what you give up by leaving Instatus
- Deliverability someone else warms up and monitors: your first incident email is also your first send reputation test
- Notification channels beyond email: SMS, Slack app, Teams, Discord, native webhooks, RSS, all of which Instatus ships out of the box
- Per-component subscriptions, unsubscribe handling, and double opt-in that you do not have to think about
- The polish: scheduled maintenance windows, incident templates, timezone handling, embeddable widgets, public API
- Real independence, unless you actually do the work to host the page away from your own stack
None of the picks above covers all of it. The full verdict says which gaps matter.

why people still pay for Instatus
Because a status page is the one page that must work when nothing else does, and paying a third party is the cheapest way to buy that independence. It is also a page customers and auditors look at, so it being slightly ugly or slightly late costs more trust than the subscription costs money. Most teams that build their own end up with a page that is technically theirs and practically unmaintained, with an incident feed whose last entry is from fourteen months ago.
