Show HN: Holesail – Share localhost over peer-to-peer, no port forwarding
holesail.io
Wanted to share a project I have been building for a while: Holesail, a lightweight peer-to-peer tunneling tool that makes sharing local self-hosted services extremely easy.
No port forwarding, no VPNs, no servers in the middle — just a direct, end-to-end encrypted connection between two peers using a simple connection key.
It supports both UDP and TCP and runs on Linux, Mac, Windows, Android and iOS.
The goal is to make Holesail the go-to solution for developers, hobbyists, and teams who need fast, reliable, private connectivity: hosting dev servers for teammates, sharing localhost, enabling LAN-style multiplayer, remote access, SSH, self-hosting or P2P features in applications without managing networking complexity.
It is the perfect alternative to Tailscale and Cloudflared.
Would love to hear feedback from anyone working with networking, P2P systems, or tunneling tools.
Happy to answer any questions!
Thanks
