Page the right person with full context
Pipe alerts from monitoring, webhooks, email, or your API into Alert24. Enrichment rules add context, escalation policies decide who's next, and on-call schedules make sure a real human gets paged — on email, SMS, voice, push, or chat.
A PagerDuty alternative built into your monitoring and status pages.
From signal to the right human
Every alert follows the same path — so what reaches a pager is filtered, enriched, and routed, not just forwarded.
Signal comes in
From Alert24 monitoring, an inbound webhook, an email, or the REST API. Any tool that can fire an alert can reach Alert24.
Rules & enrichment
Notification rules filter by severity, source, and tags. Enrichment rules add context so the alert arrives ready to act on — not just a cryptic line.
Escalation policy
Time-based escalation walks through levels until someone acknowledges. Severity increases can restart the policy from the top.
The right human, right channel
On-call schedules resolve who's responsible right now. They get paged via email, SMS, voice call, push, or chat — and can ack from any of them.
Reach people where they already are
Direct paging, chat apps, the other alerting tool you haven't fully migrated off, your ticketing system, or a plain webhook — Alert24 delivers to all of them.

Escalation policies & on-call schedules
Define exactly what happens when an incident fires — and what happens if no one answers.
Multiple levels
Stack levels so an unacknowledged alert moves from the primary responder to the backup to the whole team.
Time-based escalation
Each level has its own wait window. No ack in time? Alert24 automatically pages the next level.
Restart on severity
When an incident's severity increases, the policy can restart from the top so the bigger problem gets louder.
On-call rotations
On-call schedules rotate responsibility across your team so escalation policies always page whoever is actually on call right now — not whoever was on call last week.
Acknowledge anywhere
Responders acknowledge straight from the email or SMS they receive — no login required. Acking stops the escalation before the next level gets paged.
Don't get paged twice for the same thing
Alert fatigue is its own outage. Alert24 keeps the noise down so the pages that do come through actually matter.
Deduplication
Repeated signals for the same problem fold into one incident instead of spinning up a new page every time a check fails.
Batching & digests
Group lower-priority notifications into digests so a noisy night doesn't turn into hundreds of separate buzzes.
Severity filtering
Notification rules decide what actually reaches a human. Low-severity events can stay in the timeline; critical ones page immediately.
Auto-resolution
When the underlying check recovers, Alert24 can auto-resolve the incident and stop the escalation — no manual cleanup.
Works with what you already have
You don't have to rip out your monitoring stack. Alert24 ingests alerts from the tools already watching your systems and routes them through the same rules, enrichment, and escalation as everything else.
Email-to-incident
Forward alert emails to a dedicated address to open incidents.
REST API
Create and update incidents programmatically from anywhere.
Webhook ingest
Accept webhooks from monitoring tools and turn them into incidents.
Ingest alerts from
The alert is just the beginning
Severity & status
Incidents carry severity (low to critical) and move through investigating, identified, monitoring, and resolved.
Timelines & AI RCA
Every incident keeps a full timeline, and AI root cause analysis surfaces what likely changed.
Status pages update
Connected status pages update automatically and subscribers get notified — without anyone posting manually.
Frequently asked questions
Is Alert24 a PagerDuty alternative?
Yes. Alert24 covers the core on-call workflow teams use PagerDuty for — on-call schedules, multi-level escalation policies, multi-channel paging, and acknowledgment — and bundles it with uptime monitoring and status pages in one platform. You can also integrate with PagerDuty and Opsgenie directly if you're migrating gradually or running them alongside Alert24.
How does an alert reach the right person?
Incoming signals (from monitoring, webhooks, email, or the API) pass through notification rules that filter by severity, source, and tags, then enrichment rules that add context. The matching incident triggers an escalation policy, which resolves who's on call from your on-call schedule and pages them via their configured channels — email, SMS, voice, push, or chat.
What channels can Alert24 page on?
Direct channels include email, SMS, voice calls, and push notifications. Alert24 also delivers to chat apps (Slack, Microsoft Teams, Discord, Google Chat, Telegram, Mattermost, Webex), paging and alerting tools (PagerDuty, Opsgenie, Moogsoft, BigPanda, FireHydrant), ticketing systems (Jira, Zendesk, Freshdesk, ServiceNow), and any generic webhook endpoint.
Can responders acknowledge without logging in?
Yes. Responders can acknowledge incidents directly from the email or SMS link they receive — no app or login required. Acknowledgment stops the escalation so the next level doesn't get paged unnecessarily.
How do escalation policies work?
Escalation policies have multiple levels with time-based escalation: if no one acknowledges within the configured window, the alert moves to the next level. Policies can also restart from the top when an incident's severity increases, so a problem that gets worse gets louder.
Can Alert24 ingest alerts from tools I already use?
Yes. Alert24 accepts inbound alerts via email-to-incident, the REST API, and webhooks from monitoring tools like Datadog, Grafana, Prometheus, and anything else that can POST a webhook. Incidents created this way flow through the same rules, enrichment, and escalation as everything else.
