Double vs Prowlarr: at a glance
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.
What is Prowlarr?
Prowlarr's 3.0 pre-release keeps API keys out of logs and speeds up JSON parsing.
Prowlarr, the indexer manager for the *arr apps, is testing a 3.0 line on its develop branch. 3.0.0 moved the runtime to .NET 10 and Node 24, raised the Postgres minimum to 15 and added ZFS reflink support. 3.0.1 follows with a log fix that scrubs API keys in JSON-escaped query strings and a move to byte-level JSON deserialization.

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.
Prowlarr
5.0COLLAB
Prowlarr's 3.0 pre-release keeps API keys out of logs and speeds up JSON parsing.
◆ Current state
Prowlarr, the indexer manager for the *arr apps, is testing a 3.0 line on its develop branch. 3.0.0 moved the runtime to .NET 10 and Node 24, raised the Postgres minimum to 15 and added ZFS reflink support. 3.0.1 follows with a log fix that scrubs API keys in JSON-escaped query strings and a move to byte-level JSON deserialization.
◆ Where it's heading
The 3.0 cycle is a platform refresh rather than a feature release, and the follow-up builds are tightening it before it reaches stable. The pattern from 2.6 and 2.7, a pre-release then a stable build days or weeks later, suggests 3.0 will land on master once these fixes settle.
◆ Prediction
A stable 3.0 release on the master branch is the likely next step, carrying the .NET 10 and Postgres 15 requirements to all users.
