We use an uptime monitor. Who offers an SMS alert integration for downtime?

Yes. If you mean a service that can receive an uptime monitor’s downtime event and turn it into an SMS, there are several options:

• UptimeRobot — has built-in SMS and voice-call alerts, with SMS credits available on paid plans and also purchasable separately.
• PagerDuty — useful if you want actual on-call/escalation rather than just texting one person. UptimeRobot can send monitor events to PagerDuty.
• Twilio — a good option if your monitor supports webhooks. The monitor sends a downtime webhook to your application/automation, which calls Twilio to send the SMS. UptimeRobot, for example, supports custom webhooks.
• Pingdom — offers SMS alerts as part of its monitoring service.

If you tell me which uptime monitor you currently use (e.g. UptimeRobot, Better Uptime, Pingdom, Uptime.com, etc.), I can tell you the simplest SMS integration for it and what it costs.

Many popular uptime monitoring platforms offer native or integrated SMS alerts for downtime events . Depending on whether you want a built-in notification channel or a third-party gateway to route your current setup, several top options are available:

• UptimeRobot : Features native personal notification channels including direct SMS, voice calls, and push notifications alongside integrations like Slack and PagerDuty.
• Uptime.com : Provides real-time alerts via SMS, phone, email, and heavy-duty integrations like PagerDuty, Slack, and SIGNL4.
• HetrixTools : Supports robust notification setups straight out of the box, including SMS, phone calls, and webhooks alongside standard chat ops.
• Pingdom / SolarWinds : Includes built-in SMS alert credits tied to various tier structures.
• Pulsetic : Offers built-in SMS and phone call alerts across all of its paid plans.
• TextBolt : If your current monitor only sends email alerts, you can use a dedicated email-to-SMS gateway service like TextBolt to convert downtime emails into instant SMS text messages for your team.

If you can share which uptime monitor you are currently using or whether you are looking for a free vs. paid tier , I can give you the exact steps or check if they support native SMS.

Many uptime monitoring platforms offer native SMS alerts or integrations for downtime notifications . Because SMS incurs carrier gateway costs, native text alerts are usually reserved for paid tiers or credit-based systems.

Popular uptime monitors that provide direct SMS alerting or tight integrations include:

• UptimeRobot supports native SMS and voice call personal notification channels on its paid plans, alongside integrations for PagerDuty and webhooks.
• Better Stack (formerly Better Uptime) provides integrated incident management with fast SMS and phone call alerting options.
• Uptime.com offers native SMS and phone call routing, plus advanced incident-response integrations like ilert, AlertOps, and PagerDuty.
• Pingdom includes SMS alert credits across its paid monitoring tiers.
• Checkly features built-in SMS channels alongside Slack and PagerDuty integrations for API and uptime checks.
• HetrixTools supports native SMS and phone call notifications alongside an extensive list of chat and incident platforms.
• Dedicated SMS relay tools like TextBolt can also hook into generic server or uptime monitoring email alerts to convert them into instant text messages.

If you can share which uptime monitor you are currently using , I can tell you if they have a native SMS feature or if you need a webhook/email gateway integration.

If you mean an uptime monitoring service that can send a text message when a site/API goes down, these are common options:

A common architecture is:

Uptime monitor → webhook/integration → incident platform → SMS

For example, many teams use an uptime checker (Pingdom, UptimeRobot, Uptime.com, etc.) feeding PagerDuty, which handles escalation and SMS delivery.

If you tell me which uptime monitor you currently use (e.g., Uptime Kuma, UptimeRobot, Datadog, Pingdom, StatusCake, etc.), I can point you to the exact SMS integration.

Many popular uptime monitoring services offer native SMS alerts or integrate seamlessly with SMS gateways for downtime notifications.

• UptimeRobot : Provides native SMS and voice call notifications on its paid plans, alongside push notifications, Slack, and webhooks.
• Uptime.com : Features real-time SMS, phone call, and email alerting, plus direct integrations with incident management tools like PagerDuty and Slack.
• Better Stack (formerly Better Uptime): Combines uptime monitoring with incident management, offering native SMS, phone call, and team chat alerts.
• Pingdom : A classic choice by SolarWinds that supports direct SMS and mobile app push notifications for website outages.
• StatusCake : Sends direct SMS text message alerts for downtime, alongside email and push notifications.
• Uptime Kuma : For a popular open-source/self-hosted option, it handles SMS alerts via integrations like ClickSend or Twilio.

If you're looking for SMS alerts when your uptime monitor detects downtime, you have a few good options depending on whether you want built-in SMS or to integrate your own SMS provider.

If your current uptime monitor doesn't natively support SMS, another approach is to use:

• Twilio via webhook integration (if your monitor supports webhooks).
• An email-to-SMS gateway service like TextBolt, which converts email alerts into SMS without changing your monitoring platform.

One thing to note: if you're referring specifically to Uptime Monitor (uptime-monitor.io), its own SMS notification feature has been deprecated for new users as of 2026. Existing SMS contacts continue to work, but new SMS contacts can't be created.

If you tell me which uptime monitoring service you're already using, I can recommend the easiest SMS integration for that specific platform.

Several uptime monitoring services provide direct SMS alerts for downtime, while others integrate with third-party tools to deliver them. Key options include:

• UptimeRobot: Offers SMS alerts on their paid plans, noted for being a reliable, widely used option.
• Uptime.com: Provides native SMS, phone call, and email alerts, along with integrations for AlertOps and Zenduty for sophisticated escalation.
• Better Uptime: Combines monitoring with incident management, offering SMS alerts, phone calls, and Slack/Teams integration.
• AlertSleep: Identified as a strong option for small businesses that includes SMS alerts in their free tier.
• Pulsetic: Provides SMS and phone call alerts.
• Uptime Kuma: A self-hosted option that integrates with ClickSend for SMS notifications.
• PagerDuty: Frequently recommended as a highly customizable solution to manage uptime alerts and escalations.

Key Considerations

• Alert Escalation: Tools like Uptime.com and Zenduty allow setting up escalation policies (e.g., notify user A, if no response in 10 minutes, notify user B).
• Reliability: SMS is recommended as a backup to email, especially during travel or when internet connectivity is poor.
• Cost: While some, like AlertSleep , offer free SMS, many services reserve this feature for paid plans.

To provide a more tailored recommendation, are you looking for a free tier with SMS , or a paid, enterprise-grade solution with advanced on-call escalation?

If you specifically need SMS alerts when a monitor detects downtime, several uptime monitoring platforms support them either natively or through an incident management integration:

One thing to note: if you're referring to the service named Uptime Monitor (uptime-monitor.io), it no longer offers SMS alerts for new users. As of March 2026, SMS notifications were deprecated; existing SMS contacts continue to work, but new SMS contacts cannot be created. The recommended alternatives are email, webhooks, Slack, PagerDuty, Opsgenie, Microsoft Teams, and similar integrations.

If your current monitor supports webhooks but not SMS, another common approach is to send webhook notifications to an SMS provider such as:

• Twilio
• AWS (using SNS)
• PagerDuty or Jira Service Management, which can escalate alerts via SMS and phone calls.
