# How to Vibe Code Your Own SoundCloud (and Stop Paying for It)

> Stream and listen to music online for free with SoundCloud

- Site: https://soundcloud.com
- Category: Music & Audio Streaming
- Verdict: **Solid side project** (62/100 vibecodeable)
- Estimated effort: 2-3 weeks part-time

## Verdict

You can build a personal audio-sharing clone with a core upload-and-stream loop, but dealing with raw audio encoding pipelines and synchronized waveforms takes genuine effort.

SoundCloud's core value—uploading tracks, rendering waveforms, playing audio with a persistent player, and leaving timestamped comments—is entirely achievable as a personal-use web app. However, an AI coding agent will stumble when implementing robust audio transcoding pipelines, handling large file upload buffers, and synchronizing canvas-based waveform scraping with playback states. A personal-use clone should scope out massive microservices and licensing engines, focusing strictly on a clean Next.js app backed by PostgreSQL and object storage.

### What you can't replicate

- Massive multi-sided creator and listener network
- Exclusive independent creator catalog and organic community activity
- Enterprise licensing and automated copyright detection infrastructure

## What it does

An online audio distribution platform and music streaming service enabling independent creators to upload, record, and share audio tracks with a community of listeners.

### Core features

- Audio file upload and client-side or server-side waveform rendering
- Continuous audio player with queue management and background playback
- Timestamped track comments bound to exact playback offsets
- User profile pages with track, playlist, and repost management
- Social engagement graph (follow, like, repost, comment)
- Basic stream feed algorithm aggregating followed creators' uploads
- Secure asset storage and streaming delivery pipeline

## The business

### Pricing

- SoundCloud Free: Free — Ad-supported standard streaming access.
- SoundCloud Go+: $11.99/mo — Full catalog access and high-quality offline listening.
- Artist Pro: $8.25/mo — Unlimited uploads and advanced creator analytics.

Founded 2007.
Team size: 700-750.

## The hard parts

- Audio ingestion and encoding pipeline that normalizes arbitrary user uploads into adaptive streaming chunks
- Precise client-side waveform rendering synchronized with real-time audio buffer playback
- Timestamped comment positioning and rendering across fluid UI layouts
- Scalable feed generation and caching for social distribution graphs

## How to vibe code SoundCloud

### Prerequisites

- Node.js (free): Required runtime environment for building and running the full-stack web application.
- GitHub (free): Version control and seamless integration point for deployment infrastructure.

### Recommended AI tools

- Claude Code: Best-in-class terminal coding agent for scaffolding multi-file components, setting up database schemas, and managing full-stack iterations.
- Cursor: Ideal for fine-tuning complex client-side audio player UI components and waveform canvas interactions.

### Stack

- Frontend: Next.js with Tailwind CSS
- Backend: Next.js API Routes / Server Actions
- Database: Neon (Postgres)
- Auth: better-auth
- Payments: none
- Other: UploadThing for fast user file uploads, PostHog for product analytics

### Hosting

- Vercel (Hosting the Next.js frontend and serverless API endpoints with zero-config deployments.): $0-20/mo
- Cloudflare (R2 Object Storage for hosting uploaded audio track files and image assets with zero egress fees.): $0-5/mo

### Build guide

1. **Project Initialization and Database Schema** — Initialize a Next.js project with Tailwind CSS, configure better-auth, and set up the Neon PostgreSQL database schema for users, tracks, comments, and likes.

```
Scrape together a new Next.js project using TypeScript and Tailwind CSS. Configure better-auth with email/password authentication backed by a Neon PostgreSQL database. Define Prisma or Drizzle schema models for Users (id, username, email, avatarUrl, createdAt), Tracks (id, title, description, audioUrl, waveformData, duration, userId, createdAt), Comments (id, body, timestampOffset, trackId, userId, createdAt), and Likes (userId, trackId). Ensure foreign key relations and indexes are correctly specified for efficient querying.
```

2. **Audio Upload and Storage Pipeline** — Implement track upload forms utilizing UploadThing or direct Cloudflare R2 presigned URLs, along with server-side metadata extraction.

```
Create an audio track upload page and API route in Next.js. Integrate UploadThing to handle secure multi-megabyte audio file uploads (MP3, WAV, FLAC). Upon successful upload, store the file URL in Cloudflare R2 object storage, extract track duration using an audio parsing library, and insert a new record into the Tracks table with the associated user ID.
```

3. **Client-Side Waveform Rendering and Audio Player** — Build a global persistent audio player component capable of waveform visualization and playback control across page navigation.

```
Build a responsive persistent audio player bar fixed at the bottom of the layout, powered by a React context state provider. Implement HTML5 audio element hooks supporting play, pause, seek, volume, and track time tracking. Create a waveform canvas component that visualizes audio amplitude data and allows users to click anywhere on the waveform to seek directly to that timestamp offset in the track.
```

4. **Timestamped Track Comments System** — Implement interactive timestamped comments that display along the track's waveform timeline during playback.

```
Develop a comment section component for track detail pages. Allow authenticated users to type a comment and capture the exact current playback time offset of the audio player when submitted. Render comment avatars as floating markers positioned proportionally across the track waveform timeline. Clicking a comment marker should jump the player playback head directly to that specific timestamp.
```

5. **User Profiles and Social Feed Stream** — Construct user profile pages and a home stream feed displaying tracks from followed accounts.

```
Build a user profile page showing avatar, bio, follower count, and a grid of uploaded tracks. Implement a home stream feed query that aggregates tracks uploaded by users whom the current profile user follows, sorted in reverse chronological order. Add follow and unfollow server actions with instant UI optimistic updates.
```

6. **Polish, Layout Styling, and Verification** — Refine the UI to match SoundCloud's signature orange accent theme, responsive layouts, and verify all core loops work cleanly.

```
Refine the UI styling across all pages to mimic SoundCloud's clean, dark-or-light aesthetic featuring vibrant orange accents (#FF3300), rounded container cards, and smooth hover states. Perform end-to-end verification of user registration, track uploading, persistent playback, waveform interaction, and timestamped commenting. Add error boundaries and toast notifications for failed uploads or network requests.
```

### Cost vs paying

**Starting costs (one-time):**

- Custom domain (optional): $12 one-time
- Total: ~$32 one-time (including AI tools)

**Ongoing costs (monthly):**

- Vercel Hobby / Cloudflare R2 storage: $0-5/mo
- Total: ~$0-5/mo

- Paying for the SaaS instead: $11.99/mo (Go+) or $8.25/mo (Artist Pro)
- Build time: 35-50 hours
- AI tool credits: $20 (Claude Pro / Cursor Pro)
- Break-even: Never (built for personal learning and self-hosted utility)
