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.

What is Stalwart?

Stalwart adds full SCIM v2 provisioning and 24-language calendar support as its standards coverage extends further than most commercial mail servers.

Stalwart is maintaining a weekly-or-faster release cadence, with alternating feature releases and dense bug-fix releases. The v0.16.20 release landed full SCIM v2 (Enterprise) including cursor-based pagination and the IPSIE lifecycle profile, conference links in calendar invites, and 24 new calendar interface translations. Below the feature line, the project is steadily closing correctness gaps across JMAP, CalDAV, IMAP, and MTA — many of them edge-case RFC compliance issues.

Misskey vs Stalwart: editorial side-by-side

M
Misskey
COMMS
5.0

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.

S6.3

Stalwart adds full SCIM v2 provisioning and 24-language calendar support as its standards coverage extends further than most commercial mail servers.

◆ Current state

Stalwart is maintaining a weekly-or-faster release cadence, with alternating feature releases and dense bug-fix releases. The v0.16.20 release landed full SCIM v2 (Enterprise) including cursor-based pagination and the IPSIE lifecycle profile, conference links in calendar invites, and 24 new calendar interface translations. Below the feature line, the project is steadily closing correctness gaps across JMAP, CalDAV, IMAP, and MTA — many of them edge-case RFC compliance issues.

◆ Where it's heading

Stalwart is building toward parity with commercial enterprise mail servers on identity federation and provisioning (SCIM v2, VAPID for web push, DMARCbis/DKIM2 already landed). The pace of RFC implementation is unusually aggressive for an open-source project; the combination of JMAP, CalDAV, IMAP UIDONLY/UIDBATCHES, and SCIM v2 positions it as a viable self-hosted alternative for organizations that need standards compliance without vendor lock-in.

◆ Prediction

WebAuthn/passkey-based authentication and improved multi-tenant administration tooling are the most likely next capability additions, given the current trajectory toward enterprise identity management.
