Ever typed rm -rf / into your brain before your terminal? Yeah… same.
But what if there was a zero-risk place to try commands without breaking your system or nuking your $HOME folder?
🧪 Meet: TerminalSandbox
This is a web-based terminal sandbox I built for fun (and learning).
It's backed by a FastAPI-powered backend that safely runs Debian-based shell commands in isolated environments — straight from your browser.
Use it to:
✅ Learn and test Linux CLI basics
✅ Practice without needing a VM or Docker
✅ Demo commands live to others
✅ Build your confidence in Bash, one ls at a time
✅ Feel like a hacker with absolutely no danger 🚨
🔒 But is it safe?
Yes. I’ve sandboxed the environment:
- Every user gets their own temporary isolated directory
- Dangerous patterns like
rm -rf,shutdown,reboot, etc. are blocked - Only safe, whitelisted commands are allowed (with descriptions)
- No persistent file system access
- Sessions expire and self-clean
Think of it like a toddler-safe terminal: you can poke around, break things (sort of), and nothing really explodes.
⚙️ Tech Stack
Here’s the nerdy part:
- FastAPI backend (Python 3.11)
- Async command execution with stdout/stderr capture
-
uvicorn+slowapifor rate limiting - Hosted sessions with UUIDs and safety checks
- Frontend is served via Cloudflare Pages
- Currently supports Debian-based commands only — but Arch might sneak in soon 👀

📢 Why I built this
I love Linux. I love web stuff. And I really love giving folks a way to learn without fear.
This started as a sandbox experiment — now it’s a tool I genuinely use to teach, debug, and play.
If you’ve ever wanted to:
- Share shell snippets without spinning up an instance
- Help a friend learn terminal basics
- Or just flex your
htopin peace
Then TerminalSandbox might be your jam. 🖥️
🙌 Try it, Fork it, Break it (Safely)
Give it a spin. Share feedback. Fork it and build your own flavor.
If this project made you smile, star the repo or drop a comment.
Let’s make the terminal a little more welcoming — one echo at a time.
