3X-UI is the most popular open-source Xray management panel, providing a full-featured web interface for deploying and monitoring proxy and VPN protocols on Linux servers. The Go backend manages Xray-core instances supporting VLESS, VMess, Trojan, Shadowsocks, WireGuard, Hysteria2, HTTP, SOCKS, Dokodemo-door, and TUN inbounds across TCP, mKCP, WebSocket, gRPC, HTTPUpgrade, and XHTTP transports secured with TLS, XTLS Vision, and REALITY. The Clients page tracks each user with individual traffic quotas, expiration dates, concurrent connection limits, and live online status indicators, while one-click share links, QR codes, and a built-in subscription server distribute configurations in multiple output formats. The multi-node architecture manages and scales deployments across multiple servers from a single panel instance. The Panel Settings page configures listen address, port, URI path, session duration, trusted proxy CIDRs, authentication, and Telegram bot integration for remote monitoring and management alerts. Outbound routing supports WARP, NordVPN, custom rules, load balancers, and proxy chaining. Xray Configs provides template-level control over the core configuration, while the API Docs page exposes a complete RESTful API with in-panel Swagger documentation. Data persists in SQLite by default or PostgreSQL for larger deployments, with database export and import from the panel. Fail2ban integration enforces per-client IP limits. On RepoCloud, deploy 3X-UI on a dedicated VPS with Docker, root SSH access, and complete control over your proxy infrastructure, all under the GPL-3.0 license.

Running a VPN for family, friends, or a small team usually means babysitting servers one SSH session at a time, and Mistgate replaces that with one panel that keeps the whole fleet configured. Add a server from the browser by typing its address and root password: the panel pins the host key, checks the host, opens the ports, and installs the signed node agent for you. Each person gets one subscription link that their app turns into the server list, or a personal AmneziaVPN key per device, so a lost phone can be revoked without touching anyone else. Groups decide which protocol profiles a person receives, while per-user traffic quotas, expiry dates, device limits, and per-device speed limits keep sharing fair. Hysteria2 brings QUIC-based speed with port hopping, obfuscation, and certificate options; VLESS REALITY and AmneziaWG 2.0 and 3.1 cover networks where one protocol gets blocked, and Cloudflare WARP can serve as the exit for all three. Every five minutes the panel connects to each server the way a real client app would, a doctor on every node runs host checks with safe fixes, and alerts reach you on Telegram before your users notice. The public address shows strangers a decoy site while the admin hides behind a secret path, and encrypted backups go to your Cloudflare R2 bucket on a schedule.

Game servers, home labs behind carrier-grade NAT, and services that need a presence in another region all end up needing the same thing: a cheap entry machine that forwards traffic to the real backend, with rules you can change without opening an SSH session. Relay Panel is the control room for that job, a self-hosted web panel that runs TCP and UDP forwarding across a fleet of lightweight relay nodes from one dashboard. Each rule can fan out to multiple targets with failover or round-robin balancing, follow domain targets as their DDNS records change, and pass the real client IP onward through PROXY protocol, even when relays chain through other relays. Per-rule concurrency caps, scheduled restarts, and automatic target circuit breaking keep one bad upstream from swallowing the whole route. A built-in shop lets users buy plans and top up balances with redemption codes while quotas drain by measured upload plus download, multiplied per line, so premium routes cost more by design. Traffic charts split the last day, week, or month by line, the node page watches CPU, memory, and connection counts, and Telegram or email alerts fire the moment a relay drops offline. Nodes upgrade from the panel in one click, and the first login forces a password change before anything else opens. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.

Tunnel Panel manages GRE tunnels and port forwarding on Linux servers from a web panel that previews every change before it runs and verifies the result against the kernel. Create GRE, GRETAP, IP6GRE, and IP6GRETAP tunnels and see the exact commands, unit file, and rollback before anything is applied. The far end configures itself from a pairing code, as text or QR, with the sides flipped automatically so the two ends cannot disagree by a typo. Native ICMP probing with hysteresis keeps a single dropped packet from flapping a tunnel between down and back, and when ICMP is filtered the panel knocks over TCP and says so instead of crying wolf. Forward any TCP or UDP port, or a whole range, with round-robin, source-hash, or weighted balancing across destinations, and a backend that stops answering its health knock leaves the ruleset until it recovers. Watch every connection crossing the relay, who connected, which destination took them, and how much has moved, and set traffic limits per tunnel, rule, or destination. When something breaks, diagnostics reach a verdict with evidence and a suggested fix, backed by a streaming manual probe and a path-MTU search that offers to apply its findings. The panel reads your kernel's relay limits, recommends values from the host's memory and cores, and refuses changes that would lock you out of your own server. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

