Why SaaS teams choose Sentinel

Every minute of downtime costs trust

For a SaaS product, an outage isn't an inconvenience. It's churn, SLA penalties and a flooded support queue. Sentinel verifies availability across regions, pages your team fast, and gives customers a status page so a bad hour doesn't become a lost account.

Everything you need to defend your uptime

SLA compliance reports

Measure real uptime against your 99.9%, 99.95% or 99.99% commitments and export the historical data customers and account managers ask for.

Public status page

Give users a branded status page to check during incidents. Fewer "is it down?" tickets, more trust, and a calmer support inbox.

On-call alerting

Route incidents to email, SMS, Slack, Discord and webhooks so the right engineer is paged the moment uptime slips, wherever your team works.

API & health-check checks

Watch your app, API and health endpoints, and assert on the JSON body, so an endpoint that returns 200 while reporting a degraded state still alerts.

Multi-region consensus

Every check runs from four regions and an outage is confirmed by agreement before you're paged, cutting false alarms from a single regional blip.

Incident timelines

Every outage gets an automatic detect-acknowledge-resolve timeline with root-cause detail, so postmortems write themselves and repeats get rarer.

FAQ

SaaS uptime monitoring questions, answered

What is uptime monitoring for a SaaS product?

Uptime monitoring continuously verifies that your SaaS application and its critical endpoints are reachable and responding correctly, and alerts your team the moment they aren't. It's how you protect the availability your customers, and your SLAs, depend on.

Can I track uptime against my SLA?

Yes. Sentinel measures real uptime against targets like 99.9%, 99.95% or 99.99% and produces historical reports you can use to verify SLA compliance and share with customers or stakeholders.

Can Sentinel monitor my API and health-check endpoints?

Yes. It can monitor application and API endpoints, including health-check URLs, with checks as often as every 30 seconds. JSON response assertions let it inspect the response body, so an endpoint returning 200 while reporting a degraded state still raises an alert.

How does a status page help reduce churn?

A branded public status page lets customers confirm an incident themselves and see that you're on it, which builds trust and cuts the support load during an outage. Transparency during downtime is one of the cheapest ways to retain users.

How is my on-call team alerted?

Alerts can be delivered via email, SMS, Slack, Discord and webhooks, so incidents reach whatever on-call tooling and channels your engineering team already uses.

Yes. There's a free plan to get started, and paid plans include a 14-day free trial. You can cancel anytime.
