Two Strong Platforms, Different Strengths
ilert is one of the best PagerDuty alternatives on the market, particularly for European teams. Founded in Germany, ilert offers on-call scheduling, incident management, status pages, call routing, and heartbeat monitoring -- all with EU data residency and GDPR compliance baked in from day one. If your team is based in the EU and data residency matters, ilert deserves serious consideration.
Alert24 takes a different approach. Instead of being a pure alerting and incident management platform, Alert24 bundles uptime monitoring, dependency monitoring, on-call scheduling, multi-channel alerting, and auto-updating status pages into a single tool. The pitch is simple: detect, alert, and communicate from one platform rather than stitching together separate monitoring, alerting, and status page tools.
This is an honest comparison. For some teams -- particularly EU-based teams that need data residency guarantees -- ilert is the better choice. For teams that want monitoring and incident management in a single platform, Alert24 may be the better fit. The right answer depends on where you are, what you need, and how much operational complexity you want to manage.
Pricing: Per-User vs Per-Unit
ilert uses per-user pricing:
| Plan | Per User | 5 Users | 10 Users | 25 Users |
|---|---|---|---|---|
| Free | $0 (5 users, limited) | $0 | -- | -- |
| Starter | ~$7/mo | ~$35/mo | ~$70/mo | ~$175/mo |
| Premium | ~$16/mo | ~$80/mo | ~$160/mo | ~$400/mo |
| Enterprise | ~$40+/mo | ~$200+/mo | ~$400+/mo | ~$1,000+/mo |
Alert24 uses unit-based pricing. Each unit costs $18/month and includes 15 monitoring checks, a status page, and a team member. A free tier is available with 5 monitors and 1 team member.
At first glance, ilert looks cheaper -- and for small teams, it genuinely can be. A 5-person team on ilert Starter pays around $35/month. The same team on Alert24 pays $90/month. ilert wins on raw price at that scale.
But ilert, like PagerDuty, does not include uptime monitoring. It relies on external monitoring tools to send alerts via integrations. If you add a monitoring tool to ilert's price, the comparison shifts:
| Stack | Cost (10 users, typical) |
|---|---|
| ilert Premium (10 users) | ~$160/mo |
| Monitoring tool (UptimeRobot, Pingdom, etc.) | $30-60/mo |
| Total | ~$190-220/mo |
| Alert24 (10 units) | $180/mo |
ilert does include status pages on its Premium plan, so you do not need a separate status page tool. That is a genuine advantage over PagerDuty, and it narrows the gap with Alert24. The cost difference comes down to whether you need a separate monitoring tool alongside ilert.
The caveat: ilert's Starter plan at $7/user/month is genuinely affordable for teams that already have monitoring in place. If you are not looking to consolidate tools and just need a solid, affordable alerting platform, ilert's pricing is competitive.

Where ilert Wins
EU data residency. This is ilert's strongest differentiator. ilert is headquartered in Germany and hosts data in the EU. For European companies subject to GDPR, Schrems II considerations, or internal data residency policies, ilert removes the compliance headache of sending incident data to US-hosted platforms. Alert24 does not currently offer an EU data residency guarantee. If your legal or compliance team requires EU-hosted incident data, ilert is the clear choice.
Call routing. ilert can route incoming phone calls directly to the on-call engineer. Callers dial a number, and ilert connects them to whoever is on-call based on your schedule. This is valuable for support teams, NOCs, and any organization where external stakeholders need to reach on-call staff by phone. Alert24 does not offer call routing.
Heartbeat monitoring. ilert includes heartbeat monitoring for cron jobs, batch processes, and scheduled tasks. If a heartbeat is not received within the expected interval, ilert creates an incident. Alert24 does not have heartbeat monitoring -- you would need to use a separate tool like Cronitor or Healthchecks.io for this.
Native mobile app. ilert has dedicated iOS and Android apps for managing incidents, acknowledging alerts, and viewing on-call schedules on the go. Alert24 offers a progressive web app (PWA) with push notifications plus SMS and voice calls, but there is no native app store download.
Affordable per-user pricing. At $7/user/month on the Starter plan, ilert is one of the most affordable commercial incident management platforms available. For teams that already have monitoring in place and just need reliable alerting and on-call management, ilert is hard to beat on price.
EU-based support. ilert's support team operates from European time zones and understands European compliance requirements. For EU-based teams, this means faster response times during business hours and support staff familiar with GDPR and EU regulatory context.
