SimpleX Chat vs Rocket.Chat: at a glance
What is SimpleX Chat?
SimpleX Chat stabilizes its 6.5 line, routing link previews through SOCKS for privacy.
SimpleX Chat, the messenger built without user identifiers, is rolling out its 6.5.x line. Recent changelog activity is dominated by per-architecture armv7a build tags that merge stable into the Android branch — release plumbing rather than new capability. The one substantive change sits in the 6.5.0 beta: routing link previews through the SOCKS proxy when enabled, plus a UI to switch toolbar position.
What is Rocket.Chat?
Rocket.Chat deepens enterprise ABAC and quietly preps a post-Meteor client transport
Rocket.Chat is mid-cycle on 8.5.0, with three release candidates shipped in nine days — only rc.0 carries substantive changes, while rc.1 and rc.2 are stabilization. The prior 8.4.0 cycle landed April 20 with cold-storage archiving for read receipts and new media-call REST endpoints. Cadence is steady: substantive minor releases every five to six weeks, each followed by multi-RC stabilization.

SimpleX Chat
5.0COMMS
SimpleX Chat stabilizes its 6.5 line, routing link previews through SOCKS for privacy.
◆ Current state
SimpleX Chat, the messenger built without user identifiers, is rolling out its 6.5.x line. Recent changelog activity is dominated by per-architecture armv7a build tags that merge stable into the Android branch — release plumbing rather than new capability. The one substantive change sits in the 6.5.0 beta: routing link previews through the SOCKS proxy when enabled, plus a UI to switch toolbar position.
◆ Where it's heading
The cadence reflects a stabilization phase on 6.5 — frequent point tags across architectures over a stable feature base. The privacy-by-default ethos still shows in the lone real feature, SOCKS-proxied previews. Expect continued 6.5.x hardening rather than directional change.
◆ Prediction
Next moves are likely more 6.5.x point releases and architecture builds; the beta channel, not the armv7a stable tags, is where the next feature batch will surface.

Rocket.Chat deepens enterprise ABAC and quietly preps a post-Meteor client transport
◆ Current state
Rocket.Chat is mid-cycle on 8.5.0, with three release candidates shipped in nine days — only rc.0 carries substantive changes, while rc.1 and rc.2 are stabilization. The prior 8.4.0 cycle landed April 20 with cold-storage archiving for read receipts and new media-call REST endpoints. Cadence is steady: substantive minor releases every five to six weeks, each followed by multi-RC stabilization.
◆ Where it's heading
Two arcs run through recent releases. The first is enterprise hardening: ABAC tooling deepens release-on-release (tab-visibility permissions, Virtru as an external PDP, room-attribute access for apps), scalability levers land as opt-in environment variables (USE_ROOM_SEARCH_INDEX, Cold Storage for Read Receipts), and security work is constant — phishing-resistant server-side OAuth, XSS sanitization in markdown, multiple security hotfixes. The second is a long unwind from the Meteor era: internal apps-engine APIs swapped to the public @rocket.chat/apps package, an experimental SDK-over-DDP transport gated by the dormant Use_RC_SDK flag, and a skipTranspile flag previewing the Babel removal slated for 9.0.0.
◆ Prediction
9.0.0 is the next architectural moment — full Babel removal, likely SDK-over-DDP graduated past the experimental flag, and continued apps-engine consolidation. Expect ABAC features to keep landing every cycle until attribute-based access becomes the default model rather than an opt-in admin panel.
