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 Contractbook?
Contract automation grows up: admin permission maps, 2FA, and forms that do their own arithmetic.
Contractbook released a batch of six changes on a single day covering three areas at once. Administration gets a company-wide Spaces access page answering who can reach which space and with what permission, plus OTP two-factor authentication at login. Contract creation gets calculation fields in forms that compute totals and pro-rated amounts and insert them into the document automatically. The AI side gets a new extraction model and a dedicated place to manage AI upload contract types, with built-in defaults now editable per company.
CommaFeed vs Contractbook: editorial side-by-side
CommaFeed
5.0COLLAB
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.
Contractbook
5.0COLLAB
Contract automation grows up: admin permission maps, 2FA, and forms that do their own arithmetic.
◆ Current state
Contractbook released a batch of six changes on a single day covering three areas at once. Administration gets a company-wide Spaces access page answering who can reach which space and with what permission, plus OTP two-factor authentication at login. Contract creation gets calculation fields in forms that compute totals and pro-rated amounts and insert them into the document automatically. The AI side gets a new extraction model and a dedicated place to manage AI upload contract types, with built-in defaults now editable per company.
◆ Where it's heading
The pattern is a product being fitted for larger customers: the access-visibility page is gated to Accelerate and Enterprise plans, group-level company permissions landed earlier in the year, and 2FA closes the obvious procurement objection. Meanwhile the AI features are moving from fixed behaviour toward configurable behaviour — extraction types are now a company's own list rather than the vendor's. Calculations remove the last common reason to edit a generated .docx by hand.
◆ Prediction
The admin thread points toward more permission surface — audit trails or per-space delegation would follow naturally from a page that already explains where each permission comes from. Nothing in these entries indicates how much extraction accuracy actually improved.
