Meet Latency

Beta

Latency is in active beta. Anything tagged Beta or

Planned is still cooking; everything else works today.

Stuff breaks. Latency has your back, the moment it goes down and the moment it comes back up.

Most monitoring tools are great at ruining your night and terrible at ending it. They page you when something fails, then leave you refreshing a dashboard at 2 a.m. wondering if it's safe to go back to sleep. Latency closes the loop: it tells you the instant a service recovers, too. Down and up. The whole story, not just the scary half.

Wait, what's "latency"?

It's the split-second delay between asking the internet for something and getting an answer. When a service is about to fall over, that delay usually spikes first, which makes it a fantastic early warning. We named the company after the number we watch so you don't have to.

Here's the thing, though: latency was never really about the numbers. Behind every one of those milliseconds is a person. Someone reaching a service, a team, a customer, each other. The checkout that goes through. The message that lands. The call that connects. When latency climbs and a connection drops, it's people who get cut off. Keeping those connections alive is the whole point; the numbers are just how we watch over them.

What you actually get

• A heads-up before your users notice. We check your sites and services from multiple places around the world, on a tight loop. A hiccup in one region won't wake you; a real outage will.
• The all-clear, not just the alarm. Recovery is a first-class event. When it's back, you'll know. Automatically.
• "Is it them or is it me?" Answered. We track the status of the big providers your stack leans on (clouds, CDNs, payment APIs) and reconcile their official pages against our own probes, so you catch the outage they haven't admitted yet.
• Answers about any host, instantly. Drop a domain or IP into the inspector: where it lives, who runs it, whether it's healthy. No account required.

Who it's for

• You ship something people rely on. Get told first, from everywhere at once, when it wobbles, and told again when it steadies.
• You stand on other people's shoulders. Stripe, a CDN, your database host. We watch them next to you, so their bad day doesn't blindside yours.
• You're just curious. Poke at any host on the public inspector and see what we see.

How it fits together

A handful of pieces that snap together:

Piece	What it does	Jump in
Monitors	Keep watch on your sites and services from around the globe.	Monitors
Alerts	Get the right people the moment something changes, up or down.	Alerts
Status catalog	Track the big providers and call out the outages they haven't.	Status catalog
Platform primitives	Public building blocks you can call yourself: DNS, geo, host inspection, key-value.	Platform overview

Start here

• Quick Start: watch your first site in a couple of minutes
• Platform primitives: the public APIs, ready to curl right now
• Grab the iOS app or install the CLI

Quick questions

Do I need an account?

Not to explore. The public platform primitives are open, no sign-up: DNS, geo, host inspection, the status catalog. An account is where your own monitors, alerts, and dashboards live.

Is it open source?

The backend isn't (yet), but our CLI is, under MIT.

Why not just use Datadog or Grafana?

Those are big observability suites for instrumenting your own code. Latency is laser-focused on the network-and-dependency question: is it reachable, is it fast, and is the thing it runs on having a bad day? Need deep app tracing? Reach for a full platform. Need to know your stack is up, and hear about it first? That's us.

Ping and traceroute already exist.

And we use them! The difference is we remember the results, connect the dots across providers, and actually tell you when something changes. That's the part a one-off command can't do.
