3X-UI vs OpenVPN Access Server
Both tools provide a web panel for administering VPN or proxy servers with per-client access controls. The key differences are protocol depth, licensing cost, and DPI circumvention capability.
| Feature | 3X-UI | OpenVPN Access Server |
|---|
| License | GPL-3.0 | Proprietary |
| Free tier | Unlimited (self-hosted) | 2 simultaneous connections |
| Protocols | VLESS, VMess, Trojan, WireGuard, Hysteria2, and more | OpenVPN, WireGuard |
| Multi-node | Yes | Limited in standard tiers |
| DPI circumvention | Yes (REALITY, XTLS, AmneziaWG) | No |
| Subscription links | Yes (VLESS, Clash, JSON) | No |
| Vendor support | Community | Paid plans available |
3X-UI is the better choice when protocol flexibility or DPI circumvention matters. REALITY, XTLS-Vision, and AmneziaWG are specific to the Xray-core ecosystem and are not available in any commercial panel at any price tier. For operators who need to support many different client apps via subscription links, 3X-UI has no commercial equivalent in that feature set.
OpenVPN Access Server is worth choosing when your environment standardizes on OpenVPN clients, your organization requires enterprise SLA support, or you need a vendor to provide compliance documentation. Its paid tiers include official support contracts that 3X-UI, as a community-maintained project, does not offer.
3X-UI vs Pritunl
Pritunl is a self-hosted VPN server panel with a commercial cloud management tier. Like 3X-UI, the base install runs on your own infrastructure; unlike 3X-UI, its protocol support covers OpenVPN and WireGuard only.
| Feature | 3X-UI | Pritunl |
|---|
| License | GPL-3.0 | AGPL-3.0 (open), proprietary (cloud tier) |
| Protocols | 15+ via Xray-core | OpenVPN, WireGuard |
| Multi-node | Yes, built-in | Yes, via paid cloud tier |
| DPI circumvention | Yes | No |
| Subscription output | Yes (VLESS, Clash, JSON) | No |
| Vendor support | Community | Paid plans available |
Pritunl fits teams already running OpenVPN or WireGuard who want a polished server management interface and optional commercial support. 3X-UI fits operators who need the broader Xray-core protocol set or require circumvention capabilities that Pritunl cannot provide.
