Monti APM is a great tool that has supported the Meteor community for years — this page is here to help you decide if UptimeClarity is the right fit for your team. Our edge: native Meteor 3 async, reactive observability (LiveQuery driver mix + observer leak detection + MongoDB pool tracking), background-job monitoring, app logs, uptime, and hosted status pages — all in a single dashboard.

See your LiveQuery driver mix per collection in real time, catch leaking observers before they take down your app, and watch your MongoDB connection pool drain — all on one screen. The signals that actually break long-running Meteor servers, finally observable.
Meteor 3 is a fundamental shift away from Fibers toward native async. UptimeClarity instruments the new runtime correctly — your async/await stacks stay intact and timings stay accurate.
When the pager goes off you don't want to bounce between tools. Methods, publications, MongoDB, sjobs, outbound HTTP, app logs, uptime monitoring, status pages, and Core Web Vitals — same dashboard, same alert routing, one bill.
A generous free tier, plain monthly plans, and pay-as-you-go overages on Pro — so a traffic spike never turns into a billing emergency.

A single package on the server, no agents or sidecars. Server APM and browser RUM share the same dashboard.
Two keys, two scopes. The uc_srv_ server key stays on the server. The uc_pub_ public key is safe to ship to browsers — it only accepts RUM events from origins you allow-list.
meteor add uptimeclarity:agent{
"private": {
"uptimeClarity": {
"serverKey": "uc_srv_xxxxxxxxxxxxxxxx"
}
},
"public": {
"uptimeClarity": {
"clientKey": "uc_pub_xxxxxxxxxxxx",
"appName": "my-app"
}
}
}// server/main.js
import { Meteor } from 'meteor/meteor';
import { UptimeClarity } from 'meteor/uptimeclarity:agent';
Meteor.startup(() => {
UptimeClarity.start({
// private settings — never reach the browser
apiKey: Meteor.settings.private.uptimeClarity.serverKey,
appName: Meteor.settings.public.uptimeClarity.appName,
});
});// client/main.js
import { Meteor } from 'meteor/meteor';
