Should you build your own Transistor?
Publish a private or public RSS feed from user-owned audio storage
A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Transistor, publish a private or public RSS feed from user-owned audio storage. The hard boundary is reliable hosting, multiple shows, analytics, team access, and directory support, plus audio infrastructure, distribution, and production polish.
ENOriginal research content in English. Original prompt preserved in English.
Build a closest honest personal substitute for Transistor in an empty repository.
Use Python 3.12, FastAPI, ffmpeg, SQLite, and an HTMX interface; do not offer alternative stacks.

Make the first run work locally with one documented command.
Store all user data locally by default and make export straightforward.
Put secrets in .env, ship .env.example, and never commit credentials.
Create an upload queue and preserve originals in a read-only media folder.
Generate waveforms and non-destructive edit markers instead of rewriting source files.
Implement silence trimming, loudness normalization to -16 LUFS, fades, and noise-gate presets.

What would building your own look like?
Import spoken-word audio, perform practical cleanup, assemble an episode with show notes, and publish a private or public RSS feed from user-owned audio storage.
What you will need
- ffmpeg
- local audio files
- optional transcription API key
- sufficient disk space
People still pay for Transistor because creators pay to remove fragile audio plumbing and publishing chores from a release schedule. The recurring cost buys codec support, loudness standards, transcription, storage, feeds, analytics, and deliverability to directories, not just the visible interface.
