Where UptimeClarity is different

Built for Meteor 3 from day one

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.

APM, uptime, status pages & RUM in one place

When the pager goes off you don't want to bounce between tools. Same alert routing, one billing line, one source of truth — and Core Web Vitals from real users in the same dashboard.

Predictable, modern pricing

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.

Migration in 3 steps

Switch in under 10 minutes

Remove the old package. meteor remove montiapm:agent (or your existing instrumentation).
Install UptimeClarity. meteor add uptimeclarity:agent and add your API key to Meteor.settings.
Re-create alerts. Pull your alert channels into UptimeClarity — Slack, email, webhook, SMS. Done.

Stuck? Email [email protected] and we’ll help you switch live, free of charge.

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. Monti APM is a respected tool that powered Meteor monitoring for many years. If you spot something out of date, email us — we update this page when their feature set changes.

How long does migration take?

Typically under 10 minutes. Remove the Monti package, add the UptimeClarity Atmosphere package, and copy your API key into Meteor.settings. Your historical data stays where it is.

Will my dashboards look the same?

The mental model is identical — methods, publications, traces, MongoDB. The presentation is more modern (dark-first, parallax-free, fluid layouts) and includes uptime + status pages so you don't need a second tool.

Can I run both side-by-side during evaluation?

Yes. Both agents are designed to be lightweight and unobtrusive; running both during a one-week evaluation is perfectly safe.

What about my existing alert routing?

You can recreate the same alerts in UptimeClarity in minutes — webhooks, Slack channels, and email distribution lists work the same way. SMS is included on Pro and above.

Is there a discount for switching?

Yes — contact sales with proof of an active Monti APM subscription and we will credit one month of Pro to your account.

Ready to try it?

Free forever plan. 30-second install. If you're coming from Monti APM, mention it and we'll credit a month of Pro.
