A side-by-side editorial comparison of Syncthing and Double — release velocity, themes, recent moves, and the top alternatives to consider.
Syncthing 2.1.7 hits a fourth release candidate as fixes move from protocol to sync logic.
Syncthing's 2.1 line added device and folder groups, HTTP CONNECT proxies, optional block indexing and configurable GUI sessions. Every tracked entry since then is a patch release candidate. 2.1.6 took four RCs, and 2.1.7 is now on rc.4, which adds sync-model fixes for metadata shortcuts, parent ownership and receive-only folders on top of rc.3's protocol validation.
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.

The project is stabilising the SQLite backend that came with 2.x and tightening the network protocol, and rc.4 extends that to correctness fixes in the sync model itself. Releases go through several RCs before going stable, roughly every two to three weeks.
Expect 2.1.7 stable after rc.4, followed by more 2.1.x patches on SQLite and sync correctness. The entries don't show what 2.2 will bring.

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.
Expect more agent templates and recorder support for other client systems, plus wider Xero coverage after the US bank feeds launch.
