Traefik Proxy API
Traefik is a cloud-native reverse proxy and load balancer with a REST API for dynamic configuration, real-time routing introspection, and health/metrics access.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
API is insecure by default — a common misconfiguration in homelab and dev environments. No native RBAC on the API; auth is all-or-nothing via middleware. TLS for the API itself requires explicit entrypoint configuration.
⚡ Reliability
Best When
Best when you need a self-hosted, container-native reverse proxy whose live routing state can be introspected programmatically by agents or automation pipelines.
Avoid When
Avoid when you need a fully managed reverse proxy with zero operational overhead or when your use case requires runtime write mutations to routing config via API.
Use Cases
- • Query the Traefik API to enumerate all registered routers, services, and middleware for service discovery in a dynamic microservices environment
- • Poll the /health and /ping endpoints to verify Traefik availability before routing traffic or running integration tests
- • Use the dashboard API to inspect TLS certificate status and expiry across all entrypoints during automated certificate rotation workflows
- • Read active load balancer backend health status via the API to dynamically adjust upstream selections in orchestration scripts
- • Retrieve current routing rules and middleware chains via the REST API to validate configuration drift against infrastructure-as-code definitions
Not For
- • Dynamically modifying routing configuration at runtime — Traefik's API is read-only by default; writes require provider config changes
- • Replacing a full API gateway with auth, rate limiting, and developer portal features — use Kong or AWS API Gateway instead
- • Environments that need a managed SaaS reverse proxy — Traefik is self-hosted only (Traefik Hub adds SaaS features)
Interface
Authentication
The API and dashboard are unsecured by default and must be explicitly protected. Basic auth or a forward-auth middleware is the standard approach. TLS is opt-in. Never expose the API publicly without authentication.
Pricing
Core Traefik is MIT-licensed and fully free. Traefik Hub (cloud management plane) has a free tier and paid plans.
Agent Metadata
Known Gotchas
- ⚠ The API must be explicitly enabled in static config (`api: true`) — it is disabled by default and agents will receive connection refused without this
- ⚠ The dashboard API (/api/...) and the ping/health endpoints are on different paths; /ping is always available but /api/* requires api.insecure or proper auth setup
- ⚠ Router and service names in the API include the provider suffix (e.g., `my-router@docker`) — agents must strip or handle the @provider suffix when matching names
- ⚠ The API is read-only; any attempt to POST or PUT configuration changes will return 405 Method Not Allowed — dynamic config must go through a provider (file, Docker labels, K8s CRDs)
- ⚠ TLS certificate information returned by the API may lag real-time ACME state by up to one polling cycle — don't treat it as authoritative for immediate cert validity checks