Gately keeps your domain names current, forwards ports, terminates HTTPS, and blocks hostile traffic from one admin console, so a server or home network needs no pile of separate gateway tools. Dynamic DNS updates records at Cloudflare, Alibaba Cloud, Tencent Cloud, DNSPod, Huawei Cloud, Route 53, OVHcloud, Gandi, Namecheap, DuckDNS, and other providers, finding the public address over IPv4 or IPv6 by URL, network interface, or command. Port forwarding relays TCP and UDP with port ranges, failover targets, connection limits, traffic statistics, and PROXY protocol, while SNI routing lets several services share port 443. Certificates are issued and renewed through ACME with DNS-01 wildcards or HTTP-01, then pushed to other hosts over SSH. Web services add per-domain reverse proxies, redirects, and static sites with HTTP/3, WebSocket, load balancing, health checks, rate limiting, caching, and sign-in through OIDC, GitHub, Google, or TOTP-protected shared users. A WAF running the OWASP Core Rule Set and fail2ban-style jails with trap ports and nftables bans guard the edge. Manage Docker containers and Compose projects with one-click upgrades and rollback, open SSH sessions with an SFTP file manager, run ping, traceroute, and speed tests, and receive alerts in Telegram, Discord, Slack, ntfy, or email. An audit log, config history with diff and rollback, encrypted backups, scoped API tokens, and Prometheus metrics round it out. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.

Wag is an authentication gateway for WireGuard that lets each device reach only the routes it should, and asks for a second factor before the sensitive ones open. Admins write access policies for everyone, groups, or single users, marking subnets, hosts, ports, and protocols as MFA-required, always allowed, or denied, and the most specific prefix wins, so one allowed address can sit inside a protected range. Devices join with a registration token, and the public endpoint answers with a finished WireGuard profile. Users then confirm a TOTP code, a WebAuthn security key, an OIDC single sign-on login that maps identity provider groups into Wag groups, or a PAM prompt, and repeated failures lock the account. Session lifetime and idle timeouts decide when they must prove themselves again. The browser portal lists users, devices, rules, registration tokens, and webhooks with real-time notifications, while a command line locks devices, resets MFA, and manages administrators. Webhooks turn JSON from an HR or identity system into new tokens or removed users and devices, and clients can fetch the list of guarded routes from a small API. Remote staff, contractors limited to one host, and homelabs are typical uses. When a server fails, the VPN remains reachable through clustering with witness nodes or an external etcd, and certificates arrive through ACME with HTTP-01 or Cloudflare DNS-01.

Behind one admin panel, DefGuard runs a WireGuard VPN, an identity provider, and multi-factor authentication, so every person and device proves who they are before reaching your private network. Administrators define VPN locations, assign which users and groups may enter each one, and enforce firewall rules that allow or deny traffic per location, with changes applied to gateways in real time. People enroll remotely through a guided self-service flow, register their own laptops and phones, and connect with desktop and mobile clients that show live connection statistics. Sign-in goes well beyond passwords, because the built-in OpenID Connect provider gives internal tools single sign-on, while TOTP codes, WebAuthn and FIDO2 keys, email tokens, and mobile biometrics gate each connection. Directory teams sync accounts from LDAP and Active Directory, or federate sign-in through Google, Microsoft, and custom OpenID providers, instead of maintaining a separate user list. Every authentication, enrollment, and policy change lands in a searchable activity log, and webhooks plus a REST API let surrounding systems react to access events automatically. Gateways keep enforcing access from a local cache when the control plane is unreachable, and several gateways can front the same location for failover.

