Flat pricing. Per plan, not per monitor.

• Founding pricing is a limited launch offer (about 40% off list). Subscribe during launch and you keep your founding rate for as long as your subscription stays active; new subscribers pay list once the launch window closes.
• Annual billing gives you roughly two months free, on top of the founding rate.
• Prices are in euros.
• Free plan: an optional Supporter option lets you chip in to support Mortemain and get a bigger raw ping log.
• Add-on check packs are coming, so one extra check never forces a whole tier jump.
• Roles are owner / editor / read-only. Check counts are per account; retention (raw log and uptime history) is per check.

Why the cheaper-looking option isn't cheaper

You're paying for an alert you can trust.

• Signed, replay-resistant check-ins. Optional HMAC-signed pings that a sniffed or leaked URL can't replay to fake a healthy check. A real differentiator and an additional trust layer for your alerts.
• Cryptographically partitioned multi-tenancy, for stronger data security. Sensitive fields are encrypted with a per-account key, so a stolen database stays unreadable.
• An EU business, EU data. Hosted in France and Germany under an EU entity.
• A long uptime history. 90 days even on Free, up to 3 years on paid plans, so you see the pattern, not just the last few days.
