Recently Detected Outages
Our crowd-sourced monitoring network detects API outages in real-time from production traffic — often minutes before official status pages acknowledge the issue.
How APIdown Works
Three steps to independent, crowd-sourced API monitoring — no synthetic pings, no vendor bias.
Install the SDK
Add one line to your app. Our lightweight SDK silently reports anonymized latency and error data from real API calls.
npm install @apidown/sdkWe Detect Issues
Signals from thousands of apps feed our anomaly detection engine. We spot degradations and outages in under 30 seconds.
Get Alerted
Receive instant notifications via email, Slack, Discord, PagerDuty, or webhook — minutes before official status pages update.
Built for Developer Workflows
Crowd-Sourced Signals
Lightweight SDKs report latency and error rates from thousands of production apps — no synthetic pings required.
Real-Time Detection
Outages and degradations surface within seconds thanks to continuous signal aggregation and anomaly detection.
Instant Alerts
Get email or webhook notifications the moment an API you depend on shows signs of trouble — before the provider discloses it.
Latency Analytics
View per-region latency trends, percentile breakdowns, and 24-hour sparkline charts for every monitored API.
Why Do Developers Choose APIdown Over Official Status Pages?
APIdown is not operated by any API provider. The data comes from your peers — real developers running real workloads.
Community signals often detect problems minutes before the vendor acknowledges them. Stop refreshing their status page.
From Stripe and OpenAI to AWS S3 and Twilio — monitor the APIs your stack depends on, all in one dashboard.
The public dashboard is free with no account required. Paid plans add alerts, webhooks, custom APIs, and API access.
Frequently Asked Questions
What is APIdown and how does it work?
APIdown is a crowd-sourced, real-time API health monitoring platform. Instead of synthetic pings, it aggregates anonymized signals from real production traffic across thousands of applications to determine whether an API like Stripe, OpenAI, or AWS is actually experiencing issues. The lightweight SDK reports latency and error-rate data, and our backend uses anomaly detection to flag degradations or outages within seconds.
Is APIdown free to use?
Yes. The public status dashboard is completely free. You can view real-time status, latency trends, and incident history for all monitored APIs without an account. Paid plans unlock features like webhook alerts, custom API monitoring, and programmatic API access.
How is APIdown different from a traditional status page?
Traditional status pages are operated by the API provider and often lag behind real outages. APIdown uses independent, crowd-sourced data from actual production traffic, giving you a neutral, real-time view of API health before the provider acknowledges a problem. Think of it as "Waze for API status."
Which APIs does APIdown monitor?
APIdown monitors over 40 popular APIs across categories including Payments (Stripe, PayPal), AI/LLM (OpenAI, Anthropic), Cloud (AWS, GCP, Azure), Communications (Twilio, SendGrid), Auth (Auth0, Clerk), and more. New APIs are added regularly based on community demand.
How do I get alerts when an API goes down?
Create a free account and subscribe to any APIs you depend on. You'll receive email alerts when status changes are detected. Paid plans add webhook notifications so you can trigger automated incident responses in your own infrastructure.
Can I monitor my own custom APIs with APIdown?
Yes. Pro and Enterprise plans let you add custom API endpoints to the monitoring network. Your custom APIs benefit from the same crowd-sourced signal aggregation and alerting as the built-in catalog.