With over 34,000 GitHub stars and backing from a well-funded engineering team, Tailscale has fundamentally simplified how developers and system administrators think about secure networking. The client daemon establishes WireGuard tunnels directly between devices using sophisticated NAT traversal techniques, achieving direct peer-to-peer connections in the vast majority of network configurations without requiring port forwarding, firewall rules, or VPN concentrators. When direct connections prove impossible due to restrictive network environments, DERP relay servers provide encrypted fallback paths. MagicDNS assigns human-readable hostnames to every device on the network, eliminating the need to remember IP addresses across a tailnet. Subnet routing allows nodes to advertise access to entire local networks, enabling remote access to office resources, home labs, or cloud VPCs through a single gateway node. Exit node functionality routes all internet traffic through a designated device for privacy protection or geographic flexibility. Access control lists define granular policies for which devices and users can communicate with which services, enforced cryptographically at the network layer. The authentication layer integrates with identity providers including Google, Microsoft, GitHub, Apple, and OIDC-compliant systems for single sign-on access. Taildrop enables direct encrypted file transfers between devices without cloud intermediaries. The tailscale CLI provides complete network management from the terminal including status monitoring, route advertisement, and node configuration. Running Tailscale on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console provides a permanent, always-on node in your mesh network.

Give every laptop, server, and cloud VM you own one private address that works from anywhere, and that is exactly the overlay network Nebula builds. Each machine runs a single small binary, presents a certificate signed by your own certificate authority, and joins a peer-to-peer layer-3 mesh where tunnels form on demand between hosts that need to talk. Lighthouse nodes, the piece you park on a VPS, keep track of where every peer can be reached and introduce hosts to each other, so machines find each other without any central VPN concentrator carrying their traffic. UDP hole punching and keepalive packets open direct tunnels through home routers and office NAT, and when two hard NATs refuse to cooperate, a relay host forwards the encrypted traffic until a better path appears. Every host enforces its own firewall, default deny on all overlay traffic, with rules keyed to certificate groups, so laptops in the user-endpoint group can reach a server's web port while other groups cannot. Ordinary hosts need no inbound ports at all, and the same binary runs on Linux, macOS, Windows, phones, and FreeBSD, making the mesh feel identical at home, in a datacenter, or across three clouds. Unsafe routes can even pull an existing office subnet into the overlay, giving legacy hardware that will never run Nebula an address on the private network.

ZTNET provides a polished web dashboard for running your own ZeroTier network controller, covering network creation, member authorization, IP assignment, flow rule editing, and real-time node monitoring entirely from the browser. The organization system supports multi-tenant deployments where teams manage separate network pools with role-based permissions and customizable email notification templates for events like member joins, departures, IP changes, and authorization updates. Each network view displays connected members with their ZeroTier addresses, assigned IPs, last-seen timestamps, physical endpoints, and protocol versions in a clean tabular layout. The admin panel provides platform-wide user management, SMTP configuration for transactional emails, and system-level settings. Built on the T3 stack with Next.js, Prisma ORM, tRPC, TypeScript, and Tailwind CSS with DaisyUI components, the application supports both PostgreSQL and SQLite for persistence and communicates directly with the ZeroTier controller daemon through its native API. Dark and light themes adapt to user preference, and responsive layouts make network management practical from any device. Docker Compose bundles the web application alongside the ZeroTier controller service. Over 100,000 Docker pulls confirm steady community adoption. GPL-3.0 licensed.

Open your laptop in a Lisbon cafe and your files at home answer as if the laptop never left the desk: AnywhereLAN stitches your own machines into one private mesh network with stable names like work-laptop.awl, no port forwarding and nothing exposed to internet scanners. There is no coordination server to trust. Peers announce themselves in the libp2p DHT, identify with ed25519 keys and connect directly over QUIC or TCP with TLS 1.3, hole-punching through NAT and borrowing a community relay only when both ends sit behind hostile firewalls. Send a browser out through the house connection with the built-in SOCKS5 proxy on 127.0.0.1:1066, handy on regional blocks and hostile hotel Wi-Fi. Prefer the full tunnel: the VPN gateway routes every IPv4 byte through a chosen peer, so the whole machine presents the exit node's address to the world. Devices join through invite links or QR codes. Every peer approves its friends and grants exit rights individually, and identity is a keypair you hold, so no account recovery email can betray the network. Manage it from the bundled web UI at admin.awl, script it from the awl CLI, watch it through Prometheus metrics on port 8639, and run it on Windows, macOS, Linux servers and Android phones. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MPL-2.0 licensed.

