person who can act on it before four more merges land on top of the failure. This is about CI state, not general GitHub activity. Reviews, stale pull requests, and issue traffic belong in the parent article, Top 7 GitHub Notifications Tools.
One distinction is important here. A notification tool tells you the pipeline broke. CI observability tells you why. They solve different problems, come at different price points, and the last two tools on this list fall into the second category. Here are seven tools, ranked for the first job, starting with GitDailies.
GitDailies
GitDailies treats a failed workflow as an alert with a condition attached, which is exactly why it ranks first here.
The trigger is named on the page: Workflow failed, paired with Workflow succeeded. It sits inside a documented trigger, condition, and event model, with an expression builder behind the condition. That is what makes it a rule rather than just another notification.
You are not subscribing to a repository and hoping the noise stays manageable. You define exactly what the rule should watch: specific repositories, repositories matched by topic, or repositories selected with a regular expression. If a workflow fails in any of them, the rule fires. One rule can cover forty repositories, while the other forty nobody is watching remain quiet.
Where the alert lands is just as important. Alert notifications go to any combination of email, Slack, or Telegram — the channels the team already checks, rather than a mailbox rule that nobody has opened since March. And whoever sees the alert first is probably the person who would have ended up fixing the issue anyway.
Setup is an install, not a migration. You connect a read-only GitHub App that reads the metadata. Pricing is per pull requests per month rather than seats, and every tier includes unlimited users.
- Community is free for 50 pull requests a month across 2 repositories, with 2 shared alert rules.
- Pro covers 250 pull requests and costs $49 a month. It includes unlimited private alert rules.
- Max includes 1000 pull requests and costs $299.
The limitation is worth stating: GitDailies tells you that a workflow failed, but it does not tell you why. There is no log analysis, no flaky-test detection, no build-duration trend, and no test-level history. Trunk and Datadog handle that side of the problem. What GitDailies owns is the seven hours between 09:46 and 16:30.
Honest take: The failure you need to know about is the one that affects a repository that matters. Everything else is noise you will probably learn to ignore within a fortnight. GitDailies pairs the Workflow failed trigger with a defined scope — specific repositories, repositories matched by topic, or those matched by an expression — and sends the alert to Slack, email, or Telegram without requiring a mail rule, bot token, or YAML file to maintain. Datadog can do something similar, but it comes at $8 per committer per month and requires a broader platform adoption. The outcome is essentially the same; GitDailies just gets you there with less overhead. For an engineering team working on GitHub, this is the alert worth wiring up before buying anything larger.
GitHub's own notifications
GitHub’s built-in notifications are the obvious place to start. They’re free, already there, and often all a small team needs. GitHub can email you or notify you on the web when a workflow you’re watching fails, with no extra cost and no third-party vendor needing access to your repositories. For a small repo with three engineers keeping an eye on it, that may be more than enough. Any tool comparison that says otherwise is probably trying to sell you something.
The limitation is structural, not a missing feature. GitHub notifications are per-event: you choose which events you want to be notified about, and you cannot batch them or add conditions to them. There is a filter, but there is no real condition. "Tell me when a workflow fails" and "tell me when the deploy workflow fails on main" are treated equally by GitHub, so the second arrives inside the first, alongside draft branches and flaky nightly runs. By the time a red X on main becomes just one message in a stream of two hundred, the stream has been muted — and the muting was rational.
Actions itself is free on public repositories with no minute cap, while private repositories include a monthly allowance — 2,000 minutes on Free, 3,000 on Team, and 50,000 on Enterprise Cloud — with additional usage billed per runner-minute. Notifications cost nothing extra, and never will. Start here, and move on when muting the notifications starts to feel like the sensible option.
Axolo
Axolo takes a different approach to notifications. It creates a dedicated, ephemeral Slack channel for every pull request and archives it once the pull request is merged. Review discussion, reviewer pings, and CI status all stay in that channel. So when a check fails, the alert is not another message lost in a shared firehose. It appears right alongside the discussion about the change that caused it, in front of the people already in the thread.
