If you've managed more than a handful of pull requests across more than one Git platform, you've probably built your own little tracking system out of whatever was free and already installed. A few browser tabs. Email filters. Maybe a Slack integration that someone turned on two years ago and nobody can remember the auth for. It works, until it doesn't — until the PR that needed the please merge today
comment gets buried under twelve identical CI notifications, or until the GitLab side of your migration stays invisible for three hours because you only had the GitHub tab open.
This is a comparison of the ways developers actually track PRs today — including PR Radar, the open-source Chrome extension we built because none of the existing options did what we wanted. We'll be honest about where each one wins and where it falls short, and we'll end with the one question that decides which tool you actually need. It's the same format we used for our package manager benchmark and our transactional email API comparison — practical, developer-to-developer, and honest about the gaps.
The five options on the table
Before the comparison, here's the shortlist. We've stayed focused on tools that monitor PR status rather than tools that try to change your PR workflow (so Graphite, Aviator, and Reviewpad are out — they solve a different problem).
- Email notifications — the default for GitHub, GitLab, and Bitbucket
- GitHub's built-in notification inbox — the bell icon, the
/notificationspage - Slack integrations — GitHub for Slack, GitLab for Slack, Bitbucket's bot
- GitHub-specific extensions — Refined GitHub, Notifier for GitHub
- PR Radar — multi-platform dashboard in the browser toolbar
Option 1: Email — the default everyone ignores
Every Git host turns on email notifications by default. Every developer turns most of them off within a month.
The problem with email isn't that it's a bad channel. It's that PR events are high-frequency and low-information per message. A typical active PR generates email for:
- The initial open
- Every review comment
- Every reply in a thread
- Every push that re-triggers CI
- Every CI status change
- Merge or close
Multiply by 8–12 active PRs in a normal week and you've built a firehose. The signal-to-noise ratio collapses because every email looks roughly the same in the preview pane: a PR title, a repo name, and one line of context. You cannot tell at a glance which of your fifteen unread messages is CI failed on the PR that's blocking release
and which is approving nit on a docs typo.
Where email wins: Audit trail. If you need a durable record of what happened and when, email is it. Good for compliance, useless for real-time awareness.
Where it fails: Real-time awareness, cross-platform visibility, CI status at a glance.
Option 2: GitHub's notification inbox
GitHub's inbox (the bell icon and /notifications) is better than email for one reason: it's scoped and threaded. A single PR becomes one inbox entry that updates in place instead of twenty separate emails.
It has genuine improvements over the last couple of years — filters, custom views, Participating
vs All,
per-repo mute. If you live entirely inside GitHub, the inbox is solid.
But it has three hard ceilings.
It's GitHub-only. If your team uses GitLab for infra and GitHub for apps, the inbox solves half your problem. The other half you track… somehow.
It doesn't show CI status inline. The inbox will tell you CI ran on this PR.
It will not tell you whether it passed or failed without a click into the PR page. For a tool whose primary job is telling you what needs your attention, burying the pass/fail state behind a click is a miss.
It needs a tab open. The inbox icon lives inside github.com. If you closed the tab during a focus block, you find out about a failed deploy the next time you cmd-T your way back. Browser desktop notifications exist but are disabled by default and, even when on, only fire when a GitHub tab is already open.
Where it wins: Native, reliable, no extra auth, granular filters.
Where it fails: GitHub-only, no CI status in the list view, tab-bound.
Option 3: Slack integrations
Slack is where most engineering teams already are, so routing PR events into Slack seems obvious. And for a few specific use cases — a dedicated #deploys channel, a release-critical PR that the whole team is watching — it's the right tool.
For everyday PR tracking, Slack is a noise amplifier. A rebase-heavy afternoon on a single PR can push twenty notifications into a channel. The team stops reading them. Important signals (production deploy failed
) end up in the same channel as unimportant ones (renovate bumped a patch version
), with the same visual weight, both probably muted by Thursday.
There's also a coverage asymmetry. GitHub for Slack is mature. GitLab for Slack is functional. Bitbucket's Slack integration exists but feels like an afterthought. If you've got repos on all three, Slack gives you an uneven view of each one.
Where it wins: Team visibility on critical events, shared context during an incident.
Where it fails: Personal PR tracking, signal-to-noise, multi-platform parity.
Option 4: Refined GitHub and Notifier for GitHub
If you've looked for browser extensions for this before, you've hit two classic options.
Refined GitHub is excellent — dozens of polish-level improvements to github.com pages. But it enhances GitHub; it doesn't pull PR status out of GitHub into your toolbar. You still need to open the tab.
Notifier for GitHub does put a badge in your toolbar, but the badge counts unread notifications — not CI state, not review state. A red badge tells you there's something
and nothing else. You click through to find out what.
Both are GitHub-only, both assume GitHub is your whole world, and neither addresses the core visibility problem if your work spans platforms.
Where they win: Free, lightweight, GitHub UX polish (Refined GitHub in particular is a staple).
Where they fail: Single-platform, no CI awareness in Notifier, no toolbar summary in Refined.
Option 5: PR Radar
PR Radar is the extension we built after rotating through all four options above and still ending up with a browser window full of tabs. It's a Chrome extension (Firefox and Edge in progress), MIT-licensed, open source, and free — no paid tier, no accounts, no backend at all. Links to the store listing and repo are at the end of the post.
