CommaFeed vs Tana: at a glance
What is CommaFeed?
CommaFeed is patching its way through the attack surface a self-hosted reader inherits
CommaFeed's 7.x line has become a sustained security pass. The newest patch closes Host header injection on the password recovery endpoint and adds a commafeed.password-recovery-public-base-url setting so the email base URL is configured rather than taken from the request. Behind it: local address blocking made secure by default alongside Google Reader API support in 7.3.0, javascript: URLs filtered at parse time in 7.2.1, and SSRF limits on the image proxy in 7.2.0.
What is Tana?
The knowledge graph quietly turned itself into a meetings product.
Every release in this window touches meetings. Tana added a pre-meeting hub card, an always-on-top join nudge for internal calls, one-click conversion of a scheduled call into an external capture, a Present palette in the call toolbar, a voice picker for meeting agents, and action cards on Today for starting, scheduling or capturing a meeting. The AI work runs alongside it — chat that costs fewer tokens for the same quality, and an assistant that can pin things or hand you a shareable link to a document it referenced.

◆ Current state
CommaFeed's 7.x line has become a sustained security pass. The newest patch closes Host header injection on the password recovery endpoint and adds a commafeed.password-recovery-public-base-url setting so the email base URL is configured rather than taken from the request. Behind it: local address blocking made secure by default alongside Google Reader API support in 7.3.0, javascript: URLs filtered at parse time in 7.2.1, and SSRF limits on the image proxy in 7.2.0.
◆ Where it's heading
Every release in this stretch closes a path where content or a request from outside the instance was trusted too far - feed URLs reaching internal addresses, proxied images, javascript: links, and now a header shaping an outbound email. That is the checklist of a project being run as a multi-user hosted service rather than a single-user tool, and it follows directly from the 7.0.0 decision to sandbox filter expressions. Feature work continues in parallel but is clearly the smaller half.
◆ Prediction
The remaining untrusted-input surfaces - OPML import and the feed fetcher's redirect handling - are the likely next targets. The pattern of shipping each fix as its own patch release should continue rather than batching them.

The knowledge graph quietly turned itself into a meetings product.
◆ Current state
Every release in this window touches meetings. Tana added a pre-meeting hub card, an always-on-top join nudge for internal calls, one-click conversion of a scheduled call into an external capture, a Present palette in the call toolbar, a voice picker for meeting agents, and action cards on Today for starting, scheduling or capturing a meeting. The AI work runs alongside it — chat that costs fewer tokens for the same quality, and an assistant that can pin things or hand you a shareable link to a document it referenced.
◆ Where it's heading
Tana is moving from a tool that stores what happened in a meeting to one that runs the meeting. Native Tana calls are now the default path on Today, with Zoom, Meet and Teams demoted to a capture case handled through desktop audio. The agent work points the same way: voices for meeting agents, AI that acts immediately rather than proposing changes for approval. The graph is becoming the substrate rather than the interface.
◆ Prediction
Given the pace of meeting-surface work and the AI moving from proposals to direct action, the next step is most likely deepening what agents can do during a live call. Nothing in these entries indicates how the token optimisation affects the underlying usage limits.
