Know when
your APIs
go down.
Add your endpoints. We ping them every 5 minutes, record response times, and fire an alert the moment something breaks — before your users ever notice.
Built by a developer tired of finding out about downtime from users, not alerts.

Instant Push Notifications
The moment a monitor goes down, you know. Browser push notifications and webhook POSTs fire immediately on status change.
Response Time Tracking
Every ping records latency. Color-coded readouts instantly show what's fast, degraded, or broken.
Public Status Pages
One shareable link. Your users see live status, uptime %, and auto-refreshing data. Zero setup.
Add your endpoints
Paste any URL — REST APIs, health checks, webhooks, staging environments. Takes 10 seconds.
We ping every 5 minutes
Our worker hits each endpoint on schedule, recording the status code and latency every single time.
Get alerted instantly
The second something breaks — or recovers — you get an alert. Not a minute later. Not 5 minutes later.

Create free accountQuestions & Answers
Is this really free?
Yes, completely free. No credit card required, no trial period. Free tier includes 5 monitors, 5-minute check intervals, push notifications, webhooks, and a public status page. We plan to offer a paid tier in the future for teams that need more — but the free tier stays free forever.
How do I get notified when something goes down?
Pulse supports browser push notifications — just click the bell icon on your dashboard and allow notifications. You can also add a Discord webhook URL to any monitor and get a formatted alert directly in your Discord server.
What happens if I exceed 5 monitors?
You'll see a message letting you know you've hit the free tier limit. We're working on a Pro plan for unlimited monitors — stay tuned.
How accurate is the uptime data?
Pulse pings your endpoints every 5 minutes from our worker server. Response time and status code are recorded on every check. This means downtime shorter than 5 minutes may not be detected — longer intervals are a Pro tier feature.
Is my API data private?
Yes. Each user can only see their own monitors and ping history. Your endpoint URLs are never shared or exposed to other users.
Can I share my uptime with my users?
Yes — every account gets a public status page at your Pulse URL /status/your-id. Share the link with your users or clients so they can see live uptime without needing an account.
