fxTunnel's paid plan starts at $2.50 a month; CloudPub PRO is 399 RUB (source: cloudpub.ru/plans, September 2026). The free tiers differ more than the prices do: CloudPub publishes HTTP and HTTPS only and caps traffic at 250 GB a month, while fxTunnel gives you HTTP and TCP with no traffic cap on any plan. TCP, UDP and SSH require PRO at CloudPub; fxTunnel has TCP on the free plan and UDP from Base.
CloudPub lists eleven protocols as separate features: RDP, VNC, WebDAV, RTSP, 1C databases. Worth knowing that nearly all of those are ordinary TCP and HTTP services. Through fxTunnel they take the same single command: a remote desktop is "fxtun tcp 3389", an RTSP camera is "fxtun tcp 554", WebDAV file access is a plain HTTP tunnel. We have no per-protocol modes because the transport underneath is the same one.
The difference is what sits on top, and it is real: CloudPub builds a bastion over RDP and VNC with session recording and an audit log. If you need not just to reach a desktop but to keep records of who connected, that is their ground and we do not pretend otherwise. If you need the access itself, a TCP tunnel does it, and TCP is on our free plan.
CloudPub's free plan caps traffic at 250 GB a month and carries HTTP/HTTPS only, though it does hand you a permanent subdomain straight away. fxTunnel's free plan is one tunnel on any free subdomain with no limit on traffic, requests or session length — the name is yours while the tunnel runs, and reserving it permanently starts on Base.
Both services are Russian, both take Russian cards and work without a VPN. Clients cover Windows, Linux and macOS; CloudPub also lists Android. fxTunnel can be self-hosted — the whole stack is open, the server included.
fxTunnel ships a desktop application for Windows, Linux and macOS: tunnels start with a click, and the built-in inspector shows every HTTP request with headers and body and replays it in one click. CloudPub is driven from the CLI and a web dashboard, with traffic recording and analysis on PRO.
fxTunnel's whole stack is open: the Go server, the CLI, the desktop app and the web interface — you can run your own server and depend on nobody. CloudPub's client is open; the server is a product, and installing it on your own infrastructure is an Enterprise arrangement.
fxTunnel is cheaper, caps bandwidth on no plan, gives you TCP on the free tier and is open end to end — including the server, which you can run yourself. Everything usually listed as a protocol menu — RDP, VNC, databases, cameras — goes through the same tunnels.
CloudPub earns the choice in one case: when what you need is not access but control over access — a bastion with session recording, an audit log, a compliance story. We do not have that and will not soon.
