# ionscale > **Note**: > ionscale is currently beta quality, actively being developed and so subject to changes **What is Tailscale?** [Tailscale](https://tailscale.com) is a VPN service that makes the devices and applications you own accessible anywhere in the world, securely and effortlessly. It enables encrypted point-to-point connections using the open source [WireGuard](https://www.wireguard.com/) protocol, which means only devices on your private network can communicate with each other. **What is ionscale?** While the Tailscale software running on each node is open source, their centralized "coordination server" which act as a shared drop box for public keys is not. _ionscale_ aims to implement such lightweight, open source alternative Tailscale control server. ![GitHub Actions Workflow Status](https://img.shields.io/github/actions/workflow/status/jsiebens/ionscale/build.yaml) ![GitHub go.mod Go version](https://img.shields.io/github/go-mod/go-version/jsiebens/ionscale?label=go) ![Go Report Card](https://goreportcard.com/badge/github.com/jsiebens/ionscale) ![GitHub All Releases](https://img.shields.io/github/downloads/jsiebens/ionscale/total) ![GitHub Release](https://img.shields.io/github/v/release/jsiebens/ionscale) ⭐ If you find _ionscale_ useful, please consider giving it a star on GitHub, or [drop a note](https://github.com/jsiebens/ionscale/discussions/new?category=show-and-tell) on how you are using _ionscale_. ## Features - multi [tailnet](https://tailscale.com/kb/1136/tailnet/) support - multi user support - OIDC integration (not required, although recommended) - [Auth keys](https://tailscale.com/kb/1085/auth-keys/) - [Access control list](https://tailscale.com/kb/1018/acls/) (with support for `autogroups`, `tagOwners`, `autoApprovers`, `nodeAttrs`, `grants` ...) - [DNS](https://tailscale.com/kb/1054/dns/) - nameservers - Split DNS - MagicDNS - [Subnet routers](https://tailscale.com/kb/1019/subnets) and [Exit Nodes](https://tailscale.com/kb/1103/exit-nodes) - [HTTPS Certs](https://tailscale.com/kb/1153/enabling-https/) - [Tailscale SSH](https://tailscale.com/kb/1193/tailscale-ssh/) - [Tailscale Serve](https://tailscale.com/kb/1312/serve) - [Service collection](https://tailscale.com/kb/1100/services/) - [Taildrop](https://tailscale.com/kb/1106/taildrop/) ## Documentation Some documentation can be found [here](https://jsiebens.github.io/ionscale) ## Disclaimer This is not an official Tailscale or Tailscale Inc. project.
