Uptime monitoring that just works

Know when your app goes down

Your SaaS is your business. When it goes down, you need to know immediately, not when a customer tweets about it. We check every minute from multiple locations and alert you the moment something breaks.

No agents to install, no complex setup. Add your URL and you're done.

Background job monitoring

Know when your cron jobs stop running

SaaS apps run on background jobs. Email queues, subscription billing, data syncs, report generation. When these stop running, problems compound fast.

We monitor your scheduled tasks and alert you when they fail or take too long. No more "why didn't that email go out?" debugging sessions.

Status pages build trust

Show customers you're on top of it

A status page says "we take reliability seriously." When issues happen, it gives customers a place to check without flooding your support inbox.

Our status pages run on separate infrastructure, so they stay up even when your app doesn't. One less thing to worry about.

SSL certificate details and expiry monitoring

SSL certificates handled

Never scramble for an expired cert

Let's Encrypt makes SSL free, but it doesn't make renewal foolproof. We monitor your certificates and alert you before they expire, so you never wake up to a browser warning screen.

We also catch chain issues and misconfigurations that cause problems on specific browsers.

Performance history dashboard

Performance tracking

Catch slowdowns before users complain

Your app feeling slow? We track response times and alert you when performance degrades. Catch that database query gone wrong or that third-party API slowing things down.

Set performance budgets and get notified when you exceed them. Great for staying on top of technical debt.

API performance monitoring

API endpoint validation

More than just HTTP 200

A 200 status doesn't mean your API is working correctly. We can validate response content and check that endpoints return expected data. When your auth endpoint returns an empty response, you'll know.

Monitor the endpoints your customers depend on, not just your marketing site.

Alerts where you already are

Slack, email, webhooks, and more

Get alerts in Slack, email, or wherever your team works. No need to check another dashboard. When something breaks, the notification finds you.

Use webhooks to trigger your own automations, restart services, or log incidents.

Frequently asked questions

Target rings Target rings

Is Oh Dear a good fit for a small SaaS or indie hacker?

Yes. You get the whole monitoring stack in one place: uptime and performance checks with no agent to install, cron and scheduled-task monitoring, application health checks for the queues and workers your product depends on, SSL and domain-expiry alerts, and a hosted status page. It is flat, founder-friendly pricing instead of enterprise tiers, so you get the coverage a paying-customer product needs without stitching together five free tools.

Why do SaaS founders choose Oh Dear over a free uptime checker?

A free checker pings your homepage and stops there. Oh Dear verifies a failure from a second location before it pages you, checks the response content so a broken signup or billing call is caught (a 200 status is not the same as working), monitors the cron jobs your product runs on, and gives customers a status page during an incident. It is the difference between knowing your marketing site loads and knowing the product works. See how we compare to UptimeRobot.

I'm pre-revenue. Is monitoring worth paying for yet?

The moment you have users who would notice an outage, yes. Silent failures, an expired certificate, a stuck queue, a checkout that 500s, cost you the exact early users and trust you can least afford to lose, and you usually hear about it from an angry tweet. Our trial is free with no credit card, so you can have real coverage in place before the first incident, not after it.

How quickly will I know when my SaaS goes down?

We check every minute from multiple global locations. The moment downtime is detected, you get an alert via Slack, email, SMS, or your preferred channel. Most alerts arrive within 60-90 seconds of an outage starting, so you know before customers start tweeting about it.

Can I monitor my background jobs and queues?

Yes. SaaS apps run on background jobs: email queues, subscription billing, data syncs, report generation. We monitor scheduled tasks and alert you when they fail or take too long. No more debugging why that email didn't go out or why subscriptions weren't renewed.

How does a status page help my SaaS?

A status page shows customers you take reliability seriously. When issues happen, it gives them a place to check without flooding your support inbox. Our status pages run on separate infrastructure, so they stay up even when your app doesn't. One less thing to worry about during incidents.

Can I monitor my API endpoints, not just my marketing site?

Absolutely. A 200 status doesn't mean your API is working correctly. Our dedicated API & endpoint monitoring validates response content and checks that endpoints return expected data. When your auth endpoint returns an empty response or your checkout API fails silently, you'll know immediately.

Is Oh Dear affordable for indie hackers and small SaaS?

Yes. We built Oh Dear to be accessible for solo founders and small teams. You get enterprise-grade monitoring without enterprise complexity or pricing. Start with our smallest plan and scale as your SaaS grows. No long-term contracts, no hidden fees.
