doom-coding

A DIY approach to coding on-the-go!

As an aspiring builder, I sought out a way to keep coding while not at home. Thanks to some Claude-assisted research and troubleshooting, I can now code via the terminal on my phone anywhere at anytime via "Doom Coding" (think Doom Scrolling but more productive).

After this 5-minute setup guide, you’ll be able to "doom code" anywhere you have Internet connection.

Code in the air!

Code on a run!

Even code at the club!

I’ve been amazed by how much I can get done while being so far away from home. In Taiwan, I could access my computer in Philadelphia and coded a prototype in my downtime.

Shameless plug: check out www.friendlyr.ai to help shape the future of connection!

Make sure to "Watch" this repo for future updates to this doom coding guide. As I tryout the latest mobile coding tools (e.g. Claude Code on the Web), I’ll update this repository with comparisons.

Happy doom coding my friends!

What You’ll Need

1. A Computer running 24/7 with Internet Connection
2. A Smartphone
3. A Claude Pro subscription

Overview

Use Tailscale, Termius, Claude Code, and a computer running 24/7 to continue building anywhere you have Internet connection.

Getting Started

1. Set Up Your Computer

2. Set Up Your Phone

Install Tailscale → Sign in with the same account https://apps.apple.com/us/app/tailscale/id1470499037

Install Termius (A Mobile Terminal Tool) https://apps.apple.com/us/app/termius-modern-ssh-client/id549039908

Note the MagicDNS address of your computer (e.g. my-computer.tailnet-name.ts.net)

Create a new host in Termius:

• Label: What you want your connection to be called
• Hostname: The MagicDNS address (my-computer.tailnet-name.ts.net)
• Port: 22
• Username/Password: Your login for your computer

3. Connect and Code

Troubleshooting

• If you’re not able to establish a connection from your phone via Termius to your computer:

1. Reset your Tailscale VPN

• Check your phone settings to make sure you are connected to the Tailscale VPN.
• Check the Tailscale app to make sure the Tailscale VPN is on. If your phone and doom coding computer do not have a green circle next to their labels, there is an issue with your Tailscale/Internet connection.

2. Make sure your computer is ON and UNLOCKED

When disconnecting/reconnecting power, make sure you unlock the computer. I’ve ran into this issue one too many times.

Best Practices

Track your progress:

End sessions by asking Claude to update CLAUDE.md with where you left off.

Preview websites:

Go to your desired directory and start an HTTP server python -m http.server 3005 then visit http://your-machine.tailnet-name.ts.net:3005/your-html-file.html in a browser on your phone.

Wherever you would use localhost:PORT to view an app on your computer, replace localhost with the computer’s MagicDNS from the Tailscale app (e.g. your-computer.tailnet-name.ts.net)

View databases:

Use the PostgreSQL app to view databases for your projects https://apps.apple.com/us/app/postgresql-client/id1233662353

Bookmark useful sites:

On your computer, bookmark the sites you refer to during development (e.g. Google OAuth, GitHub) to make it easier to reference from your phone. I use the Chrome app to seamlessly access the sites I need.

Happy Doom Coding!

Please contibute your best practices! I am looking forward to seeing all the places you will code!
