I built a multiplayer beat maker because I couldn't find one for my Discord call

I recently launched my very first web app, and I wanted to share the journey with you.

The Problem

A while ago, I was hanging out on a Discord call with a friend. We were bored and wanted to make some music together, just for fun. But we didn't have music production skills and didn't want to install complex software (DAWs) or sign up for expensive services. We just wanted to "click and jam." I realized there was no tool for this, so I built it myself.

The Solution

I built Make a Beat– a minimalist sequencer that runs entirely in the browser. The core feature is real time collaboration: You don't need to create an account. You just generate a room link, send it to a friend, and every beat you place syncs instantly on their screen.

The Validation

I posted it on r/internetisbeautiful last week and it unexpectedly blew up, getting over 35,000 views and a lot of sessions started. Besides that I've published on multiple platforms to get as much feedback from people as possible. I've used all that feedback and kept communicating with users to address pain points and come up with new features.

The Tech Stack

Frontend: React
Backend: Flask, FastAPI
Database: Pocketbase

I need your feedback: Since this is my first real project, I'm looking for brutal honesty:

1. Is the UI intuitive for you?
2. Do you have any feature Ideas?
