Caddy
Pros
- + Automatic HTTPS by default — certificate issuance and renewal built in
- + Free, Apache 2.0, single static Go binary with no runtime dependencies
- + Reverse proxy with load balancing, health checks, HTTP/2 and HTTP/3
- + On-Demand TLS for SaaS platforms issuing certs on customer domains
- + Live JSON config API plus Caddyfile; fleet-wide cert coordination via shared storage
Cons
- - Raw throughput behind Nginx at extreme concurrency
- - Smaller module ecosystem; plugins require compiling a custom binary
- - Businesses are expected to buy sponsorships ($2,999/mo+) for support
- - No SLA or contractual support from a large vendor
Traefik
Pros
- + MIT-licensed proxy with the full feature set free for commercial use — no per-service or seat charges
- + Auto service discovery from Docker, Kubernetes, Consul and others with hot-reloaded dynamic configuration
- + Automatic Let's Encrypt TLS across many hostnames, HTTP/2-3, gRPC, WebSockets, TCP/UDP routing
- + Built-in observability: Prometheus/Datadog/StatsD metrics, OpenTelemetry tracing, dashboard and API
- + Long production track record since 2016, active v3.x releases, Gateway API leadership, plugin catalog (Go + WebAssembly)
Cons
- - Commercial Hub tiers are sales-gated with no public pricing; marketplace contracts run $30,000-$50,000/year
- - Advanced auth (OIDC/JWT/OPA), WAF, multi-cluster and FIPS live behind the paid line
- - Dynamic-discovery debugging (middleware ordering, provider state) has a real learning curve
- - No vendor-published benchmarks and no uptime SLA for Hub's managed components
- - Small vendor behind the commercial product; EULA includes license-key verification for paid installs