Most proxies ask the operating system nicely for a socket; paqet skips the conversation, building its own TCP packets byte by byte to tunnel traffic between your machine and your server. The server end listens on a port you choose and speaks only in raw packets it crafts and captures itself through pcap, before the kernel's connection tracking ever sees them. On your machine, the client presents an ordinary SOCKS5 proxy on localhost plus optional port forwards, so browsers and command-line tools connect exactly as they would to any proxy. Between the two ends, KCP with smux multiplexing turns a stream of self-contained packets into fast, reliable, encrypted sessions, with AES or lighter modes selected per deployment. TCP flag cycling varies how packets present themselves on the wire, giving operators control over the traffic pattern the tunnel produces. Built-in utilities generate the shared secret, ping the server with a single test packet, and dump live traffic decoded, so a silent tunnel gets diagnosed in minutes rather than by packet-capture archaeology. One YAML file per side declares the role, network interface, gateway MAC, and keys, and the same binary runs both ends. It suits security research, hostile networks, and anyone whose ordinary proxies keep getting reset.

A self-hosted front door for apps that live on home labs, office LANs, and private clusters, Wiredoor publishes them to the internet without opening a single inbound port on the private side. The Wiredoor CLI on each remote machine dials out to the server over an encrypted WireGuard tunnel. Web apps and APIs are routed by domain and path, WebSocket traffic included, while TCP and UDP services such as SSH or Redis get a public port of their own. Public domains receive Let's Encrypt certificates, internal names fall back to self-signed ones, and Cloudflare or GoDaddy credentials let the server create DNS records itself. Any web route can demand OAuth2 sign-in with an email allow list and a few open paths, and every protocol accepts IP allow lists. Gateway nodes stretch one tunnel across a Docker network, Kubernetes cluster, or private subnet, so a single link serves many backends. Services can be switched off or given an expiry such as 30 minutes, 2 hours, or 1 day. The dashboard shows which nodes are connected and whether their services are enabled, while the CLI creates, enables, and disables services from a terminal. Optional Prometheus and Grafana views chart traffic and tunnel peers, and CrowdSec can block abusive addresses.

Instead of wrestling with raw command-line flags and YAML configuration files for every device on your self-hosted Headscale mesh VPN, Headplane gives you a Tailscale-style web administration console to manage machines, users, DNS records, and access policies from any browser. From the machines overview, network administrators can inspect connected nodes, view Tailnet IPv4 and IPv6 addresses, rename devices, reassign ownership across users, toggle key expiration, and approve advertised subnet routes or exit nodes in a couple of clicks. Built-in Access Control List (ACL) management lets you edit security policies, define user groups, assign node tags, and configure auto-approvers without manually SSHing into your control server. When someone needs immediate shell access to a remote Linux host on the mesh, the integrated WebSSH console opens an interactive terminal session right inside the browser tab over Tailscale SSH. You can also manage MagicDNS settings, configure split DNS nameservers, and add custom DNS records that automatically reload your Headscale instance. Multi-user administration supports OpenID Connect (OIDC) single sign-on with identity providers like Okta, Authentik, Authelia, and Google Workspace, alongside granular role assignments and pre-authentication key generation for unattended server enrollment.

You run one server today and three by next quarter, and each one deserves the same workbench. KPanel is an open-source Linux server management panel with a desktop-style workspace, a classic sidebar mode, multi-host management, and an AI assistant. Open the overview. CPU, memory, disk, load, network, and processes update live, and historical charts answer what happened last night. Sites already on the machine stay where they are. You manage their real Nginx configuration, certificates, reverse proxies, load balancing, and PHP or static stacks in place. Docker gets the same treatment. Containers, images, volumes, logs, and Compose projects are all editable from the panel, and the app market shows real install state. Files and terminals follow you across hosts. Browse one machine, edit on another, run a quick command everywhere, or copy a directory between authorized panels. Lightweight nodes join without Docker. The fleet appears as a list, as cards, or on a globe with latency and service checks, and a public read-only page can show status to anyone who needs it. The assistant reads the state the panel already holds. It answers through fixed tools, asks before acting, and always asks before anything risky.
