Deploy and Host Kali Linux Web Terminal on Railway

A Kali Linux terminal that runs in the cloud and opens in any browser. Sign in with a password and get a full bash shell with sudo, a persistent home folder and a tmux session that keeps running when you close the tab. No SSH client or keys needed.

About Hosting Kali Linux Web Terminal

The template builds kali/Dockerfile from the open source repo github.com/nerminsabanovic31/railway-web-terminals on top of the official kalilinux/kali-rolling image. ttyd serves a full shell over Railway's HTTPS domain, protected by HTTP basic auth with USERNAME and a generated PASSWORD that you copy from the service Variables. The shell runs inside tmux, so closing the tab never kills your work, and the home folder lives on a volume at /data, so files survive restarts and redeploys.

Common Use Cases

Learning Linux and security tooling on a box you can reach from any browser
CTF practice and labs on your own targets without a local virtual machine
A disposable Kali shell you can redeploy in minutes

Dependencies for Kali Linux Web Terminal Hosting

No other services: one container plus a volume
Any modern browser; works on phones and tablets too

Implementation Details

Open the Railway domain, sign in with USERNAME and PASSWORD, and you are in a bash shell as a user with passwordless sudo. Preinstalled: git, curl, wget, vim, nano, htop, tmux, Python 3 with pip, nmap, whois and netcat. Install anything else with:

sudo apt update && sudo apt install -y kali-tools-web

Close the tab at any time; reopen the domain to land back in the same tmux session. 512 MB of memory is plenty for most work.

Only test systems you own or have written permission to test. Railway's Fair Use Policy applies.
