Know when your API goes down. Before your users do.
Monitor your endpoints automatically, validate response payloads and JSON assertions, track SSL certificate health, and get notified instantly.
Everything you need for API Uptime & Health
Synthetic endpoint checks, deep payload assertions, SSL tracking, and instant multi-channel alerts.
Synthetic Health Checks
Continuously probe REST endpoints with configurable intervals, HTTP methods (GET, POST, PUT, DELETE), custom headers, and query parameters.
Response & JSON Assertions
Ensure your endpoints return valid data. Test payload strings and traverse JSON responses using dot-notation key/value rules.
Latency & SLA Tracking
Measure round-trip response times in milliseconds and configure maximum latency thresholds to detect degraded APIs before outages occur.
SSL Certificate Monitoring
Automatically inspect TLS peer certificates, monitor days remaining, and receive proactive warnings before certificates expire.
Instant Incident Alerts
Receive immediate email alerts when an endpoint goes down, violates SLAs, or recovers, complete with exact error causes.
Webhooks & Outage Logs
Dispatch HMAC-signed JSON alerts to Slack, Discord, or custom systems, with complete historical incident logs and uptime metrics.
Four Steps to Complete Coverage
Add API Target
Enter your target endpoint URL and select the HTTP method (GET, POST, PUT, DELETE, PATCH).
Configure Rules & SLA
Define expected status codes, JSON payload assertions, maximum latency thresholds, and check frequency.
Automated Execution
Fawru's worker engine securely pings your APIs continuously with SSRF protection and non-blocking concurrency.
Get Alerted
Receive instant updates when target APIs encounter outages, latency degradation, assertion failures, or SSL expiry.
Simple, Transparent Pricing
Choose the frequency and monitor count that suits your application needs.
