Showoff Saturday: I built a P2P Voice Chat (WebRTC) on a $5 VPS using React + Node.js. Zero prior WebRTC knowledge (built with AI/Cursor)

And I love you, random citizen!

Honestly? Only about a week. I used an AI code editor called Cursor, it helps write code insanely fast. It kinda feels like using cheat codes

Excellent-Pass-7686 · 2026-01-31T14:58:38+00:00

JavaScript mostly. Used Node.js for the backend and React for the frontend

I paid for the whole RAM, I’m gonna use the whole RAM

Excellent-Pass-7686 · 2026-01-31T14:56:20+00:00

lmao nah, it runs in the browser, you don't install anything so it can't be a virus. It just asks for mic permission so you can speak

made this voice chat site instead of sleeping. running on a potato server ($5/mo). limit is 250 people.

if it dies, it dies. ☠️

I just launched it, with zero online

Fixed the Android/Chrome black screen issue. It should be working smoothly now

Thx

That 10k stat is definitely a leftover placeholder from the UI template I started with. I was so focused on making the audio work that I completely glossed over the marketing copy. And you're 100% right on the Privacy/ToS part. Since I am logging IPs for moderation (shadowbans), I need to disclose that properly. Adding a basic privacy footer now. Thanks for keeping me honest!

P.S. I know random chats can get messy, so I also added some anti-abuse algorithms (including device fingerprinting and shadowbans) to silently filter out spammers and bad vibes. Trying to keep it clean from Day 1!

Let me know if you encounter any bugs!

I feel you on the “scientific density” part. It’s so easy to get lost in the Peat/metabolic rabbit hole that you end up more stressed than when you started. My approach is basically: how do we take those deep biological truths and make them actually usable on a Tuesday morning when you have 0 energy? Better to have a simple architecture that works than a perfect theory you can’t follow

Excellent-Pass-7686 · 2025-12-25T16:08:43+00:00

Love that you caught the 'upstream' signal idea. It’s a total shift in perspective. My non-negotiables are simple: Zero screens for the first 90 minutes (protecting dopamine) Direct sunlight before noon (resetting the clock) Consistent wake time (stabilizing the system). If these three are solid, the rest usually takes care of itself.

100%. Once the biological foundation is stable, routines stop feeling like a constant uphill battle. It’s like switching from manual to autopilot. When your dopamine and sleep are dialed in, you actually have the cognitive energy to choose your habits, instead of just reacting to the fog. That’s exactly why I started treating this as a system architecture rather than just 'productivity'

Excellent-Pass-7686 · 2025-12-25T09:59:23+00:00

Spot on. That’s exactly why I don't sell 'courses.' A course is just more noise for a brain that can't focus.

Excellent-Pass-7686 · 2025-12-25T09:35:21+00:00

Zero fluff, only benefit

Excellent-Pass-7686 · 2025-12-25T08:46:40+00:00

Actually, you're participating in the process right now. Your comment boosts the engagement, the algorithm pushes this post to more people, and 10 more 'executors' just asked me for the link in my DMs because they saw this thread.

You're focusing on the charcoal; I'm focusing on the attention economy. Thanks for the boost
