Why people self-host Trilium Notes
Trilium Notes is strongest for personal knowledge bases with deep hierarchy, rich notes, scripting, and long-running local-first use. It suits researchers who want structure and ownership more than team collaboration.
The tradeoff is that the interface and model are idiosyncratic. Export regularly and test restore of the database before writing irreplaceable notes.
Deployment notes
Trilium Notes is listed with support signals for linux, docker, windows, macos. Check the upstream documentation before exposing it to the internet, review authentication defaults, and keep backups outside the primary host.
