BookStack vs Double: at a glance
What is BookStack?
BookStack's release log is now mostly security patches between feature drops.
BookStack ships a feature release roughly every four months and fills the gaps with point releases that are almost all security fixes. The latest feature release, v26.09, added a customizable interface layout system and scoped search API endpoints; every point release since has closed permission and visibility holes.
What is Double?
Double turns a recorded Chrome session into an agent that repeats the task.
Double is an accounting-practice platform built around the Ask Double assistant. Autoclose, an October 29 add-on at $500 a month, lets agents run the month-end close, and November 5 extended Ask Double to allocations, bank matching and 1099 prep. The November 12 release lets accountants record a task in the Double Chrome extension and turn it into an agent, adds bank feeds for US Xero clients, per-user caps on AI credits and new permission choices for agent actions.
BookStack vs Double: editorial side-by-side
BookStack
5.0COLLAB
BookStack's release log is now mostly security patches between feature drops.
◆ Current state
BookStack ships a feature release roughly every four months and fills the gaps with point releases that are almost all security fixes. The latest feature release, v26.09, added a customizable interface layout system and scoped search API endpoints; every point release since has closed permission and visibility holes.
◆ Where it's heading
The recurring vulnerability theme is permission edge cases around drafts, the recycle bin and attachments, which suggests a steady external research effort probing the permission model. Feature work is leaning toward customization and API reach while the security cadence keeps the core trustworthy for self-hosters.
◆ Prediction
Expect at least one more security point release before the next feature version, likely again touching drafts, attachments or recycle-bin permissions, since those areas recur in nearly every patch.
Double
8.8COLLAB
Double turns a recorded Chrome session into an agent that repeats the task.
◆ Current state
Double is an accounting-practice platform built around the Ask Double assistant. Autoclose, an October 29 add-on at $500 a month, lets agents run the month-end close, and November 5 extended Ask Double to allocations, bank matching and 1099 prep. The November 12 release lets accountants record a task in the Double Chrome extension and turn it into an agent, adds bank feeds for US Xero clients, per-user caps on AI credits and new permission choices for agent actions.
◆ Where it's heading
Double is moving from an assistant that answers to agents that do recurring work, and is now letting firms create those agents by showing rather than configuring. Usage caps, permission levels and a web-browsing switch that is off by default show it adding controls as agents get more reach.
◆ Prediction
Expect more agent templates and recorder support for other client systems, plus wider Xero coverage after the US bank feeds launch.
