# Built different. From the ground up.

The front-end intelligence layer your OTel stack is missing.

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.

## Intelligence

The signals that make synthetic monitoring a first-class OTel data source: anomaly scoring, dependency attribution, and trace continuity that flow straight into your own backend.

### OpenTelemetry

The missing OTel data source. Every browser check emits a rich OTLP insight pack: anomaly scores, third-party attribution, screenshot URLs, and W3C traceparent.

[/features/opentelemetry](/features/opentelemetry)

### Browser Monitoring

Playwright browser checks with automatic third-party dependency intelligence, Web Vitals anomaly detection, and filmstrip evidence. From 14 global locations.

[/features/browser-monitoring](/features/browser-monitoring)

### 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.

[/features/agentic-rca](/features/agentic-rca)

### Alerting

Correlation, not noise. Multi-location correlation, cross-monitor dependency detection, and alert triage with full OTel context. Signal instead of noise.

[/features/alerting](/features/alerting)

## Platform

The check types and delivery surface: HTTP, MCP, browser, and private-network monitoring, defined as code, with SLOs and certificate intelligence baked in.

### API Monitoring

Unlimited HTTP checks on every paid plan. Assertions, timing breakdown, TLS inspection, and OTel insight packs from 14 global locations.

[/features/api-monitoring](/features/api-monitoring)

### 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.

[/features/mcp-monitoring](/features/mcp-monitoring)

### Monitoring as Code

Git-native monitors. Define monitors in plain YAML, deploy with a single command. Terraform-style plan/apply. Version-controlled, CI/CD-ready, AI-assistant-friendly.

[/features/monitoring-as-code](/features/monitoring-as-code)

### Private Locations

Monitor internal services behind your firewall. Docker container, outbound HTTPS only, at half the hosted run rate. On every paid plan.

[/features/private-locations](/features/private-locations)

### SLO Tracking

Error budgets on synthetics. Define error budgets on HTTP checks, browser monitors, and third-party dependencies. Burn rate alerting, SLI dashboards, and OTel metric emission.

[/features/slo-tracking](/features/slo-tracking)

### SSL Monitoring

Certificate intelligence. 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.

[/features/ssl-monitoring](/features/ssl-monitoring)

## 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.
