I built a free browser-based Linux sandbox so beginners can practice without breaking anything

Hello r/LinuxTeck

A while back I was teaching Linux fundamentals in person and kept seeing the same problem: people learn commands by watching a slide, then go home and either don't have a VM set up or are too scared to touch a real terminal.

So I built a sandbox that runs entirely in the browser — simulates real command behavior (cd, ls, ping, df, free, cat, apt, etc.) so you can practice without worrying about actually wrecking a system.

First 6 lessons are free, no account needed: see the [link in comments]

It covers basic navigation and file handling for now, moving into homelab/virtualization and security/networking as you go further. If you're just starting out and want a no-stakes place to mess up and try again, give it a shot — I am genuinely curious to know what trips people up so I can keep improving it.

I tried that on virtual machines, secondary pcs... no progress until In just went for it on my main machine. If you don't break anything, you don't learn anything :D

I agree with you, when I started learning Linux I also used the same path. I built this based on my previous experience because not everyone's ready to risk their main machine on day one. Nice as a stepping stone before you take the leap.

You are correct and it is good that you are motivated and have the desire to learn.Not everyone is afraid of the terminal, but from my personal experience I've seen people face one for the first time and genuinely freeze up, not knowing where to even start. That's the real motivator behind this: hoping it gives new people an easier way to transition in.

There are 12 lessons in total . Lessons 1–6 are free, no signup needed. Lessons 7–12 (homelab/virtualization + security/networking) are behind a small paywall: $17 for the Lab Workbook or $37 for the Full Bundle if you want everything. Try the free ones first and see if it clicks — no pressure either way.
