How to Start Live Coding on YouTube: Tips, Tools, and Lessons Learned

I began live‑coding on YouTube in July of last year, streaming my work on open‑source JavaScript hardware libraries and naming the channel “JavaScript Hardware Development”.

Inspired by early streamers such as Handmade Hero and Vlambeer, and motivated by a friend who streamed weekly open‑source work, I decided to share my own experience.

After setting up a YouTube room with OBS, I streamed my first session while working on the Avrgirl‑Arduino library. The first broadcast was nerve‑wracking, but encouragement from a small audience helped me continue, eventually growing to over a thousand followers.

Live coding feels like large‑scale pair programming; viewers often point out simple mistakes, such as forgetting to insert a chip on a circuit board.

When I’m not streaming, I only go live for PR reviews or major feature demos because my schedule is tight.

Software

There are many streaming programs, but I use Open Broadcaster Software (OBS) because it is free, cross‑platform, and easy to learn. OBS lets you create scenes composed of input sources such as camera, microphone, desktop, browser, text, and images.

My main scene shows my desktop with iTerm, Vim, and a browser for documentation. A black rectangle at the bottom displays my webcam so viewers can see me working.

I also add a custom banner (created in GIMP) that shows follower count, temperature, and humidity, imported as a browser source.

For alerts (new followers or donations) I use Stream Labs, which injects a banner at the top of the stream.

When entering sensitive tokens or API keys I switch to a “privacy” scene that hides my desktop behind a fun webpage.

Hardware

I started with cheap gear and later upgraded to a Logitech C920 webcam and a Blue Yeti microphone, which dramatically improved stream quality.

I use a single 27‑inch monitor to keep everything on one screen, avoiding the distraction of a second monitor.

Small Tips

Prepare a detailed room description that includes chat rules, hardware specs, and personal touches. Look at popular channels for inspiration.

Chat

Engage with viewers using macro commands (e.g., Nightbot) to answer frequent questions quickly. Acknowledge comments and thank contributors; regular interaction keeps the audience invested.

Preparation Time

Automate your window layout with iTerm profiles so you can switch between a “live” and a “non‑live” arrangement with a single command.

Make sure fonts in your terminal and editor are large enough for viewers to read.

Maintain Regularity

Stream at a consistent weekly time so viewers know when to tune in. Consistency helps build a loyal audience.

Tricky Issues

Feeling self‑conscious at the start is normal; remember that viewers are supportive and often help improve your code. Live coding forces you to write readable, functional code first, then optimise later.

Conclusion

If you want to live‑code on YouTube, give it a try! I hope this guide helps you get started.
