CommaFeed vs Smartsheet: 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 Smartsheet?
Smartsheet introduces a Contributor seat tier; rest of the stream is portal nav.
Almost everything in Smartsheet's tracked stream is portal navigation — Community link, Learning Center, customer stories, archived release notes index. The one substantive entry is the Contributor seat reaching general availability on April 30, positioned as 'best-in-class collaboration value' — i.e., a new pricing tier for users who participate in but don't author work.

◆ 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.

Smartsheet introduces a Contributor seat tier; rest of the stream is portal nav.
◆ Current state
Almost everything in Smartsheet's tracked stream is portal navigation — Community link, Learning Center, customer stories, archived release notes index. The one substantive entry is the Contributor seat reaching general availability on April 30, positioned as 'best-in-class collaboration value' — i.e., a new pricing tier for users who participate in but don't author work.
◆ Where it's heading
Smartsheet is using packaging, not features, as its visible motion right now: a Contributor seat sits below full-editor tiers and is built to expand seat counts inside accounts without forcing every collaborator onto a paid editor license. The rest of the stream offers no product-feature signal worth interpreting.
◆ Prediction
Expect Contributor-seat positioning to drive a B2B-style up-sell motion (more activated seats, eventually more upgrades) and follow-on packaging refinement around external collaborators and viewers. Real product moves are likely happening but not visible in this stream.
