frp vs Traefik Proxy

frp is a free, self-hosted reverse proxy for making intranet services reachable from the public network through nodes with public IP addresses. It supports TCP, UDP, HTTP, and HTTPS proxying, while client-server communication also supports QUIC, KCP, WebSocket, and other protocols. Its XTCP mode uses P2P hole punching so successful connections send traffic directly rather than through frps, but success depends on the network’s NAT type and cannot be assured. Client and server authentication support tokens and OIDC, with token authentication as the default; encryption is among the project’s listed capabilities. Proxy groups can balance load, and TCP or HTTP health checks can remove failed services from frps. Monitoring can run in memory or through Prometheus, which requires the Dashboard to be enabled. frps has a browser Dashboard for status and proxy statistics, while frpc includes an Admin UI for proxy status and configuration. Configuration supports TOML, YAML, and JSON; INI is still supported but no longer recommended. Written in Go, frp provides platform-specific binaries for cross-platform deployment without additional dependencies. The project is under development and says version 2 will not be compatible with version 1.

Traefik Proxy is a free, open-source reverse proxy and ingress controller for deploying services and APIs. It discovers services and adjusts routing dynamically, supporting HTTP, HTTP/2, HTTP/3, TCP, UDP, WebSockets, and gRPC. Traffic controls include Layer 4 and Layer 7 routing, mirroring, blue-green and canary deployments, stickiness, and active health checks. Security options include automatic HTTPS, Let’s Encrypt, custom certificates, authentication, and Web Application Firewall support. Integrations span Kubernetes, Docker, Docker Swarm, Red Hat OpenShift, Rancher, Amazon ECS, Consul, and key-value stores. It supports deployment on environments including Kubernetes distributions, virtual machines, bare metal, Docker Swarm, and HashiCorp Nomad. Observability includes OpenTelemetry, a built-in dashboard, distributed tracing, and metrics integrations. WebAssembly plugins and a public plugin catalog provide extension options. Traefik Proxy is self-hosted and listed for Linux, macOS, and Windows. The plan is free; Traefik Labs also offers commercial support with expert assistance available 24/7/365.
