The verdict: can you vibe code Libsyn?
Build a focused subset for personal podcast hosting and RSS syndication, but keep paying if you need programmatic ad-network payouts and multi-platform advertising sales.
The core loop of uploading an MP3, generating a spec-compliant RSS XML file, serving media files via cloud storage, and viewing basic download counts is a solid side project that can be built cleanly. However, replicating an IAB-certified analytics pipeline that accurately filters thousands of rogue data-center scraping bots and implementing dynamic ad audio-splicing is a major engineering hurdle that will consume significant debugging time.
Estimated effort: 2-3 weeks part-time

- Over $112M creator ad-payout network and direct brand sponsorship inventory
- Deep institutional distribution agreements and direct partnership queues with Apple, Spotify, and YouTube
- Two decades of continuous operational reliability and migration trust for 250,000+ active shows

Build guide
01Project Scaffolding and Database Schema
Initialize the Next.js project with Tailwind CSS, configure Turso for SQLite storage, and implement better-auth for user accounts.
Scaffold a new Next.js 16 application using TypeScript and Tailwind CSS v4. Set up Turso for database connectivity via libSQL and configure better-auth with email/password authentication. Create database tables for users, shows (podcasts), episodes (title, description, audio_url, duration, file_size, publish_date), and analytics_events (episode_id, user_agent, ip_hash, timestamp). Ensure clean separation of server actions and database client utilities.02Media Uploads and Cloudflare R2 Integration
Build an authenticated podcast dashboard allowing creators to upload heavy audio and video files directly to S3-compatible cloud storage.
Build a podcast management dashboard in Next.js featuring a multi-step episode creation wizard. Implement file upload functionality utilizing Cloudflare R2 (or UploadThing as an S3-compatible intermediary) to handle large MP3 and MP4 binary payloads securely. Extract audio duration and file metadata upon upload completion, saving the file asset URL and size back to the Turso database under the active show's library.03Dynamic RSS XML Feed Generator
Create an automated RSS 2.0 feed route adhering to Apple Podcasts and Spotify iTunes namespace specifications for each podcast show.
Create a dynamic API route in Next.js that generates a spec-compliant RSS 2.0 XML feed for any given show slug (e.g., /shows/[slug]/rss.xml). Include required iTunes namespace tags (<itunes:author>, <itunes:owner>, <itunes:image>, <itunes:category>, <itunes:explicit>), enclosure tags with exact file lengths and mime types, and proper pubDate formatting. Test the XML structure against standard podcast validators to ensure compatibility with Apple Podcasts and Spotify.04Custom Embeddable Web Player Widget
Design and code a brand-customizable HTML5 audio/video player widget that can be embedded into external websites.
Develop a responsive, brand-customizable embeddable podcast player widget as a standalone React component and embed route. Allow show owners to customize primary accent colors, play button styles, and artwork borders via dashboard settings. The player must support standard HTML5 audio/video playback controls, progress bar scrubbing, skip forward/backward 15 seconds, playback speed adjustment (1x, 1.25x, 1.5x), and emit play/listen event pings back to the analytics endpoint.05Analytics Tracking and Bot Filtering Pipeline
Implement a lightweight download tracking endpoint that parses User-Agents and logs verified episode plays.
Build a high-performance download tracking endpoint that intercepts media file requests routed through the platform. Implement User-Agent parsing logic to filter out known scrapers, curl requests, and data-center crawler bots in accordance with basic IAB filtering guidelines. Hash incoming IP addresses for privacy compliance, record unique daily downloads and geographic distributions in Turso, and construct an analytics dashboard view with charts showing download trends over time.06Team Access Control and Polish
Add multi-user management features allowing up to five collaborators per show and finalize dashboard navigation UI.
Implement multi-user show access control allowing primary show owners to invite up to five team members with distinct roles (admin, editor, contributor) via email invitation tokens managed through better-auth. Polish the entire Next.js dashboard UI with clean navigation tabs for Episodes, Analytics, Embed Player, and Settings, ensuring responsive layouts and graceful error handling on all forms.
