Built different.From the ground up.
Not basic synthetic monitoring bolted onto a dashboard. OTel-native intelligence that emits anomaly-scored insight packs with third-party attribution and W3C traceparent into ClickStack, Dash0, Grafana, or any OTel backend.
OpenTelemetry
Every browser check emits a rich OTLP insight pack: anomaly scores, third-party attribution, screenshot URLs, and W3C traceparent. The missing OTel data source.
Browser Monitoring
Playwright browser checks with automatic third-party dependency intelligence, Web Vitals anomaly detection, and filmstrip evidence. From 14 global locations.
Agentic RCA
AI-SRE and causal-analysis engines reason over the signals they are fed. Yorker is the front-end source of truth: attributed synthetic spans, anomaly-scored events, and W3C trace continuation, all in your backend.
Alerting
Multi-location correlation, cross-monitor dependency detection, and alert triage with full OTel context. Signal instead of noise.
API Monitoring
Unlimited HTTP checks on every paid plan. Assertions, timing breakdown, TLS inspection, and OTel insight packs from 14 global locations.
MCP Monitoring
Monitor the MCP servers your agents depend on. Yorker validates the full MCP session — handshake, tool discovery, schema-drift detection, and tool-call output — not just an HTTP 200, and emits it as standard OTLP with traceparent from 14 global locations.
Monitoring as Code
Define monitors in plain YAML, deploy with a single command. Terraform-style plan/apply. Version-controlled, CI/CD-ready, AI-assistant-friendly.
Private Locations
Monitor internal services behind your firewall. Docker container, outbound HTTPS only, at half the hosted run rate. On every paid plan.
SLO Tracking
Define error budgets on HTTP checks, browser monitors, and third-party dependencies. Burn rate alerting, SLI dashboards, and OTel metric emission.
SSL Monitoring
Certificate expiry alerts, chain validation, and TLS handshake timing built into every HTTPS check. Certificate fields emit as OTel span attributes; handshake duration emits as a separate OTel metric.
Put your first check live in one command.
Free tier includes 10,000 HTTP + MCP checks and 1,500 browser checks per month. No credit card required.
