Fonoster vs RSS.com: at a glance
What is Fonoster?
Fonoster now cleans up deleted workspaces and stops exposing stored secrets.
Fonoster ships minor versions almost daily. v0.51 to v0.53 added Anthropic, Google and Groq models, TTS voice choice and one-switch call recording. From November 10, v0.54 to v0.56 added branded emails, legal pages, webhook event lookups and API key rotation, and v0.57 returns secret values only to API keys, cancels a deleted user's plan, and ends a deleted workspace's calls and resources.
What is RSS.com?
RSS.com is adding reasons for podcasters to stay, from listener voicemail to a free academy.
RSS.com ships about one bundled release a month. The last two added listener voicemail (60-second browser recordings linked from every episode's notes) and a free Learning Center with 22 courses built from its own blog and video library. Last year's public API remains the biggest change to what the platform can do.

Fonoster
7.5COMMS
Fonoster now cleans up deleted workspaces and stops exposing stored secrets.
◆ Current state
Fonoster ships minor versions almost daily. v0.51 to v0.53 added Anthropic, Google and Groq models, TTS voice choice and one-switch call recording. From November 10, v0.54 to v0.56 added branded emails, legal pages, webhook event lookups and API key rotation, and v0.57 returns secret values only to API keys, cancels a deleted user's plan, and ends a deleted workspace's calls and resources.
◆ Where it's heading
After a quick run of voice-AI options, Fonoster has turned to what a hosted service needs before paying customers rely on it: legal pages, billing correctness, webhook debugging and account deletion that actually removes data. The cadence stays daily and the changes stay incremental.
◆ Prediction
More account and billing lifecycle work is likely next, since v0.57 adds a billing test case and deletion rules in the same release.
RSS.com
2.5COMMS
RSS.com is adding reasons for podcasters to stay, from listener voicemail to a free academy.
◆ Current state
RSS.com ships about one bundled release a month. The last two added listener voicemail (60-second browser recordings linked from every episode's notes) and a free Learning Center with 22 courses built from its own blog and video library. Last year's public API remains the biggest change to what the platform can do.
◆ Where it's heading
With hosting itself a commodity, RSS.com is competing on what surrounds it: audience interaction, education for new podcasters, and open standards such as Podcasting 2.0 tags. The API gives technical users a way to automate, while the academy and voicemail aim at beginners.
◆ Prediction
The entries show steady monthly releases but no clear next feature, so the specific next move is unclear.
