HAProxy
Pros
- + Free and open source — no metering, no feature paywall
- + 25 years of production use at very large scale
- + Strong documented performance with lean memory use
- + Transparent LTS lifecycle with published end-of-life dates
- + Layer 4 and 7, HTTP/2 and HTTP/3, gRPC, Lua and a REST API
Cons
- - File-based configuration only — no GUI in the community edition
- - No support or SLA unless you buy HAProxy Enterprise
- - Advanced security (WAF, bot management) is an enterprise add-on or DIY
- - You bring the infrastructure — no managed service in the free tier
- - Linux-first; other platforms are second-class
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
