A common moment in a growing engineering team: your site goes down, someone asks "do we have a PagerDuty?" and suddenly you're pricing a $30/user/month incident management platform for a team of four who just want to know when their API stops responding.
PagerDuty is a serious piece of infrastructure. But it's also a frequent over-purchase for teams at the wrong stage. Before you commit, it's worth understanding what PagerDuty is actually designed to do — and whether that's the same problem you're trying to solve.
What PagerDuty Is
PagerDuty is an incident management platform. Its core design problem isn't "is my site up?" — it's "when an alert fires at 3am, who gets paged, and what happens next?"
Its actual features:
- On-call scheduling (rotation management, time zones, overrides)
- Escalation policies (if tier-1 doesn't acknowledge in 10 minutes, page tier-2)
- Alert deduplication and noise suppression (grouping related alerts into one incident)
- Incident timeline and postmortem tooling
- Stakeholder communication during live incidents
- AIOps features for anomaly detection and alert correlation
PagerDuty doesn't generate monitoring data. It receives it. You still need a monitoring tool — Datadog, Prometheus, Grafana, or an uptime checker — to fire the alert. PagerDuty's value is in what happens after the alert fires: routing it to the right person, at the right time, through the right channel, and tracking the incident to resolution.
For a team with complex on-call rotations, multiple escalation tiers, and dozens of services generating alerts at all hours, that's worth the price. For a 5-person team who needs to know when their web app is down, it may not be.
What Vigilmon Is
Vigilmon is a purpose-built uptime monitoring platform. It watches your HTTP endpoints, TCP ports, and SSL certificates from multiple geographic regions, and alerts you through Slack, email, or webhooks when something goes wrong.
Its defining feature is multi-region consensus: rather than a single probe declaring failure after one bad check, Vigilmon requires a quorum of regional probes to agree before firing an alert. One CDN glitch or transient DNS hiccup in a single geography won't wake your team. Only real, multi-region outages trigger the alarm.
It also includes a built-in status page your customers can subscribe to — so when something does go down, your support inbox doesn't fill up while your team is still diagnosing.
Feature Comparison
| Feature | Vigilmon | PagerDuty | |---|---|---| | HTTP/HTTPS monitoring | Yes | No (requires external monitor) | | TCP monitoring | Yes | No | | SSL certificate monitoring | Yes | No | | Multi-region consensus | Yes | No | | On-call scheduling | No | Yes | | Escalation policies | No | Yes | | Alert routing & deduplication | No | Yes | | Incident postmortem tools | No | Yes | | Status page | Yes, included | No (separate StatusPage.io) | | Slack / webhook alerts | Yes | Yes (as output) | | Self-hostable | Yes (open source) | No | | Free tier | Yes — 5 monitors, 1-min intervals | Yes — limited (1 user, 1 schedule) | | Paid pricing | ~$10–20/month | From $21–$29/user/month | | Designed for | Developer uptime monitoring | Enterprise incident management |
The Core Distinction: Detection vs. Response
This is the most important thing to get clear:
PagerDuty is not a monitoring tool. It's an incident response tool.
PagerDuty's job begins after a monitor detects a problem and fires an alert. Its value is in routing that alert correctly: which team, which tier, which channel, with what SLA for acknowledgement. If nobody is managing on-call rotations, escalation tiers, or multi-team incident coordination, PagerDuty's core value proposition doesn't apply.
Vigilmon's job is the detection step: checking whether your site is actually up, from outside your infrastructure, continuously, with enough geographic redundancy to distinguish real outages from false positives.
For many teams — especially early-stage startups, solo developers, and small agencies — the entire incident process is "get a Slack message when it goes down, fix it, and update the status page." Vigilmon covers all of that. PagerDuty is solving a problem that doesn't exist yet at that scale.