Where Alert24 Wins
Built-in monitoring. Alert24 includes HTTP, DNS, SSL, and TCP monitoring out of the box. When a check fails, it creates an incident and triggers escalation automatically. With ilert, you need a separate monitoring tool to detect problems before ilert can alert anyone. The monitoring is the detection layer -- without it, your alerting platform is only as good as whatever monitoring tool you plug into it.
Third-party dependency monitoring. Alert24 monitors 2,000+ third-party service status pages -- AWS, Stripe, Cloudflare, GitHub, Twilio, and more -- and alerts you when a dependency has issues. If your production incident is actually caused by an AWS outage, Alert24 tells you before your team spends 30 minutes debugging your own code. Neither ilert nor any other alerting-only platform offers this.
Auto-updating status pages. Alert24's status pages update automatically when monitoring detects an issue. Your customers know something is wrong before they flood your support inbox. ilert includes status pages on its Premium plan, but they require manual updates or API scripting during incidents. Alert24's status pages reflect monitoring data in real time without manual intervention.
Unit-based pricing for larger teams. Alert24's per-unit pricing scales differently from per-user pricing. Each unit includes a team member, 15 monitoring checks, and a status page. For larger teams (10+ people), the total cost of Alert24 -- which includes monitoring and status pages -- is often lower than ilert plus a monitoring tool. A 25-person team on Alert24 pays $450/month for everything. The same team on ilert Premium plus monitoring could pay $430-460/month.
Lower operational complexity. One dashboard instead of two or three. When a monitor goes down, Alert24 creates the incident, pages the on-call engineer, and updates the status page -- all in a single workflow. With ilert, you are coordinating between your monitoring tool and ilert, each with its own configuration, alerting rules, and failure modes.
Post-incident reviews included on all paid plans. Alert24 includes post-incident review workflows with action items, metrics, and publishable summaries on all paid plans. Both platforms support postmortem workflows, but Alert24 bundles them with monitoring and status pages for a complete incident lifecycle.
Who Should Choose ilert
- EU-based teams with data residency requirements. If your compliance team mandates EU-hosted data, ilert is the right choice. Full stop. Alert24 does not offer EU data residency today.
- Teams that need call routing. If external stakeholders (customers, partners, support staff) need to reach your on-call engineer by phone, ilert's call routing is a feature Alert24 does not have.
- Teams that already have monitoring in place. If you are happy with your current monitoring setup (Datadog, Grafana, Prometheus, etc.) and just need a reliable, affordable alerting layer, ilert at $7-16/user/month is excellent value without paying for monitoring you do not need.
- Teams that need heartbeat monitoring. If monitoring cron jobs and scheduled tasks is critical to your operations, ilert handles this natively. Alert24 does not.
- Teams that want a native mobile app. If your on-call engineers strongly prefer a native app store experience over a PWA, ilert delivers that.
Who Should Choose Alert24
- Teams that want monitoring and incident management in one tool. If you do not want to manage separate monitoring and alerting platforms, Alert24 combines both with status pages in a single subscription.
- Teams replacing a multi-tool stack. If you are currently paying for a monitoring tool plus an alerting platform plus a status page tool, Alert24 consolidates all three at a lower total cost.
- Teams that value dependency monitoring. If knowing that AWS or Stripe is down before your team starts debugging would save you real time and stress, Alert24's third-party monitoring is a differentiator.
- Larger teams watching costs. For teams of 10-50 people, Alert24's unit-based pricing (which includes monitoring and status pages) is often cheaper than ilert plus a separate monitoring tool.
- Teams that want auto-updating status pages. If you want your status page to reflect reality without manual updates during an outage, Alert24 ties status pages directly to monitoring data.
The Honest Take
ilert is a strong product. It is one of the few incident management platforms that genuinely competes with PagerDuty on features while being more affordable and offering real EU data residency. The combination of on-call scheduling, call routing, heartbeat monitoring, status pages, and a native mobile app -- all at $7-16/user/month -- is compelling.
Alert24 differentiates on bundled monitoring. Instead of being a better alerting platform, Alert24 aims to be the only platform you need for the detect-alert-communicate workflow. Built-in uptime monitoring, dependency monitoring, and auto-updating status pages mean fewer tools to manage and fewer integration points to break.
The decision often comes down to two questions:
- Do you need EU data residency? If yes, choose ilert. Alert24 does not offer this today.
- Do you want monitoring bundled with incident management? If yes, choose Alert24. ilert requires a separate monitoring tool.
If neither of those is a decisive factor, compare total cost of ownership. Add up what you pay for monitoring, alerting, and status pages today, and see which platform gives you what you need at a price that makes sense.
