Alert24 vs Cachet: Managed SaaS or Self-Hosted Open Source Status Pages?

Two Different Approaches to Status Pages

Cachet and Alert24 solve overlapping problems in fundamentally different ways. This comparison tries to be genuinely honest about both.

Cachet is an open-source, self-hosted status page system built in PHP. You deploy it on your own server, connect it to your infrastructure via its API, and maintain full control over the data, design, and hosting. It is free, well-architected, and has been the go-to open-source status page for years. The project has earned its reputation by doing one thing well: giving teams a clean, API-driven status page they fully own.

Alert24 is a managed SaaS platform that bundles uptime monitoring, incident management, on-call scheduling, and public status pages into a single service. You pay a monthly fee and manage none of the infrastructure.

These are different philosophies, not different quality levels. The right choice depends on what you need and how much infrastructure you want to manage.

Pricing: Free vs Managed

Cachet is free. It is open source under the BSD 3-Clause license, and there is no paid tier, no enterprise upsell, no usage-based billing. The only cost is the server you run it on and the time you spend maintaining it.

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.

You cannot compete with free and open source. If budget is the deciding factor, Cachet wins outright. The question is whether the operational cost of self-hosting and the features you need change the calculus.

Feature Comparison

Where Cachet Wins

It is free and open source. Cachet is BSD-licensed, community-maintained, and costs nothing to use. For teams that value open source and have the skills to self-host, this is not a small advantage -- it is the entire point. No vendor lock-in, no pricing changes, no dependency on a company's roadmap.

Full design customization. Cachet uses Blade templates and allows complete CSS customization. You can make your status page look exactly the way you want -- matching your brand down to every pixel. Alert24 supports custom branding and custom domains, but you are working within its layout system. If pixel-perfect status page design matters to your team, Cachet gives you far more control.

Component-level status with groups. Cachet has a thoughtful component system with grouping, ordering, and per-component status levels. You can model your infrastructure with fine-grained detail. Alert24 supports components as well, but Cachet's component model was its primary design focus and it shows.

API-first architecture. Cachet was designed API-first. Every aspect of the status page -- components, incidents, metrics, subscribers -- can be managed programmatically. If your workflow relies on updating status pages from CI/CD pipelines, monitoring scripts, or automation tools, Cachet's API is comprehensive and well-documented.

Custom metrics and graphs. Cachet supports custom metrics with built-in graphing. You can push response times, queue depths, or any numeric data to Cachet and display it on your status page. This is a genuinely useful feature that adds transparency beyond simple up/down status.

Complete data ownership. Your status page data never leaves your infrastructure. For teams with regulatory requirements, data sovereignty mandates, or a general preference for self-hosting, this is not optional -- it is a requirement. Alert24 does not offer a self-hosted deployment.

Multi-language support. Cachet has community-contributed translations for dozens of languages. If your status page serves a global audience and needs localization, Cachet has this covered out of the box.

No vendor dependency. Cachet runs on your servers. If the project's development slowed (or stopped), your status page would keep running. Your status page infrastructure is not tied to a company's financial health or pricing decisions. That independence has tangible value, especially for long-lived projects.

Where Alert24 Wins

Monitoring is built in. Cachet is a status page system. It does not monitor your services -- it displays the status you tell it about. You need a separate monitoring tool (Uptime Kuma, Prometheus, Pingdom, or something else) to detect outages, and then you need to wire that monitoring tool to Cachet's API to update the status page. Alert24 combines monitoring and status pages in one system: when a monitor detects downtime, the status page updates automatically. No integration work, no glue code, no additional tools.

Incident management beyond status updates. Cachet handles incident creation and status updates. Alert24 adds severity levels (P1 through P4), assignments, escalation policies, timelines, and structured incident workflows. If your team needs to track who is handling an incident, what has been done, and what the customer-facing impact is, Cachet does not provide that structure.

Postmortem workflows. After an incident is resolved, Alert24 provides postmortem templates with action items, incident metrics, and publishable summaries. Teams can conduct structured post-incident reviews and publish findings to the status page. Cachet does not have postmortem functionality -- you would need a separate process or tool.

On-call scheduling and escalation. Cachet has no concept of on-call. When an outage happens, someone needs to notice (via a separate monitoring tool), then manually update Cachet. Alert24 has on-call rotations, overrides, vacation coverage, and multi-tier escalation policies. If the primary on-call does not acknowledge within a configured timeout, the alert escalates. This is an entirely different category of functionality.

Slack, Teams, and Google Chat integration with actions. Alert24 integrates with Slack, Microsoft Teams, and Google Chat not just for notifications, but for interactive incident response -- team members can acknowledge and resolve incidents directly from chat. Cachet does not have native chat integrations.

Auto-updating status pages. Alert24's status pages update automatically based on monitoring data and incident state. Cachet's status page shows what you tell it to show. If you forget to update the status page during an outage (which happens more than teams like to admit), Cachet stays green while your service is down. Alert24's monitoring-driven approach means the status page reflects reality even when humans are busy fighting the fire.

Status pages that survive your outages. A self-hosted status page has an inherent problem: if your infrastructure goes down, your status page goes down with it. Alert24's status pages are hosted on independent infrastructure. When your customers need to check if you are down, the status page is still up.