For a team whose review process lives in Slack, that kind of adjacency is more valuable than it sounds. Nobody has to figure out which pull request a red check belongs to, because the channel itself is the pull request. Configurable code review timeslots also batch review requests, giving teams a way to reduce interrupt fatigue.
The free tier covers up to 50 pull request channels a month, and it includes deployment and pull request check notifications. Standard costs $8.30 per seat per month while Business is $13.30, so the bill increases with headcount. Axolo supports GitLab as well as GitHub, but Slack is the only chat platform it supports. It is a good fit for teams that want CI status to appear directly in the review conversation.
PullNotifier
PullNotifier tackles the noise problem that ruins most CI notification setups: the same pull request can generate a new message every time something changes. Instead of sending a separate message for every event, it keeps one message per pull request and continuously updates it. As the status, checks, and approvals change, the same message is updated.
That is a strong reason to choose it. A run fails, someone pushes a fix, and the run passes. With a per-event notifier, that creates two messages, and the first one is now outdated but remains in everyone’s scrollback. PullNotifier keeps it to one message that quietly updates itself. Multiply that across a busy repository, and the channel becomes something people can pay attention to instead of scrolling past it.
Notifications can be routed by repository, label, author, and reviewer, and bot-authored pull requests can be filtered out entirely. It supports Microsoft Teams natively as well as Slack, which neither Axolo nor Pullflow do. The free tier covers up to 4 team members with unlimited pull request notifications and repositories; Teams is $29 a month billed annually for up to 10 members, with additional users at $3 each.
Its unit is the pull request, which makes it a good fit for teams whose CI pain is centered on pull request checks. If that is where the problem sits in your workflow, this tool addresses it directly.
Pullflow
Pullflow is the bi-directional option, and that is a genuine capability. The pull request appears in Slack and in the editor — VS Code and Cursor — where it can be read, commented on, and approved. The sync runs both ways, so Slack is not a read-only feed of activity.
For a failed check, that changes the role of the notification. With most tools, the message sends you somewhere else: open GitHub, find the run, check the log, then come back and update the team. With Pullflow, the failure appears in the same thread where the change is already being discussed, and the response — including re-approval after the issue is fixed — can happen there too. AI review agents can also join the thread alongside humans.
The free tier is unlimited for public repositories and users, while private repositories are limited to 5 private-repo users. Team costs $5 per user per month, making it the lowest disclosed per-seat price among the Slack tools here. The tool has grown beyond a simple notifier into a collaboration hub, making it a good fit for teams that want to take action on pull requests directly from chat rather than simply see notifications there.
Trunk
Trunk is where this list moves into a different category, so it is worth describing it on its own terms. It is a CI reliability platform focused on flaky-test detection and quarantine, merge queues, and code linting, all built on top of the CI you already run. It is not a CI runner, nor is it a general-purpose “the workflow went red” notifier.
Its notification model makes that clear. The events it focuses on are test cases changing status — a test became flaky, a flake was resolved, an investigation completed — plus merge queue notifications. Build errors, out-of-memory kills, bad YAML, and timeouts are outside what this notification model is designed to handle. If the requirement is "tell me in Slack whenever workflow X goes red, for any reason", Trunk is not the right tool. Its merge queue Slack notifications are also limited to paid tiers.
What Trunk does instead is more useful than notifications. Auto-quarantine can remove a known flaky test from the merge path without a code change. Its AI failure fingerprinting can spot the same flaky test failing across different branches and show you how many pull requests it has affected. Every other tool here can only tell you that something broke. Trunk stops it from blocking you again.
The free tier is quite useful: up to 5 repository committers and up to 5 million test spans a month, with public repositories always free. Trunk does not publish a price for its Team tier — the documentation confirms only a per-seat monthly model, limited to 50 active committers. It ingests JUnit XML, so you can get a single view of flaky tests across GitHub Actions, CircleCI, Jenkins, Buildkite, and GitLab. Buy it for flaky tests, not for alerts.
