Latency Test

Performance & Uptime Monitoring for APIs and Websites·latencytest.me

From $6.58/mo · Free plan See pricing ↓

Latency Test measures HTTP latency for APIs and websites, breaking each request into DNS lookup, TCP connection, TLS handshake, TTFB, and content transfer phases. It offers 24/7 uptime monitoring with alerts sent to Email, Slack, PagerDuty, or OpsGenie, plus shareable public performance reports covering 24h, 7d, 30d, or 90d windows. Monitoring data can be accessed programmatically via a REST API or queried through an MCP server from AI tools like Claude and Cursor.

What it's for

API performance debugging by isolating DNS, TLS, and application-level latencyCDN and infrastructure validation by comparing content transfer times before and after changesSRE and on-call alerting via PagerDuty or OpsGenie for latency or failure thresholdsSLA compliance tracking using historical latency and uptime data
