Edge Observability
Caddy: The Observability-Native Gateway
Replace legacy Nginx boilerplate with a modern, memory-safe entry point that automates your SSL, mTLS, and OTel telemetry export.
High-Performance Edge Architecture
Why leading engineering teams are migrating to Caddy for their observability stack.
Directly export HTTP metrics and spans to your collector. No sidecars, no extra exporters, no friction.
Built in Go to eliminate buffer overflow vulnerabilities common in C-based servers like Nginx.
Change routing rules on the fly via a JSON API without ever dropping a connection or restarting the process.
Automated Zero-Trust mTLS
Internal service-to-service encryption shouldn't be a manual burden. We use Caddy and Smallstep to automate the entire PKI lifecycle.
- →Identity-Based: Certificates issued based on workload identity, ensuring every internal request is verified.
- →Instant SSL/TLS: Automatic ACME integration with Let's Encrypt ensures public endpoints never expire.
Your Migration Path
Our structured approach ensures a zero-downtime transition from legacy proxies to an observability-native gateway.
Declarative Edge Config
The Caddyfile is designed for humans. Below is a production-ready example of a reverse proxy with native tracing and structured logging enabled.
- ✓ Integrated Tracing Spans
- ✓ JSON Structured Logging
- ✓ Automatic Health Checks
// Edge Proxy + OTel Tracing
:443 {
tracing {
span_name "request {http.request.method} {http.request.host}"
}
reverse_proxy localhost:8080 {
lb_policy round_robin
health_uri /health
}
log {
