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 Notion?

Notion is building the place where other companies' agents come to work

The 3.5 and 3.6 releases turned Notion into a developer platform: Workers run custom code on Notion's infrastructure, a CLI and Markdown API exist for coding agents, and External Agents bring Claude and Cursor onto a shared board where a team can assign and watch them. Custom Agents have accumulated the surrounding machinery in the weeks since — five more MCP connections, calendar tools, Outlook mail, Microsoft file read and write, audit-log coverage, and a people directory. The most recent entries are smaller and mostly about wiring: sharing context from the Share menu, sharing Workers across a team, and surfacing Worker usage in the credits dashboard before the free beta ends.

CommaFeed vs Notion: editorial side-by-side

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.

Notion is building the place where other companies' agents come to work

◆ Current state

The 3.5 and 3.6 releases turned Notion into a developer platform: Workers run custom code on Notion's infrastructure, a CLI and Markdown API exist for coding agents, and External Agents bring Claude and Cursor onto a shared board where a team can assign and watch them. Custom Agents have accumulated the surrounding machinery in the weeks since — five more MCP connections, calendar tools, Outlook mail, Microsoft file read and write, audit-log coverage, and a people directory. The most recent entries are smaller and mostly about wiring: sharing context from the Share menu, sharing Workers across a team, and surfacing Worker usage in the credits dashboard before the free beta ends.

◆ Where it's heading

Notion is positioning itself as the orchestration layer rather than another agent vendor, which is a different bet than most of its competitors are making. The supporting work is consistent with that: Workers to run the code, a credits dashboard to price it, an audit log to govern it, and sharing so one person's Worker becomes a team asset. The recent shift from platform launches to permissions, sharing and billing surfaces is what a product does after the capability lands and adoption becomes the constraint.

◆ Prediction

Workers move onto paid credits on August 11, so the near-term work should keep clustering around usage visibility and cost controls. The trigger surface is the other thread to watch — meeting notes became an agent trigger this window, and the same pattern applied to other Notion events is the obvious next step.
