Website monitoring made simple

Know when your site goes down—before your customers tell you

Uptime Sentinel checks the URLs your sales and marketing teams depend on: campaign pages, booking tools, partner hubs, and internal apps. You get clear alerts and a timeline of what happened, without living in a server terminal.

  • Real-time checks and incident history
  • Email and SMS when something breaks

Built for teams who own the customer journey—not just the codebase. Monitor public sites, campaign landing pages, and the web apps your reps rely on every day.

Everything you need to stay ahead of outages

The same capabilities your engineering team expects—presented in a way GTM leaders can act on fast.

  • HTTP monitoring

    Watch critical URLs on a schedule you control. Spot slow responses and hard failures before they snowball into lost leads.

  • Browser-style checks

    Optional Puppeteer checks when the rendered page matters—forms, scripts, third-party tags, and more.

  • Screenshots on failure

    See what the monitor saw when a check failed, so you can brief stakeholders with evidence, not guesswork.

  • Multi-channel alerts

    Route downtime notifications through email and SMS so the right people wake up when revenue-impacting sites stall.

  • Incidents with context

    Track open issues, severities, and resolutions in one place instead of scattered threads.

  • Analytics that explain uptime

    Trend historical checks and aggregates so you can report reliability to leadership with numbers, not vibes.

Three steps to calmer launches

Most teams are running their first monitor in minutes—not days.

  1. 1

    Add what matters

    Drop in the production URLs, staging links, or partner pages you need confidence in.

  2. 2

    Tune notifications

    Decide who gets pinged and through which channels when response times slip or pages fail.

  3. 3

    Respond with clarity

    Review incidents, screenshots, and timelines so your team fixes issues with shared context.

Questions we hear a lot

Do I need engineering help to set this up?

No. You add the URLs you care about, pick how you want to be notified, and you are done. Technical teammates can go deeper later if you want custom checks or API automation.

What gets monitored?

HTTP and HTTPS endpoints, with optional browser-based checks when you need to validate what visitors actually see. You can track marketing sites, booking flows, partner portals, and internal tools the team relies on.

How will I know when something breaks?

You choose alert channels such as email and SMS. When checks fail, incidents are opened so your team has a clear timeline instead of guessing what happened.

Is this only for developers?

It is built for anyone responsible for customer-facing web experiences. Sales and marketing teams use it to catch downtime during launches and campaigns, while engineering can still use dashboards, APIs, and audit logs when they need them.
