CommaFeed vs Double: 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 Double?
Double is moving the whole bookkeeping workflow into a chat assistant, one billable task per week.
Double ships weekly, and for two months straight nearly every release has been another accounting task absorbed into Ask Double: transactions in late June, live spreadsheets, AI workpapers, metrics creation, voice input, and now Connections to outside tools. The assistant has gone from answering questions about the books to creating the artifacts accountants bill for. The most recent entry breaks the pattern — role-based restrictions on who can edit client properties — which is the administrative counterweight to everything else.

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.
Double
7.5COLLAB
Double is moving the whole bookkeeping workflow into a chat assistant, one billable task per week.
◆ Current state
Double ships weekly, and for two months straight nearly every release has been another accounting task absorbed into Ask Double: transactions in late June, live spreadsheets, AI workpapers, metrics creation, voice input, and now Connections to outside tools. The assistant has gone from answering questions about the books to creating the artifacts accountants bill for. The most recent entry breaks the pattern — role-based restrictions on who can edit client properties — which is the administrative counterweight to everything else.
◆ Where it's heading
The strategy is to make Ask Double the primary interface and reduce the app's tab-by-tab surface to a system of record behind it. Two constraints are being addressed in parallel: the assistant needed to reach data Double does not hold, which Connections solves, and firms needed guardrails before handing an assistant this much reach, which the permissions work starts. Exposing metrics through both Ask Double and an MCP/API endpoint suggests Double expects agents outside its own product to drive the platform too.
◆ Prediction
Connections should exit private beta and expand its connector list, since it is the dependency for the cross-tool briefings Double is pitching. Expect the permissions model to keep hardening in step with each new thing the assistant is allowed to create.
