A side-by-side editorial comparison of Misskey and Shortwave — release velocity, themes, recent moves, and the top alternatives to consider.
Misskey deleted its bundled machine-learning stack and made moderation someone else's service to run.
The visible history is essentially one release train, nine tags from 2026.7.0-beta.0 through the 2026.7.0 release, plus the first alpha of 2026.8.0. The defining change is that sensitive-media detection no longer runs inside Misskey: nsfwjs, TensorFlow.js, and the bundled NSFW model are gone from the codebase, replaced by HTTP calls to a separate sensitive-detector service. Operators who rely on the feature must stand that service up and point the control panel at it; if they do not, detection stops and all media is treated as non-sensitive.
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.

The direction is a smaller, more conventional Node application with its heavy and specialized dependencies pushed outside the process. The same release raises the Node floor to 22.22.2, 24.17.0 and 26.4.0, moves the Docker image to Node 26 on Debian trixie, and inherits a sharp requirement that breaks x86_64 CPUs without SSE4.2. The rebuilt logging layer points the same way, with one-line JSON output, per-domain levels, automatic credential redaction, and Sentry trace correlation, which is what an operator using standard tooling wants rather than what a self-contained appliance would ship.
Node 22 support is already flagged for removal, so the next train should drop it. Whether OpenTelemetry returns after being pulled between beta.6 and the release candidate is not something these entries settle.

Every release since late 2024 has pushed more of the email workflow out of the user's hands and into the model's.
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.
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.
