HAProxy is a fast, reliable open-source reverse proxy and load balancer for TCP and HTTP-based applications, providing high availability, TLS termination, caching, and proxying. It is written in C and widely used in production for high-performance traffic distribution.

Use cases

• load balance traffic across multiple backend servers
• terminate TLS/HTTPS for web applications
• set up a reverse proxy in front of HTTP services
• mitigate DDoS and rate-limit abusive clients
• achieve high availability for TCP services
• proxy HTTP/2 and IPv6 traffic
• cache responses at the edge

When to choose

• you need battle-tested, high-performance load balancing for TCP or HTTP
• you want TLS termination, health checks, and high availability in one tool
• you need fine-grained traffic control, ACLs, and rate limiting
• you are running production infrastructure that demands reliability

When to avoid

• you need a simple static file server or full application server
• you want a lightweight proxy for a single small service where a simpler tool suffices
• you need layer-7 features tied to a specific ecosystem like Kubernetes ingress with rich CRDs
