Mattermost vs Trilium Notes
A side-by-side editorial comparison of Mattermost and Trilium Notes — release velocity, themes, recent moves, and the top alternatives to consider.
Mattermost vs Trilium Notes: at a glance
What is Mattermost?
Every v11 release pushes ABAC further out; the blog sells the air-gap story around it.
Mattermost ships a v11.x release roughly monthly, and each one extends attribute-based access control another layer: v11.9 reached channel-level policies and ranked attributes, v11.10 adds team-level ABAC membership and native user attributes. Between releases the feed is marketing content aimed at defense, federal, and other air-gapped buyers. The product work and the publishing calendar are pulling in the same direction.
What is Trilium Notes?
A local-first note app hardens its imports and keeps AI optional
Trilium, now maintained as the TriliumNext community fork, is a local-first hierarchical note application on a steady monthly point-release cadence. Recent work centers on import fidelity, note-type expansion (spreadsheets and OCR in 0.103), security patches, and a pragmatic LLM stance: it removed bundled LLM integration in 0.102.0, then reintroduced a lighter, provider-backed model selector.

Mattermost
5.0COLLAB
Every v11 release pushes ABAC further out; the blog sells the air-gap story around it.
◆ Current state
Mattermost ships a v11.x release roughly monthly, and each one extends attribute-based access control another layer: v11.9 reached channel-level policies and ranked attributes, v11.10 adds team-level ABAC membership and native user attributes. Between releases the feed is marketing content aimed at defense, federal, and other air-gapped buyers. The product work and the publishing calendar are pulling in the same direction.
◆ Where it's heading
ABAC is being built out as the organizing primitive — first channels, now teams, with user attributes moving from an integration concern into the platform itself. The surrounding posts on agentic AI in disconnected environments read as demand-shaping for the AI features shipping in the same releases. Expect the two lines to converge on running agents inside a network that cannot call out.
◆ Prediction
The next v11 release should extend ABAC to a further scope or add policy administration tooling, and the agent features will keep being framed around operating without external model APIs.
Trilium Notes
5.0COLLAB
A local-first note app hardens its imports and keeps AI optional
◆ Current state
Trilium, now maintained as the TriliumNext community fork, is a local-first hierarchical note application on a steady monthly point-release cadence. Recent work centers on import fidelity, note-type expansion (spreadsheets and OCR in 0.103), security patches, and a pragmatic LLM stance: it removed bundled LLM integration in 0.102.0, then reintroduced a lighter, provider-backed model selector.
◆ Where it's heading
The fork is stabilizing and broadening ingest and interop — robust OneNote migration with device-code web authentication and multi-hour token refresh — while keeping AI optional and provider-driven rather than baked in. The direction is a dependable self-hosted knowledge base that reclaims data locked in other tools.
◆ Prediction
Expect continued import and format-fidelity work plus incremental, provider-dynamic LLM options rather than a bundled AI push; official mobile and multi-user remain community-demand items gated on funding.
