Instatus is a status-page product. SiteDownCheck is a monitor that comes with a status page. The overlap is real, but the starting points differ, and that decides which one fits. If you are searching for an Instatus alternative, here is a plain comparison from a much smaller service.
Instatus facts come from its own site at the time of writing (October 2026). We did not see plan details, custom-domain or subscriber information on the page we read, so check their pricing page for those. Our facts come from our pricing page.
What each one is
Per its site, Instatus lets you publish service status publicly or privately, run incidents with a team, integrate with tools such as Slack and Teams, and it mentions monitoring with availability and performance tracking and alerts. It lists a "Free forever plan" with no card. Whether monitoring is part of the free plan was not stated on the page we read.
SiteDownCheck is an uptime monitor first. The free plan has 3 monitors at 5-minute intervals, a public status page with 30-day history, maintenance windows, badges, and alerts by email, webhook, Slack and Discord. The status page can reflect monitor results.

Where Instatus is stronger
- Communication workflow. A product designed around incidents, team updates and audience-specific pages generally has a deeper workflow than a monitor with a page attached.
- Private pages. Internal status for staff or specific customers is something we do not offer.
- Polish and focus. If the status page is itself part of your brand, a dedicated product gives more design and process options.
- Integrations in the incident flow, such as Slack and Teams, are part of its pitch.
Where SiteDownCheck fits better
- Automatic from checks. Our status page is fed by actual monitors, so it reflects reality even if nobody remembers to update it. For small teams that is a practical advantage.
- One free account for both. Monitoring, SSL and domain expiry alerts and the page together, with no extra integration to wire up.
- Low noise. A single failed check does not open an incident; we re-check first, which keeps your public page from flapping.
- Cheap to start. You can publish a page in minutes without a card.
Who should choose what
Choose Instatus if the page is a customer-facing product in itself: you need private audiences, structured incident communication and team workflows.
Choose SiteDownCheck if you want a public page that updates from monitoring and you have a small number of services.
A page is only as useful as the habits behind it. Read status page communication templates and the website status page guide for what to say and when, whichever tool you use.
One caution about where you host a status page
Do not host your status page on the infrastructure it reports on. If your site and the page share a server, a DNS provider or a CDN account, an outage can take both down at once. Use a separate provider and a separate domain or subdomain path, such as status.example.com pointing at an external service.
Migration steps
- Make a list of components on your current page: web app, API, payments, email, and so on.
- Create monitors in uptime-monitor for the ones that map to a public URL. Three on the free plan.
- Build the page in status-page and decide which monitors it shows.
- Write a short note about how customers can get updates if subscriptions differ from your old setup.
- Update links in your footer, support docs and email signatures. If you use a CNAME, lower the TTL first. See TTL explained.
- Keep the old page live for a few days with a banner pointing at the new one.
- After an incident, use the postmortem generator to publish a summary.
Honest limitations of ours
Three monitors on the free plan limits how many components you can reflect automatically. No private pages, no audience-specific views and a lighter incident workflow. We are new and small; Pro has no price or date.
Next steps
- Create a status page for your main services.
- Add a status widget to your site footer.
- Read status page communication templates.
- Write an incident postmortem.
- Review the website status page guide.
FAQ
Is SiteDownCheck a replacement for Instatus?
