Top 23 FRP Open-Source Projects
-
frp
A fast reverse proxy to help you expose a local server behind a NAT or firewall to the internet.
Project mention: Wiredoor VS frp - a user suggested alternative | libhunt.com/r/wiredoor | 2025-04-26While frp is a flexible and lightweight reverse proxy solution, Wiredoor focuses on secure service exposure using modern technologies like WireGuard and NGINX as core components. Wiredoor eliminates the need for manual port forwarding or public IPs by creating a VPN-based reverse tunnel, providing better encryption, automatic HTTPS, and easier service publishing.

InfluxDB
InfluxDB high-performance time series database. Collect, organize, and act on massive volumes of high-resolution data to power real-time intelligent systems.
-
rathole
A lightweight and high-performance reverse proxy for NAT traversal, written in Rust. An alternative to frp and ngrok.
Another point to make is that the SSH tunnel technique is most suitable for temporarily exposing services for demo purposes. For permanent tunnels, you would need to add autossh to keep the connection alive, but there are better tools for permanent tunnels, such as rapiz1/rathole or fatedier/frp.

reflex
Interactive programs without callbacks or side-effects. Functional Reactive Programming (FRP) uses composable events and time-varying values to describe interactive systems as pure functions. Just like other pure functional code, functional reactive code is easier to get right on the first try, maintain, and reuse. (by reflex-frp)

Project mention: Firefly, the easiest using and high performance WireGuard VPN server | news.ycombinator.com | 2025-03-19

reflex-dom
Web applications without callbacks or side-effects. Reflex-DOM brings the power of functional reactive programming (FRP) to the web. Build HTML and other Document Object Model (DOM) data with a pure functional interface.
-
Still working on Connet[1] and the associated Connet.dev[2], which is a p2p reverse proxy with NAT traversal (and hosted version of it). Currently, adding support for defining multiple points of ingress, next will be adding support for PCP port forwarding.
