Trilium Notes vs Mattermost
A side-by-side editorial comparison of Trilium Notes and Mattermost — release velocity, themes, recent moves, and the top alternatives to consider.
Trilium Notes vs Mattermost: at a glance
What is Trilium Notes?
The TriliumNext fork spent its early betas making the app trustworthy to install
Three beta releases from early 2025. The work is dominated by distribution and access concerns: signed Windows binaries obtained through a donated EV certificate, signed macOS builds, multi-factor authentication that required a database version bump, basic right-to-left content support, and repaired migration paths from the original Trilium. Nothing has been published to this feed since March 2025.
What is Mattermost?
Mattermost v12.1 puts bots and burn-after-reading messages under the same access rules.
Mattermost v12 shipped in parts: agents limited to the requesting user's access, Cross Guard for transfers across security domains, and user, device and channel attributes in access policy. A November 9 partnership pairs v12 with Arqit's quantum-safe device trust. v12.1 on November 13 extends attribute-based access control to bot accounts and to Burn-on-Read permissions, and Desktop v6.4 fixes Boards on subpath deployments.

◆ Current state
Three beta releases from early 2025. The work is dominated by distribution and access concerns: signed Windows binaries obtained through a donated EV certificate, signed macOS builds, multi-factor authentication that required a database version bump, basic right-to-left content support, and repaired migration paths from the original Trilium. Nothing has been published to this feed since March 2025.
◆ Where it's heading
These are the problems a fork inherits rather than chooses. Before adding features, the project had to make installs pass platform trust checks, let users migrate off the predecessor without an intermediate upgrade, and add authentication a self-hosted note store is expected to have. It is groundwork, done in the open, with contributors credited by name.
◆ Prediction
There is not enough recent activity to predict the next release. The feed has been silent for over a year, so whether the beta line continued elsewhere is the open question.
Mattermost
6.3COLLAB
Mattermost v12.1 puts bots and burn-after-reading messages under the same access rules.
◆ Current state
Mattermost v12 shipped in parts: agents limited to the requesting user's access, Cross Guard for transfers across security domains, and user, device and channel attributes in access policy. A November 9 partnership pairs v12 with Arqit's quantum-safe device trust. v12.1 on November 13 extends attribute-based access control to bot accounts and to Burn-on-Read permissions, and Desktop v6.4 fixes Boards on subpath deployments.
◆ Where it's heading
Each release closes another gap in one policy model for who and what can see a message: people, devices, channels, and now automation accounts and ephemeral messages. The audience stays defence and regulated buyers, and point releases are filling in v12 rather than starting new lines.
◆ Prediction
Further v12.x releases likely apply the same attribute rules to more objects, such as files, plugins or AI agent actions, following the pattern of v12.1.
