Moonitor is a new uptime monitor, founded in London in March 2026, and it's selling a lifetime deal on AppSumo. You pay once instead of monthly. It's for founders who'd rather not add another subscription and are comfortable backing a very young product. Solo is a one-off $54 (Moonitor's own Solo plan is $14 a month), Team is $114 and Max is $199.
AppSumo is showing a 10% price cut on all three tiers until about 31 Oct 2026 (around 23:59 GMT). The deal itself has no end date.
What it can do for you
Solo covers 20 monitors checked every 60 seconds, with website and API, ping and SSL checks, all alert channels, branded status pages and response-time history. Team raises that to 100 monitors at 30-second checks and adds keyword, port, cron, DNS and domain checks. Max is unlimited. Mobile apps aren't named, but you can watch an app's backend through its API or, on Team and up, a cron heartbeat.
You need to activate within 60 days, and you can get a refund for up to 60 days.
The honest downsides
- A Radar listing. AppSumo calls Radar a discovery engine and says it doesn't check these products, so its "We Got Your Back" guarantee doesn't apply.
- Very new. Moonitor was founded in March 2026, and there are only 4 reviews on AppSumo so far.
- Key checks start on Team. Domain, cron and keyword checks aren't on Solo.
Skip it if
- you want a monitor with a long track record
- a free plan would cover what you need
Alternatives
- Better pick for most small sites: HetrixTools. It's free for 15 sites at 1-minute checks, with SSL, domain and nameserver alerts. The catch: you must log in every 90 days.
- UptimeRobot covers 50 monitors free at 5-minute checks.
