Comparison

UptimeClarity vs SkySignal

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.

Why teams choose UptimeClarity

Bundled uptime + status pages on every plan

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.

A free tier you don't have to outgrow in a week

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.

Meteor 2 and Meteor 3 — first-class for both

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.

Pricing that does not scale with hosts

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.

Migration in 3 steps

Switch in under 10 minutes

  1. Remove the old package. meteor remove skysignal:agent.
  2. Install UptimeClarity. meteor add uptimeclarity:agent and add your API key to Meteor.settings.
  3. Re-create alerts. Pull your alert channels into UptimeClarity — Slack, email, webhook, SMS. Done.

Install in 30 seconds

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.

1. Install
meteor add uptimeclarity:agent
2. settings.json
settings.json
{
  "private": {
    "uptimeClarity": {
      "serverKey": "uc_srv_xxxxxxxxxxxxxxxx"
    }
  },
  "public": {
    "uptimeClarity": {
      "clientKey": "uc_pub_xxxxxxxxxxxx",
      "appName": "my-app"
    }
  }
}
3. Server init
server/main.js
// 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,
  });
});
4. Client init (RUM)
client/main.js
// 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
      methods:       true, // Meteor.call latency & errors
      subscriptions: true, // pub/sub ready time + payload size
    },
  });
});
5. Run with settings
meteor run --settings settings.json

Comparison & migration FAQ

Is this comparison fair?
We aim to be accurate as of publication based on the SkySignal website, docs, and public changelog. SkySignal is a serious newcomer with a smart team, and we welcome competition. If something has changed, email us and we will update this page.
When was SkySignal launched?
SkySignal launched its public beta in December 2025 and is still labelled beta on its own site. UptimeClarity has been generally available longer and runs production workloads today.
Does SkySignal support Meteor 2.x?
No — SkySignal's documentation requires Meteor 3.0 or later. UptimeClarity supports both Meteor 2.x (Fibers) and Meteor 3.x (native async) from the same Atmosphere package.
Is SkySignal cheaper at scale?
It depends on your host count. SkySignal charges $5/host on Starter and $10/host on Pro. A 10-host production deployment hits roughly $50–$100/host/month before adding their AI add-on; UptimeClarity's Pro at $79/month covers an entire team regardless of host count, with predictable pay-as-you-go alert overages.
Does UptimeClarity have a Node SDK for non-Meteor services?
Yes. We publish a standalone Node SDK so the same dashboard covers your Express/Fastify/Hono microservices alongside your Meteor app. SkySignal is currently Meteor-only.
What about AI auto-remediation?
SkySignal advertises Astra ($100/site/month) as 'coming soon' for AI-driven auto-PR fixes. We have an open-source remediation worker (clarity-worker) on our roadmap and intend to ship a comparable workflow without the per-site surcharge.
Can I migrate from SkySignal?
Yes. The instrumentation surface is similar — methods, publications, MongoDB, jobs, HTTP, logs, RUM. Remove the SkySignal package, add ours, and copy your API key into Meteor.settings. Email us for white-glove migration help.
