WebSocket Monitoring for Real-Time Services
WS and WSS handshake verification, latency tracking, and instant alerts
Monitor your WebSocket endpoints with full handshake checks. Track connection latency, catch upgrade failures, and get alerted when your real-time services go down. Free on both tiers.
Key Features
Everything you need to monitor your infrastructure effectively
WS & WSS Handshake Checks
Verify WebSocket connections by performing a full handshake. Detect failures in the HTTP upgrade, TLS negotiation, and protocol switch.
Connection Latency Tracking
Measure how long it takes to establish a WebSocket connection, broken down by DNS, TCP, TLS, and handshake phases.
SSL Certificate Monitoring
WSS endpoints get automatic SSL certificate validation, expiration alerts, and security checks included with every check.
Smart Failure Detection
Automatic 30-second re-checks on first failure. Alerts only fire after consecutive failures to eliminate false positives from transient issues.
Multi-Region Monitoring
Test WebSocket connections from US Central, Europe West, and Asia Southeast to catch region-specific connectivity issues.
Real-Time Alerts
Get notified instantly via email, SMS, Slack, Discord, or any webhook when your WebSocket endpoints fail.

Technical Details
Built for developers, by developers
Architecture
WebSocket monitoring runs on the same multi-region infrastructure as all exit1.dev checks. Each check performs a complete WebSocket handshake including the HTTP upgrade request and 101 Switching Protocols response. For WSS endpoints, the TLS negotiation is timed separately. Results include full connection phase breakdown and SSL certificate analysis.
Performance
WebSocket handshake checks execute quickly with minimal overhead. The connection is closed immediately after successful handshake verification. Strict URL validation ensures only valid WebSocket URLs are accepted. Process-level timeouts prevent hung connections from affecting other checks.
API
WebSocket checks are fully supported through the exit1.dev REST API. Create, update, delete, and query WebSocket monitors programmatically. Access check history, connection times, and SSL data via API endpoints. HMAC authentication with rate limits of 1000 requests/hour per key.
