WatchDog's Free plan keeps a single URL or hostname alive with email alerts and a private status page. Upgrade to Pro for unlimited monitors, Slack + webhook channels, tags, public status pages, test-alert channels, and scheduled maintenance windows. Cancel any time — no contract.
Slack alerts delivered in under 5 seconds. Webhook payloads signed with HMAC for your infra to verify. A Test button on every channel so you confirm delivery before a real incident — not during one.
Share a /status/<slug> URL from your docs or site footer. Live SVG uptime badge you can drop into a README. Replaces "is it down?" support tickets with a page your users open before they ping you.
A Send-Test button on every channel — Slack, webhook, email, SMS. Confirm the alert format in seconds and stop finding out your webhook URL is wrong at 2am.
Slice 200 monitors by client, environment, or owner in one click. Tags double as alert routing — a "staging" tag routes to a different Slack channel than "production".
Pre-announce deploys, freezes, and migrations in 30 seconds. Alerts pause inside the window, your status page flips to "scheduled maintenance" — your customers see the planned work instead of an incident at 2am.
A real reply within a business day from the team that built WatchDog. Skip the community queue when your monitoring is the thing that's broken.
For hobby projects and solo builders.
For teams shipping customer-facing services.

Pro is billed monthly at $19/month through Stripe. There is no annual lock-in or contract — your subscription renews each month and you can cancel any time from the Billing page. Cancellation takes effect at the end of the current billing period, so you keep Pro features until then.
WatchDog offers a 14-day refund window on Pro subscriptions. If Pro is not a fit within your first two weeks of paid access, contact support and we will process a full refund — no usage conditions, no questionnaire.
The Free plan covers 1 monitor — perfect for a single URL, hostname, or status-page probe. Pro unlocks unlimited monitors, so you can run every production endpoint, every staging environment, and every client URL through one WatchDog account without hitting a cap.
It sends a sample notification through any configured channel — Slack, webhook, email, or SMS — using the same payload format and routing as a real incident. Run it whenever you add or change a channel to confirm the alert format and delivery land correctly before a real outage, instead of finding out a webhook URL is wrong at 2am.
Pro adds Slack and webhook alert channels (Free is email-only), per-monitor tags with filtering, unlimited status-page monitors (Free is capped), test-alert channels on every endpoint, scheduled and recurring maintenance windows, and priority email support with a one-business-day reply from the WatchDog team.
Upgrading is self-serve. If you are signed out, the Upgrade button takes you to the Stripe checkout. If you are signed in on Free, it opens /billing/upgrade to start the same checkout. If you are already paid, /billing opens your manage-subscription page. Downgrading to Free keeps your account, your monitor history, and your alert preferences intact — the Free-plan monitor cap simply applies again.
WatchDog's free plan solves one URL with email alerts. Pro is everything else — Slack and webhook channels, tags, public status pages, scheduled maintenance windows, test-alert channels, and a team that replies within a business day.
