Fonoster vs Misskey: at a glance
What is Fonoster?
Fonoster parks its Deepgram diarization work after two 0.22.x stability patches.
Fonoster's last releases were September patches to the 0.22.x audio SDK: v0.22.13 made playStream resolve only after playback completes, and v0.22.14 caught unhandled rejections on hangup that could crash the Node.js process. The newest item is not a release but an archive tag parking a Deepgram streaming diarization speaker filter written against the old apiserver.
What is Misskey?
Misskey offloads its embedded ML stack to external services and ships a critical security patch in consecutive major releases.
Misskey maintains a monthly major release cadence with an explicit beta/RC pipeline before stable releases. The 2026.7.0 cycle's defining architectural change was removing the bundled TensorFlow/nsfwjs NSFW detection in favor of an external HTTP service—substantially reducing installation complexity and ML dependency weight for self-hosters. The 2026.9.0 stable release carried critical security vulnerability fixes requiring urgent instance operator updates.
Fonoster vs Misskey: editorial side-by-side
Fonoster
2.5COMMS
Fonoster parks its Deepgram diarization work after two 0.22.x stability patches.
◆ Current state
Fonoster's last releases were September patches to the 0.22.x audio SDK: v0.22.13 made playStream resolve only after playback completes, and v0.22.14 caught unhandled rejections on hangup that could crash the Node.js process. The newest item is not a release but an archive tag parking a Deepgram streaming diarization speaker filter written against the old apiserver.
◆ Where it's heading
The project is in maintenance mode on 0.22.x, with no new feature surface since September. Archiving the diarization work suggests speaker-aware transcription isn't shipping on the old apiserver path.
◆ Prediction
It's unclear when a 0.23.0 feature release lands; the entries show a month-long gap and parked rather than shipped speech features.
Misskey
5.0COMMS
Misskey offloads its embedded ML stack to external services and ships a critical security patch in consecutive major releases.
◆ Current state
Misskey maintains a monthly major release cadence with an explicit beta/RC pipeline before stable releases. The 2026.7.0 cycle's defining architectural change was removing the bundled TensorFlow/nsfwjs NSFW detection in favor of an external HTTP service—substantially reducing installation complexity and ML dependency weight for self-hosters. The 2026.9.0 stable release carried critical security vulnerability fixes requiring urgent instance operator updates.
◆ Where it's heading
Misskey is reducing its embedded dependency footprint, making instances lighter and more modular. Offloading NSFW detection to a configurable external service is the clearest example: instances that don't need content moderation avoid the ML stack entirely, while those that do can point to a dedicated service. This trend toward externalizing heavy subsystems continues the project's decentralized, operator-customizable philosophy.
◆ Prediction
Continued dependency reduction and broader ActivityPub federation improvements are likely. The 2026.8.0 alpha cycle signals the next major feature set is in active development, though content is not yet visible from the alpha.
