When your app breaks, the first question is always: is it us, or is it them?
If you depend on GitHub, AWS, Discord, Stripe, Cloudflare, or any major third-party service, you've probably wasted hours debugging your own code only to find out the service was down the whole time.
There's a free API for this. Let me show you how to use it.
Meet DownStatus
DownStatus is a free, public JSON API that gives you real-time status for 90+ popular services — no API key required.
curl https://isitdownstatus.com/api/status/github
Response:
{
"service": "github",
"status": "operational",
"updated_at": "2026-05-11T08:00:00Z"
}
That's it. No signup, no tokens, no rate limit headers to parse.
Practical use cases
1. Show a banner when a dependency is down
async function checkGitHubStatus() {
const res = await fetch('https://isitdownstatus.com/api/status/github');
const data = await res.json();
if (data.status !== 'operational') {
showBanner(`GitHub is currently ${data.status}. Some features may be unavailable.`);
}
}
2. Skip CI/CD steps when upstream is down
#!/bin/bash
STATUS=$(curl -s https://isitdownstatus.com/api/status/github | jq -r '.status')
if [ "$STATUS" != "operational" ]; then
echo "GitHub is $STATUS — skipping deployment"
exit 0
fi
# continue with deployment...
3. Alert your team proactively (Node.js + Slack)
const SERVICES = ['aws', 'github', 'stripe', 'cloudflare'];
async function checkAll() {
for (const service of SERVICES) {
const res = await fetch(`https://isitdownstatus.com/api/status/${service}`);
const { status } = await res.json();
if (status !== 'operational') {
await notifySlack(`⚠️ ${service} is ${status}`);
}
}
}
// Run every 5 minutes
setInterval(checkAll, 5 * 60 * 1000);
4. Python health check script
import requests
SERVICES = ['aws', 'discord', 'github', 'stripe']
def check_dependencies():
issues = []
for service in SERVICES:
r = requests.get(f'https://isitdownstatus.com/api/status/{service}')
data = r.json()
if data['status'] != 'operational':
issues.append(f"{service}: {data['status']}")
return issues
if __name__ == '__main__':
problems = check_dependencies()
if problems:
print("Upstream issues detected:")
for p in problems:
print(f" - {p}")
else:
print("All services operational ✓")

Why I built this
Debugging "is it us or them?" is a universal dev experience. Every monitoring tool I found either required signup, had rate limits, or cost money. DownStatus is just a clean, free JSON endpoint — nothing more.
Check out isitdownstatus.com and let me know if you find it useful. PRs for adding more services are welcome!
