Shortwave vs Rocket.Chat
A side-by-side editorial comparison of Shortwave and Rocket.Chat — release velocity, themes, recent moves, and the top alternatives to consider.
Shortwave vs Rocket.Chat: at a glance
What is Shortwave?
Shortwave keeps folding autonomy into the inbox, one AI action at a time.
Shortwave has moved decisively from an AI-assisted email client to an inbox that acts on the user's behalf. The assistant reads, drafts, organizes, and — via the Tasklet integration — triggers automated workflows across thousands of apps, with its work surfaced inside Shortwave rather than buried in Gmail. Every release since late 2024 has pushed more of the email workflow out of the user's hands and into the model's.
What is Rocket.Chat?
Rocket.Chat's 8.6 RC line adds self-hostable translation and a unified presence engine
This feed tracks Rocket.Chat GitHub release-candidate tags, and the top of the window is dominated by empty 8.6.0-rc.x and 8.5.0-rc.x 'Bump meteor version' cuts with the real content concentrated in the 8.6.0-rc.0 minor release. Note: this appears to be a duplicate product row of the other Rocket.Chat entry in the catalog (same RocketChat/Rocket.Chat repo, same releases, different slug/UUID); it is being classified independently off its own entries. Because these are RCs, capabilities are staged into a pre-release train rather than GA.

Shortwave
0.0COMMS
Shortwave keeps folding autonomy into the inbox, one AI action at a time.
◆ Current state
Shortwave has moved decisively from an AI-assisted email client to an inbox that acts on the user's behalf. The assistant reads, drafts, organizes, and — via the Tasklet integration — triggers automated workflows across thousands of apps, with its work surfaced inside Shortwave rather than buried in Gmail. Every release since late 2024 has pushed more of the email workflow out of the user's hands and into the model's.
◆ Where it's heading
The direction is a steadily widening action surface: MCP connectors to external tools, AI Memories, voice, and now trigger-based automation all frame email as an agent runtime rather than a reading pane. Model choices track the frontier closely — Claude 3.7 to Sonnet 4 to the 4.6 family — keeping capability tied to whatever the best available model can do. The team ships broadly across web, desktop, iOS, and Android each cycle.
◆ Prediction
The next moves most likely deepen autonomous execution — more trigger types and tighter loops where the assistant acts with less confirmation — rather than adding new surface features.

Rocket.Chat's 8.6 RC line adds self-hostable translation and a unified presence engine
◆ Current state
This feed tracks Rocket.Chat GitHub release-candidate tags, and the top of the window is dominated by empty 8.6.0-rc.x and 8.5.0-rc.x 'Bump meteor version' cuts with the real content concentrated in the 8.6.0-rc.0 minor release. Note: this appears to be a duplicate product row of the other Rocket.Chat entry in the catalog (same RocketChat/Rocket.Chat repo, same releases, different slug/UUID); it is being classified independently off its own entries. Because these are RCs, capabilities are staged into a pre-release train rather than GA.
◆ Where it's heading
The 8.6 cycle leans into self-hosted and privacy-controlled deployments: LibreTranslate for fully on-premise message auto-translation, Virtru as an external ABAC attribute store, and a unified presence engine with priority-based claims. In parallel there is a broad, deliberate migration of legacy DDP methods to REST endpoints (settings, spotlight, im.blockUser, e2e key requests, rooms.join), signaling an API-surface modernization ahead of a 9.0.0 removal.
◆ Prediction
The rc.x cadence points to an 8.6.0 GA cut once the release candidates settle. Expect the DDP-to-REST migration to continue toward the flagged 9.0.0 removal.