The short version of what it does:
- One toolbar popup with every open PR across GitHub, GitLab, and Bitbucket
- Badge on the toolbar icon with a live pass / fail / running count for CI
- Unresolved comment count per PR, pulled via GraphQL so the number is actually correct
- Deployment status inline with clickable environment URLs
- Desktop notifications and sound alerts when CI finishes (no tab required — it polls in a service worker)
- One-click merge from the dashboard, across all three platforms
- Stale PR dimming with a configurable threshold so your attention goes to the active ones
- Keyboard shortcuts —
j/kto move between PRs,oto open,/to search,?for the full list
The design goal was minimum cognitive load: glance at the toolbar, see whether anything needs you, go back to what you were doing. If the badge is green, there is nothing to do. If it's red, you know exactly where to look. The same mindset drove our list of developer CLIs that AI agents use well — a good dev tool should compress ten decisions into one glance.
Privacy-wise, PR Radar doesn't send your tokens anywhere. Your personal access tokens sit in the browser's local storage, and the extension makes API calls directly from your browser to each Git platform. There is no PR Radar backend. We don't run analytics. There's no DeployHQ account required — the extension works whether or not you're a DeployHQ customer.
Side-by-side
| Dimension | GitHub Inbox | Slack | Refined / Notifier | PR Radar | |
|---|---|---|---|---|---|
| GitHub | ✅ | ✅ | ✅ | ✅ | ✅ |
| GitLab | ✅ (via email) | ❌ | ⚠️ Uneven | ❌ | ✅ |
| Bitbucket | ✅ (via email) | ❌ | ⚠️ Uneven | ❌ | ✅ |
| CI status at a glance | ❌ | ❌ | ⚠️ In channel | ❌ | ✅ Badge + inline |
| Unresolved comment count | ❌ | ❌ | ❌ | ❌ | ✅ |
| Deploy status in PR list | ❌ | ❌ | ❌ | ❌ | ✅ |
| Works without a tab open | ✅ | ❌ | ✅ | ❌ | ✅ Service worker |
| Sound / desktop alerts | ❌ | ⚠️ If tab open | ✅ | ❌ | ✅ |
| Merge from the tool | ❌ | ❌ | ❌ | ❌ | ✅ All 3 platforms |
| Cost | Free | Free | Free tier + Slack cost | Free | Free + open source |
| Privacy | Platform stores email | Platform | Slack + platform | Platform | 100% local, no backend |
The pattern is consistent: each mainstream option handles one or two of these well and treats the rest as out of scope. For developers who only use GitHub and already live in Slack, that's fine. For anyone working across platforms, the gaps add up fast.
The deployment connection
If you're reading this on the DeployHQ blog, there's a fair chance you care specifically about the last mile: the moment between CI passed
and change is live.
That moment is where PR tracking stops being a productivity nice-to-have and starts being a deployment-quality thing.
Two concrete examples:
Catching a broken deploy before the channel sees it. When CI includes a deploy step (either an automatic deployment from Git or a preview environment triggered by PR), the failure signal travels through the same notification pipes as every other CI event. In email or Slack, a failed deploy looks like every other failed check. In PR Radar, the toolbar flips red the moment the job changes state, with the deploy URL one click away. That's a four-second feedback loop instead of a forty-minute one.
Merging without a tab full of PRs. DeployHQ's one-click rollback and zero-downtime deployments are designed to make shipping cheap. The bottleneck in that flow is usually human: somebody has to decide the PR is ready and hit merge. If that decision point lives in a popup rather than on a PR page buried in a tab group, the whole cycle tightens.
Neither of these is the reason to install a browser extension on its own. But if you already care enough about deployment velocity to be reading this, the PR tracking side of the workflow probably deserves the same attention you've given your CI/CD pipeline and your deploy automation.
Who should pick which
Here's the actual decision tree.
You only use GitHub and you're fine with the inbox. Stay with it, maybe bolt on Refined GitHub for UI polish. No extension needed.
You only use GitHub but the inbox feels lossy. Try Notifier for GitHub for the toolbar badge. If you want CI status specifically and not just unread counts, PR Radar fits even in single-platform setups.
You use GitHub + GitLab or GitHub + Bitbucket. This is the case email, the inbox, and GitHub-specific extensions all fail at. A dedicated multi-platform tool is the only real answer. PR Radar is the one we built; there isn't much direct competition in the free / privacy-first slice of that category.
You're a team lead who wants team-wide visibility into deploys. Slack is still right for that — route release-critical events into a dedicated channel. Just don't try to use the same Slack integration for personal PR tracking; it's the wrong tool for the wrong granularity.
You care about privacy or you work on client repos with sensitive PR titles. PR Radar keeps everything local — tokens in browser storage, API calls direct to platforms, no backend, no analytics. Hosted PR tools generally require you to authorize an OAuth app that sees your PR content. That's a real trade-off worth knowing about, in the same category as picking which MCP servers you grant access to your codebase or how you wire Claude Code into Git.
Try it
PR Radar is free, open source (MIT), and takes about a minute to set up.
- Install from the Chrome Web Store (Firefox and Edge builds are in progress on the GitHub releases page)
- Star the repo on GitHub if it saves you a tab — it's how we know to keep investing in it
- File an issue if a platform quirk breaks your setup; we read all of them
If you're already on DeployHQ, PR Radar closes the visibility gap between PR looks good
and change is live
without asking you to change anything about your deployment workflow. If you're not, it's still the fastest way we've found to stop tab-hopping between Git hosts.
