Audio and podcasting decision
Transistor
A single developer can build a narrow self-hosted podcast host (upload, RSS, player, basic analytics) over several weeks, but reproducing Transistor's full commercial polish, dynamic ads, transcription add-ons, and production-scale reliability is costly—so keep paying for advanced features.
Visit website↗Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.
What a replacement has to do
- Upload audio files, publish episodes (RSS), serve audio via CDN, provide a simple episode website and embed player, track downloads/analytics.
What it still won’t have
- Commercial-grade dynamic ad insertion tooling and management
- Built-in AI transcription add-on (managed)
- Polished multi-show website builder and templates
- Live customer support and managed uptime/scale guarantees
- Private podcast subscriber management UI and paywall features
What remains hard
- Product polish and ongoing maintenance
First-year cost
Keep paying
Paying is—cheaper in year one.
On cash alone, building overtakes the subscription at 1 seat.

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal podcast hosting service using Node.js (Express), Postgres, and AWS S3 + CloudFront. In scope: account and show creation, upload MP3/MP4 episodes (max 1GB), store metadata in Postgres, generate per-show RSS feeds, a web UI to create/publish episodes, an embeddable JS audio/video player, and basic analytics (download counts aggregated hourly). Out of scope: dynamic ad insertion, multi-tenant billing, transcription, advanced templates, and enterprise-scale autoscaling. Provide error handling for uploads, RSS generation, and CDN invalidation; include unit tests for RSS generation and upload flow and integration tests for publish->RSS updates.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