Pricing: An Honest Look
PagerDuty
PagerDuty's plans start at $21–$29/user/month on annual contracts, depending on tier:
| Plan | Price | Features | |---|---|---| | Free | $0 | 1 user, 1 on-call schedule, no escalations | | Professional | $21/user/month | Unlimited schedules, escalations, 180-day analytics | | Business | $41/user/month | AIOps, event orchestration, postmortem templates | | Enterprise | Custom | Full platform, SLAs, SAML, dedicated CSM |
For a 5-person team on the Professional plan: $105/month, paid annually. That's before you've added any monitoring data source — you still need to pay for the tool that actually checks whether your app is up.
Vigilmon
| Tier | Cost | Monitors | Check Interval | |---|---|---|---| | Free | $0 | 5 managed / unlimited self-hosted | 1 minute | | Pro | ~$10–20/month | More monitors | 30 seconds | | Self-hosted | ~$5/month VPS | Unlimited | Configurable |
For a team that wants uptime monitoring plus status page plus Slack alerts: Vigilmon's free tier costs $0/month, no credit card required.
When PagerDuty Makes Sense
PagerDuty is the right choice when your incident management complexity actually justifies it.
Choose PagerDuty if:
-
You have multiple on-call tiers. When a primary on-call engineer must be escalated to a secondary if they don't acknowledge within a set window — and that secondary escalates to management — PagerDuty's escalation policies are irreplaceable.
-
You're coordinating across teams. When a database alert needs to route to the DBA team, a frontend monitor to the web team, and a payments error to the fintech team, PagerDuty's alert routing logic earns its keep.
-
You're running complex, multi-service architecture. When dozens of alerts can fire simultaneously during a cascading failure, PagerDuty's deduplication and incident grouping prevent alert storms from overwhelming your on-call team.
-
You need audit trails and postmortems. Enterprise compliance and SRE practice often require documented incident timelines, MTTD/MTTR metrics, and structured postmortem templates. PagerDuty's tooling for this is mature.
When Vigilmon Makes Sense
Choose Vigilmon if:
-
You want to know when your site is down. That's the core need. Vigilmon answers it cleanly, from outside your infrastructure, with multi-region verification.
-
You're a small team or solo developer. The on-call scheduling complexity that PagerDuty solves doesn't exist for a 2–5 person team where everyone is effectively always on call.
-
Alert fatigue is a concern. Vigilmon's multi-region consensus means you only get paged when a real, multi-geography outage is confirmed. Single-probe false positives — a flaky probe in one region, a transient DNS failure — don't fire.
-
You want a customer-facing status page. Vigilmon includes it. PagerDuty doesn't — you'd need to pay for a separate StatusPage.io subscription (starts at $79/month on paid plans).
-
Budget matters at your stage. Vigilmon's free tier gives small teams everything they need. PagerDuty at $21/user/month is a meaningful recurring expense before you've added the monitoring tool it actually needs as an input.
Can You Use Both?
Yes — and mature teams often do. The tools solve different parts of the problem:
- Vigilmon checks whether your app is up, verifies it from multiple regions, and sends an alert to Slack or via webhook when it's down.
- PagerDuty receives that alert and routes it: who gets paged, in what sequence, with what escalation timeline.
If you're at a stage where alert routing and on-call management are real operational problems — typically teams of 10+ with dedicated SREs and complex service architectures — running Vigilmon as the detection layer and PagerDuty as the response layer is a reasonable stack.
For teams who aren't there yet, Vigilmon's built-in Slack and webhook delivery handles the routing problem without the per-seat overhead.
Conclusion
PagerDuty is an excellent platform for enterprise incident management. If you're coordinating on-call rotations across multiple teams, managing escalation tiers, and tracking MTTD metrics against SLAs, it earns every dollar.
But it's not a monitoring tool. It doesn't check whether your site is up. And for most developer teams, the problem they're actually trying to solve — "notify me reliably when my service goes down, and let my users know the status" — doesn't require enterprise incident orchestration. It requires good uptime monitoring.
Vigilmon is built for that job. It costs less, starts faster, generates less noise (thanks to multi-region consensus), and includes the status page and alerting channels that cover 90% of what small teams need. Start free, and only add incident management tooling when you have the on-call complexity to justify it.
