Converse.js vs Signal Desktop: at a glance
What is Converse.js?
Converse.js 14 lands OMEMO:2 — the browser XMPP client catches up on modern encryption.
Converse.js reached 14.0.0 in June 2026 after a tight beta train, and the release is defined by one thing: support for OMEMO:2, the current revision of XMPP's end-to-end encryption. The surrounding work is all encryption ergonomics — per-chat encryption state remembered across chat-close and re-login, an explicit error surfaced for undecryptable messages instead of silently dropping them, the toggle hidden on untrusted devices, and original filenames preserved on encrypted image download. New PubSub API methods for create, subscribe and unsubscribe round out the release.
What is Signal Desktop?
Signal Desktop can finally send contacts, ending a fix-only stretch of betas.
Signal Desktop ships a beta roughly weekly, and most builds since September have carried only generic fix notes. v8.34.0-beta.1 breaks that run with contact sharing from the desktop app, which previously required the phone, plus better handling and performance for connected audio devices. It follows v8.32.0-beta.1, which extended the unread filter into folders and search, and an October 1 build that cut CPU use in video calls.

Converse.js 14 lands OMEMO:2 — the browser XMPP client catches up on modern encryption.
◆ Current state
Converse.js reached 14.0.0 in June 2026 after a tight beta train, and the release is defined by one thing: support for OMEMO:2, the current revision of XMPP's end-to-end encryption. The surrounding work is all encryption ergonomics — per-chat encryption state remembered across chat-close and re-login, an explicit error surfaced for undecryptable messages instead of silently dropping them, the toggle hidden on untrusted devices, and original filenames preserved on encrypted image download. New PubSub API methods for create, subscribe and unsubscribe round out the release.
◆ Where it's heading
The project is closing the gap between having encryption and having usable encryption. Almost every OMEMO change in this cycle is about failure modes users previously had to guess at: a silently dropped message, an encryption toggle offered where it cannot work, an abandoned bundle that never self-healed. That is the work a client does when its encryption is no longer a demo but something people depend on daily. Dropping client-compress for native browser APIs points the same way — fewer bundled dependencies in a security-sensitive path.
◆ Prediction
Expect the 14.x line to settle into interoperability fixes as OMEMO:2 meets other XMPP clients in the wild, with the new PubSub API the most likely base for the next feature layer.
Signal Desktop
5.0COMMS
Signal Desktop can finally send contacts, ending a fix-only stretch of betas.
◆ Current state
Signal Desktop ships a beta roughly weekly, and most builds since September have carried only generic fix notes. v8.34.0-beta.1 breaks that run with contact sharing from the desktop app, which previously required the phone, plus better handling and performance for connected audio devices. It follows v8.32.0-beta.1, which extended the unread filter into folders and search, and an October 1 build that cut CPU use in video calls.
◆ Where it's heading
After a summer of group-admin features, polls and member search, the desktop app is closing gaps with mobile and firming up calls, notifications and inbox triage. Visible changes arrive every two or three betas, in small increments rather than a headline release.
◆ Prediction
Expect a fix-only beta or two next, then another small parity or call-quality change; the entries do not show a larger feature in progress.
