CommaFeed vs Conceptboard
A side-by-side editorial comparison of CommaFeed and Conceptboard — release velocity, themes, recent moves, and the top alternatives to consider.
CommaFeed vs Conceptboard: 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 Conceptboard?
Conceptboard ships sparingly; Smart sections brings hierarchy and real accessibility to the canvas
Conceptboard ships infrequently, with long gaps between releases and mostly small canvas refinements. The latest and most substantive addition is Smart sections, which adds hierarchical organization to large boards with full keyboard navigation and screen-reader support. Earlier 2026 work was limited to cloud-storage integrations and minor copying and styling tweaks.

CommaFeed
5.0COLLAB

◆ 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.

Conceptboard ships sparingly; Smart sections brings hierarchy and real accessibility to the canvas
◆ Current state
Conceptboard ships infrequently, with long gaps between releases and mostly small canvas refinements. The latest and most substantive addition is Smart sections, which adds hierarchical organization to large boards with full keyboard navigation and screen-reader support. Earlier 2026 work was limited to cloud-storage integrations and minor copying and styling tweaks.
◆ Where it's heading
The pace is slow and the changes incremental, but accessibility is an emerging emphasis, with Smart sections leading on keyboard navigation and screen-reader descriptions for canvas content. Cloud integrations and visual customization round out the recent work. The direction reads as steady refinement of the existing whiteboard rather than expansion.
◆ Prediction
Expect continued low-frequency releases focused on canvas usability and accessibility, possibly with more board-organization and integration features. The sparse cadence makes a confident near-term call difficult.