Datadog CI Visibility
Datadog CI Visibility sits at the top end of this list, and it earns that position for one capability the others do not match: correlation. A failed GitHub Actions job is a trace, and from that trace you pivot straight into the APM traces, infrastructure metrics, and logs for the service being deployed. That makes questions like "Did the deploy fail because the code is wrong, or because the staging database was saturated" answerable in one product and, in some cases, with a single click. No standalone alerting tool comes close to that level of context. It also handles alerts properly, because CI signals flow through standard Datadog monitors and inherit the whole routing and escalation stack.
Pricing is what pushes it down to seventh place rather than second. Datadog charges per active git committer per month, and there is no free tier. CI Pipeline Visibility starts at $8 per committer per month and Test Optimization at $20 per committer per month, both billed annually, both US pricing. A committer is billed (considered active) if they commit at least three times in a month, and you are billed on the peak number of active committers rather than the average. One hundred active committers is $800 a month for pipeline visibility alone.
For an organization already paying for Datadog, running multiple CI systems, and needing to correlate a failed deploy to the service behind it, the cost can make sense. But if the actual requirement is simply “tell me when main goes red,” Datadog is far more platform than you need. You are taking on a full platform when a simple install would have solved the problem.
FAQs
As a developer, how do I stop getting emailed about every workflow run on every branch?
Stop subscribing to everything and start using conditions. GitHub’s notification settings let you choose which event types you receive by email, but they do not let you decide when those events should trigger a notification. So “workflow failed” can still show up from every repository you watch, including the archived ones nobody has touched in a year. A better approach is to use a tool that checks a rule before sending the alert. GitDailies pairs the Workflow failed trigger with a scope, so the alert only fires for the repositories you specify — by name, topic, or regular expression — and can be sent to Slack, email, or Telegram. Once that is working, turn off the GitHub emails. A quiet channel you trust is far more useful than a noisy one you eventually mute.
As a tech lead, should a failed pipeline page someone?
Almost never. A page is for when production is on fire, and a red build usually isn’t that. It’s a change that hasn’t shipped yet, which means there’s still time to fix it before users are affected. Page on a failed production deploy, or on the incident that follows one. For everything else, an alert in the channel the team already watches is the right level of urgency. It also keeps the pager meaningful. There’s one exception worth calling out: a failure on the default branch can block everyone else’s merges, so it deserves a loud, targeted, and hard-to-miss alert. But loud doesn’t have to mean a phone call at 3:00 a.m.
As an EM, is a notification tool enough, or do we need CI observability?
They answer different questions, and the distinction is pretty straightforward. A notification tool tells you that the pipeline broke, who needs to know, where it happened, and how quickly. CI observability tells you why it broke and whether the same problem keeps coming back — flaky tests, build-duration trends, and test-level history. Most teams need the first and believe they need the second. Start by fixing the seven hours nobody noticed, because that is a notification problem. Then consider Trunk or Datadog when you can point to a flaky test that is costing the team real time. The two are complementary; they are rarely urgent at the same moment.
Which tool should you pick?
If the failure you keep missing is a workflow going red in a repository that matters, buy the alert, not the platform. GitDailies can trigger an alert on a failed workflow with a condition attached, and send this alert to Slack, email, or Telegram. It puts the failure in front of the people who need to act on it, on the day it happened.
GitHub's own notifications are free and adequate for one small repository. Axolo, PullNotifier, and Pullflow put CI status next to the pull request. Trunk stops the flaky test from blocking the merge and Datadog correlates the failed job to the service it was deploying. Both are useful, but they solve a different problem.
The seven hours between a red X and a human noticing it is not an observability problem. It is a routing problem, and installing GitDailies on your repositories closes it in an afternoon.
