SkySignal is a promising new Meteor 3 APM. UptimeClarity covers the same telemetry surface — and bundles multi-region uptime monitoring, hosted status pages, a Node SDK for non-Meteor services, Meteor 2 support, and a free tier you can actually live on. One dashboard. One bill. No per-host tax.

Information current as of publication, sourced from skysignal.app and the SkySignal docs. Have a correction? Let us know.
SkySignal only includes uptime monitoring on Pro, and doesn't ship status pages at all. UptimeClarity gives you multi-region uptime checks, branded status pages, and custom domains on every plan — so the same dashboard powers your APM, your alerting, and your incident communications.
SkySignal's free tier limits you to one app and 24-hour retention. UptimeClarity's free tier is 25,000 events per day, 5 monitors, a hosted status page, and 7-day retention — forever. Side projects stay on free. Production teams upgrade when they're ready, not when retention expires.
SkySignal is Meteor 3.0+ only. UptimeClarity instruments Fibers and the new async runtime correctly, so teams in the middle of a Meteor 2 → 3 migration get one consistent view across both halves of their fleet.
SkySignal bills $5–$10 per host per month — a tax on every Galaxy container, every autoscaled pod, every staging replica. UptimeClarity bills per team on event volume, so adding hosts for resilience never adds invoices.

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';
import { UptimeClarity } from 'meteor/uptimeclarity:agent';
Meteor.startup(() => {
UptimeClarity.start({
// public settings — safe to ship to the browser
clientKey: Meteor.settings.public.uptimeClarity.clientKey,
rum: {
pageTiming: true, // navigation + paint timing (LCP, FCP, TTFB)
longTasks: true, // > 50ms main-thread blocks
blazeRender: true, // Blaze template render + layout timing

subscriptions: true, // pub/sub ready time + payload size
},
});
