CommaFeed vs Linear: at a glance
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 Linear?
Linear stopped being where work is described and became where it gets started.
Linear's recent output is dominated by one thread: an in-product agent. Linear Agent shipped, gained MCP so it can reach tools outside the workspace, and picked up intake from Intercom, Zendesk and Gong plus a deeplink handoff into external coding tools. Around it sits steady tracker work — team owners and permissions, multi-level sub-teams, time-in-status, advanced AND/OR filters, Releases, web forms for Asks, and a broad UI refresh.

CommaFeed

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.
Linear
0.0COLLABPM
Linear stopped being where work is described and became where it gets started.
◆ Current state
Linear's recent output is dominated by one thread: an in-product agent. Linear Agent shipped, gained MCP so it can reach tools outside the workspace, and picked up intake from Intercom, Zendesk and Gong plus a deeplink handoff into external coding tools. Around it sits steady tracker work — team owners and permissions, multi-level sub-teams, time-in-status, advanced AND/OR filters, Releases, web forms for Asks, and a broad UI refresh.
◆ Where it's heading
The centre of gravity is moving from recording work to attempting it. Each release widens the agent's reach in a different direction: MCP for tools, support integrations for intake, deeplinks for handoff to coding agents. The conventional tracker features increasingly read as the substrate the agent operates on rather than the product itself.
◆ Prediction
Expect the next moves to deepen agent context and control rather than add tracker surface — more MCP-reachable actions, and permissions or review steps governing what the agent may do on its own.
