- you require instant alerts on security incidents
- you run multiple web apps and need rule‑based security rules
Choose AdGuard Home if…
- you need network‑wide ad blocking without client‑side
- you want DNS‑over‑TLS or DNS‑over‑HTTPS for encrypted
- you have a Raspberry Pi or similar low‑cost box to host a
- you prefer a web UI over CLI‑only configuration
- you need an open‑source, free solution for a small office

How to Decide
frp is a fast, open‑source reverse proxy used by developers and IT professionals for NAT traversal and firewall bypass. The alternatives split into a few clear camps: SafeLine leans into built‑in web‑application firewall protection with real‑time traffic monitoring and alerting; Traefik emphasizes zero‑config service discovery and automatic TLS certificate provisioning for cloud‑native environments; ExpressVPN is a commercial VPN offering a large global server network and proprietary Lightway protocol; rathole focuses on high‑performance Rust‑based proxying with built‑in WebSockets and gRPC support; NPS targets intranet penetration with a lightweight design and a browser‑based management console.
When choosing a replacement for frp, the key factors that actually differentiate the options are: how TLS and encryption are handled (manual configuration in frp versus automatic Let’s Encrypt in Traefik or built‑in SSL in rathole); the presence of additional security or monitoring layers such as WAF rules and real‑time alerts in SafeLine or traffic dashboards in NPS; performance and language runtime, since Rust‑based rathole promises higher throughput than Go‑based peers; the pricing model, notably the free‑only nature of most alternatives versus ExpressVPN’s subscription cost; and the availability of a graphical or web‑based management UI, which frp lacks but NPS and Traefik provide to varying degrees.
