What is Fonoster?

Fonoster ships four releases in a day to make linking a Twilio number a single step.

Fonoster went from v0.35 to v0.38.1 on October 28. The thread is Twilio: trunk provisioning for a number link is now idempotent, a Twilio number can be linked to an app or SIP agent in one API call, linking moved server-side with an API key or Auth Token (a breaking change), and the Numbers page can do it from the UI. v0.35 also lets Routr be configured through routr-one.yaml.

What is RSS.com?

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.

Fonoster vs RSS.com: editorial side-by-side

F6.3

Fonoster ships four releases in a day to make linking a Twilio number a single step.

◆ Current state

Fonoster went from v0.35 to v0.38.1 on October 28. The thread is Twilio: trunk provisioning for a number link is now idempotent, a Twilio number can be linked to an app or SIP agent in one API call, linking moved server-side with an API key or Auth Token (a breaking change), and the Numbers page can do it from the UI. v0.35 also lets Routr be configured through routr-one.yaml.

◆ Where it's heading

After rebuilding its SIP and media edge and defaulting to HTTPS in the 0.31 to 0.33 run, Fonoster is now working on onboarding, using Twilio as the way to bring an existing number. The release rate stays very high and breaking changes still land in minor versions.

◆ Prediction

Expect the same number-linking flow for other carriers, or more Numbers page work; the entries only cover Twilio so far.

RSS.com opened a public API, then its changelog went quiet

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.
