Your checks, at a glance

List every uptime monitor and its current state without opening another tab. Human-readable tables are the default; structured output is one flag away.

Monitoring belongs in your workflow

Create and update checks alongside the code they protect. Configure methods, regions, timeouts, headers, alert priority, and notification integrations from scripts or CI.

Built to compose

Add --json to feed check data into jq, deployment scripts, or your own tooling. The CLI stays explicit and scriptable instead of hiding behavior behind an interactive dashboard.

onlineornot checks list --json | jq '[.[] | select(.status != "UP")]'

[
  {
    "id": "1oaVAq6R",
    "name": "Webhooks",
    "url": "https://hooks.example.com/status",
    "status": "DOWN",
    "check_type": "UPTIME",
    "last_queued": "2026-08-25T10:42:00.000Z"
  }
]

Your next check is one command away

Make uptime part of the way you ship.
