Delta Chat vs Misskey: at a glance
What is Delta Chat?
Delta Chat patches a Team Profile regression and moves its Tauri build out of the repo.
The desktop client runs on a roughly weekly cadence. 2.59.0 added reactions on channel posts, a hideable window menu bar and experimental Team Profiles; 2.59.1 followed eight days later to fix messages staying unread when read from another device, a regression affecting profiles created with Team Profile enabled. The same patch adds Arabic, Telugu and Slovenian, and moves the Tauri edition to its own repository.
What is Misskey?
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.
Delta Chat vs Misskey: editorial side-by-side
Delta Chat
5.0COMMS
Delta Chat patches a Team Profile regression and moves its Tauri build out of the repo.
◆ Current state
The desktop client runs on a roughly weekly cadence. 2.59.0 added reactions on channel posts, a hideable window menu bar and experimental Team Profiles; 2.59.1 followed eight days later to fix messages staying unread when read from another device, a regression affecting profiles created with Team Profile enabled. The same patch adds Arabic, Telugu and Slovenian, and moves the Tauri edition to its own repository.
◆ Where it's heading
The client is in a broadening phase - channel reactions, Team Profiles as an opt-in experiment, and continued keyboard and accessibility work carried forward from 2.53.0. Splitting out the Tauri edition indicates the Electron build remains the one that ships while the alternative develops at its own pace instead of gating releases. Language coverage keeps widening, which for this project is as much a distribution decision as a localisation one.
◆ Prediction
The 2.59.1 notes promise a more elaborate fix for the Team Profile unread bug in the coming weeks, so expect that in the next minor rather than another patch.
Misskey
6.3COMMS
Misskey deleted its bundled machine-learning stack and made moderation someone else's service to run.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
