A side-by-side editorial comparison of Converse.js and Session — release velocity, themes, recent moves, and the top alternatives to consider.
Converse.js vs Session: at a glance
What is Converse.js?
Converse.js 14.0.1 fixes OMEMO:2 group decryption broken by Chromium 153.
Converse.js shipped 14.0.0 in June with OMEMO:2, the current revision of XMPP's end-to-end encryption, plus fixes that make encryption state and errors visible. 14.0.1 in October fixes OMEMO:2 group messages that stopped decrypting in Chromium 153, a bug that also skipped a sender check.
What is Session?
Session survived its funding scare; now Pro is on hold and Protocol v2 is the bet.
Session's 2026 started with a cofounder's appeal warning the project might not continue, followed in June by news that community support had restored its runway. Since then the feed has tracked Session Pro: release preparation in August, a proposed change to Pro's tokenomics, a beta submitted to app stores in September, then in October a pause on the Pro launch while talks with an allied privacy ecosystem continue. Infrastructure work continued, with lighter Session Node software in mid-October.

Converse.js
2.5COMMS
Converse.js 14.0.1 fixes OMEMO:2 group decryption broken by Chromium 153.
◆ Current state
Converse.js shipped 14.0.0 in June with OMEMO:2, the current revision of XMPP's end-to-end encryption, plus fixes that make encryption state and errors visible. 14.0.1 in October fixes OMEMO:2 group messages that stopped decrypting in Chromium 153, a bug that also skipped a sender check.
◆ Where it's heading
The project is in a stabilisation phase on the 14 line, with encryption correctness as the main concern. Releases are months apart.
◆ Prediction
Expect further 14.0.x patches for encryption and browser compatibility; no next major is signalled.
Session
5.0COMMS
Session survived its funding scare; now Pro is on hold and Protocol v2 is the bet.
◆ Current state
Session's 2026 started with a cofounder's appeal warning the project might not continue, followed in June by news that community support had restored its runway. Since then the feed has tracked Session Pro: release preparation in August, a proposed change to Pro's tokenomics, a beta submitted to app stores in September, then in October a pause on the Pro launch while talks with an allied privacy ecosystem continue. Infrastructure work continued, with lighter Session Node software in mid-October.
◆ Where it's heading
Protocol v2, adding forward secrecy, post-quantum encryption and better linked-device handling, is now the main technical thread, with an invite-only alpha planned. Pro's monetisation model is in flux, so the revenue side remains unresolved.
◆ Prediction
Unclear whether Pro launches in its current form; the next concrete step is more likely a Protocol v2 alpha announcement.