Third-party dependency monitoring. Alert24 monitors 2,000+ third-party services -- AWS, Stripe, Cloudflare, GitHub, Vercel, and more. When your outage is caused by an upstream provider, Alert24 surfaces that context before your team spends time debugging your own systems. Cachet does not track third-party status.

Subscriber notifications across channels. Both tools support subscriber notifications, but Alert24 notifies via email, SMS, Slack, Teams, and webhooks. Cachet supports email notifications for subscribers. If your users want SMS alerts or Slack notifications when you post an incident, Alert24 covers more channels.

SLA tracking. Alert24 includes SLA tracking with breach alerts and compliance reports. If you need to demonstrate uptime commitments to customers or track SLA performance, this is built in. Cachet displays uptime metrics but does not have formal SLA management.

The Self-Hosting Question

The choice between Cachet and Alert24 is largely about self-hosting and scope.

Cachet is the right choice when:

• You want a status page and already have monitoring covered separately
• You have PHP hosting infrastructure (or are comfortable setting it up)
• You want full design control over your status page
• You have the skills and time to maintain the deployment -- updates, database backups, server security, SSL certificates
• Data sovereignty or regulatory requirements mandate self-hosting
• You value open source and want no vendor dependency
• Budget is a hard constraint

Alert24 is the right choice when:

• You want monitoring, incident management, on-call, and status pages in one tool
• You do not want to maintain status page infrastructure
• Your status page needs to stay online even when your infrastructure is down
• You need structured incident workflows, not just status updates
• You want postmortem workflows and SLA tracking built in
• Your team uses Slack, Teams, or Google Chat and wants to acknowledge and resolve incidents from chat
• Automatic status page updates (driven by monitoring) matter more than pixel-perfect customization

Acknowledging the Gaps

Alert24 has real limitations compared to Cachet that are worth stating plainly:

• You cannot compete with free and open source. Cachet costs nothing. Alert24 starts at $18/month. For many teams, especially those already comfortable with self-hosting, the managed service fee is hard to justify.
• Less customizable. Cachet gives you full template and CSS control. Alert24 supports custom branding and domains, but you cannot redesign the layout from scratch. If your status page design needs to match a specific brand guide precisely, Cachet is more flexible.
• No self-hosting option. If your organization requires on-premises deployment, Alert24 is not an option. Full stop.
• No custom metrics. Cachet's ability to display custom metric graphs on the status page is a feature Alert24 does not match. If you want to show response times or custom data points on your public status page, Cachet does this better.

Who Should Choose Cachet

• Teams that already have monitoring and just need a clean, customizable status page to communicate with users.
• Organizations with self-hosting mandates -- regulatory, compliance, or policy-driven requirements for on-premises tooling.
• Teams with PHP/Laravel experience that can comfortably deploy, customize, and maintain a Cachet installation.
• Projects with tight budgets where $18/month per unit is hard to justify but server time is available.
• Teams that value open source and prefer tools they can inspect, modify, and control completely.
• Anyone who needs deep design customization of their status page -- Cachet's template system is more flexible than any managed SaaS.

Cachet is a solid, well-designed open-source project. If it fits your needs and you have the infrastructure skills, it is a genuinely good choice. The open-source community that maintains it deserves respect.

Who Should Choose Alert24

• Teams that want one tool for monitoring, incidents, and status pages. If you are currently running separate tools for monitoring, on-call, and status pages (or considering Cachet plus a monitoring tool plus PagerDuty), Alert24 consolidates all of it.
• Teams without infrastructure staff to maintain a self-hosted status page. If nobody on the team wants to be responsible for keeping Cachet running, a managed service removes that burden.
• Teams that need incident management workflows. Severity levels, escalation policies, on-call rotations, postmortem workflows, and structured incident timelines go well beyond what Cachet provides.
• Customer-facing teams that need a status page that never goes down. If your status page runs on the same infrastructure as your product, both fail together. Alert24's independently hosted status pages avoid this problem.
• Teams that need postmortem workflows to conduct structured post-incident reviews, track action items, and publish findings.

Can You Use Both?

Yes. Some teams use Alert24 for monitoring, on-call, and incident management while running Cachet as their public-facing status page. Alert24's API and webhooks can push incident updates to Cachet, giving you Cachet's design flexibility with Alert24's operational workflows behind it.

This is a reasonable architecture if you care deeply about status page design but also need managed incident response.

The Bottom Line

Cachet is one of the best open-source status page systems available. It does status pages well, it gives you full control, and it costs nothing. If you need a status page and you are comfortable with self-hosting, Cachet is a strong, proven choice. We respect the open-source community that built and maintains it.

Alert24 is for teams that want the full operational workflow -- monitoring that detects problems, on-call scheduling that routes alerts to the right person, escalation policies that ensure nothing falls through the cracks, incident management that tracks response, postmortem workflows that drive improvement, and status pages that update automatically through all of it. The value is not in the status page alone (Cachet does that well for free) but in everything surrounding it.

If you need a status page, Cachet is excellent. If you need a status page that is part of a complete incident response system, that is where Alert24 earns its price.
