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 Outline?

Outline gave AI assistants write access to the wiki, then spent months on the human side.

The April MCP expansion is the structural change in this window: assistants can patch documents, move and delete documents and collections, work with attachments, and create and resolve inline comments. Everything since has been human-facing and smaller — request-access flows for documents members cannot open, email subscriptions to publicly shared documents with change summaries, task list and checkbox handling in the editor, and profile cards on avatar hover.

CommaFeed vs Outline: 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.

Outline

2.5

Outline gave AI assistants write access to the wiki, then spent months on the human side.

◆ Current state

The April MCP expansion is the structural change in this window: assistants can patch documents, move and delete documents and collections, work with attachments, and create and resolve inline comments. Everything since has been human-facing and smaller — request-access flows for documents members cannot open, email subscriptions to publicly shared documents with change summaries, task list and checkbox handling in the editor, and profile cards on avatar hover.

◆ Where it's heading

Two audiences are being served in sequence. The MCP work moved assistants from reading the knowledge base to editing it, including the collection structure itself. The releases after it close ordinary gaps in how people find, follow and get into documents — which is what a wiki needs before more of its edits arrive from automation. Release cadence is roughly monthly with entries that describe outcomes rather than changelogs.

◆ Prediction

Expect the human-facing polish to continue at its current pace, with any next structural move likely extending the MCP surface further into permissions and collection management, since that is where the existing tools stop.
