SoftEther is the university project that became one of the most capable VPN servers you can run for free: an open-source, multi-protocol VPN program from the University of Tsukuba, licensed under Apache 2.0 and free for personal and commercial use. It speaks OpenVPN, Microsoft SSTP, L2TP/IPsec and its own SSL-VPN protocol, so almost any device you own -- Windows, macOS, Linux, FreeBSD, Solaris, plus iOS and Android clients -- can dial in without buying a Windows Server license. The tutorial videos that keep it relevant are home-server ones: a Windows machine, an evening, and your own VPN reachable from anywhere. That matters because in a category now dominated by subscription apps, a free server you own is a different proposition entirely. A VPN server you administer yourself also means the logs, the keys and the policies stay on hardware you control. Reviewers demonstrate the full loop on camera: install, create a user, connect from a phone outside the network, and browse back through home.
What it does well
Every protocol in one server: OpenVPN cloning for a smooth migration, native SSTP and L2TP/IPsec for phones and laptops, and SoftEther's own SSL-VPN built to punch through firewalls with low latency -- one server, every client covered. The project frames this as its core argument: whatever device walks in the door, there is a protocol it already speaks.
It works where VPNs usually struggle: built-in NAT traversal and firewall-resistant design mean a server behind a home router or a fussy corporate network stays reachable.
Genuinely free and open: Apache-licensed source code, no feature gates, and a university-backed project that has outlived several commercial competitors.
Who it's for
SoftEther fits homelab builders who want their own remote access, small businesses enabling BYOD without per-seat VPN licensing, and anyone replacing an aging OpenVPN setup -- the clone function migrates existing configs rather than forcing a rebuild. Remote teams get the same deal: laptops and phones connect with the clients they already ship. Tinkerers who enjoy a full management console will feel at home; it is a server product, not a one-click app. The setup videos walk it start to finish in under twenty minutes, which sets expectations honestly.
Where it falls short
The interface shows its academic age: the management console is dense, and setup involves more steps than the new wave of consumer VPN apps -- reviewers recommend changing the dynamic DNS hostname early and saving often. Give it an evening and a backup of the config, and the complexity becomes manageable.
Documentation is deep but dated: the wiki answers nearly everything, though not always in the order a newcomer asks. The how-to guides for each client platform are the pages worth bookmarking.
WireGuard is not on the menu: newer protocols get hype for good reason, and WireGuard users will not find it here. For everything else -- legacy clients, restrictive networks, mixed device fleets -- the coverage is the reason people still install it.
