A side-by-side editorial comparison of Fonoster and RSS.com — release velocity, themes, recent moves, and the top alternatives to consider.
Fonoster parks its Deepgram diarization work after two 0.22.x stability patches.
Fonoster's last releases were September patches to the 0.22.x audio SDK: v0.22.13 made playStream resolve only after playback completes, and v0.22.14 caught unhandled rejections on hangup that could crash the Node.js process. The newest item is not a release but an archive tag parking a Deepgram streaming diarization speaker filter written against the old apiserver.
RSS.com opened a public API, then its changelog went quiet
RSS.com is a podcast hosting platform that spent late 2025 shipping ecosystem features — a public API, Podcasting 2.0 Location Tags, and a year of analytics lookback. Its changelog has not updated since December 2025, so more recent direction is unclear.

The project is in maintenance mode on 0.22.x, with no new feature surface since September. Archiving the diarization work suggests speaker-aware transcription isn't shipping on the old apiserver path.
It's unclear when a 0.23.0 feature release lands; the entries show a month-long gap and parked rather than shipped speech features.
RSS.com is a podcast hosting platform that spent late 2025 shipping ecosystem features — a public API, Podcasting 2.0 Location Tags, and a year of analytics lookback. Its changelog has not updated since December 2025, so more recent direction is unclear.
The late-2025 arc pointed toward opening the platform up: an API for third-party automation and standards-based metadata. Whether that momentum continued isn't visible, as the feed has been silent for months.
Insufficient recent data to predict confidently; the last visible direction was building API-driven integrations, but the months-long changelog gap makes any near-term call speculative.
