What is CommaFeed?

A self-hosted RSS reader that now spends most of its release notes on security.

CommaFeed is a self-hosted Google Reader replacement that has spent the 6.x-to-7.x stretch rebuilding its trust boundaries rather than its feature list. SSRF protection has been tightened in four consecutive releases, feed parsing now strips javascript: URLs before they reach the database, and OPML imports are filtered against import-time abuse. The 7.x line pairs that with client interop: Fever API, ReadKit compatibility, and now the Google Reader API.

What is CoScreen?

CoScreen ships its final build and declares End of Life after a year of quiet.

CoScreen just shipped V8.11.14, explicitly labeled its final software update, alongside an official End of Life announcement. The last real feature release was V8.10 in August 2025 (screen-region sharing plus macOS Tahoe support); the eleven months since produced nothing but this shutdown notice. The multiplayer, multi-window screen-sharing tool for remote teams is being retired rather than iterated.

CommaFeed vs CoScreen: editorial side-by-side

C
CommaFeed
COLLAB
5.0

A self-hosted RSS reader that now spends most of its release notes on security.

◆ Current state

CommaFeed is a self-hosted Google Reader replacement that has spent the 6.x-to-7.x stretch rebuilding its trust boundaries rather than its feature list. SSRF protection has been tightened in four consecutive releases, feed parsing now strips javascript: URLs before they reach the database, and OPML imports are filtered against import-time abuse. The 7.x line pairs that with client interop: Fever API, ReadKit compatibility, and now the Google Reader API.

◆ Where it's heading

The project is positioning itself as a sync backend other people's apps talk to, not just a web reader. Each release adds another protocol or client fix while hardening the assumption that an instance may be publicly exposed with untrusted users on it. The 7.0.0 swap from JEXL to sandboxed CEL and the 7.3.0 flip of blockLocalAddresses to a secure default both trade self-hoster convenience for a safer out-of-the-box posture.

◆ Prediction

Expect continued client-protocol coverage and further SSRF narrowing; the recurring pattern in these entries is that every new fetch path gets a follow-up hardening release.

CoScreen
COLLAB
3.8

CoScreen ships its final build and declares End of Life after a year of quiet.

◆ Current state

CoScreen just shipped V8.11.14, explicitly labeled its final software update, alongside an official End of Life announcement. The last real feature release was V8.10 in August 2025 (screen-region sharing plus macOS Tahoe support); the eleven months since produced nothing but this shutdown notice. The multiplayer, multi-window screen-sharing tool for remote teams is being retired rather than iterated.

◆ Where it's heading

The cadence tells the story: steady usability and performance work through 2024 and into early 2025, a last genuine feature drop in August 2025, then silence until today's EOL. This is a sunset, not a pivot. Users can expect the app to keep running on 8.11.14 but to receive no further fixes or OS-compatibility updates.

◆ Prediction

With EOL declared and a final build shipped, the only moves left are wind-down mechanics: a hard shutdown date, export or migration guidance, and eventual removal from distribution. No further feature work is coming.
