Obsidian vs TriliumNext Notes

Obsidian is a note-taking app for keeping notes and building a personal knowledge workspace. Its core app is free, has no sign-up requirement, and stores notes on the user's device so they remain available offline. It runs on Windows, macOS, Linux, iOS, Android, and as a Chrome extension. Canvas provides an open workspace for research, brainstorming, diagrams, and ideas; thousands of plugins and an open API allow workflow customization. Shared vaults support team work with real-time updates. Sync adds synchronization and version history: Standard costs $5 per user per month billed annually, with one vault, 1 GB of storage, a 5 MB maximum file size, and one month of history. Plus costs $10 per user per month billed annually, with 10 vaults, 10 GB, a 200 MB maximum file size, and 12 months of history. Publish is $10 per site per month billed annually and includes up to 4 GB hosting per site. It offers themes, custom domains, password protection, and SEO optimization.

TriliumNext Notes is a free, open-source application for taking notes and maintaining a personal knowledge base. It uses an outliner structure in which notes can be nested hierarchically and placed in multiple locations. Supported note types include text, Markdown, code, spreadsheets, canvases, Mermaid diagrams, mind maps and files. Collections can present the same material as calendars, tables, Kanban boards, geomaps, presentations or dashboards. Full-text search can inspect image and PDF text through OCR. Notes can be imported from Markdown, HTML and OPML and exported to those formats. Self-hosted or cloud instances synchronize across devices and provide mobile browser access through a PWA; no official mobile app is provided. JavaScript supports widgets and scheduled or event-driven scripts. Optional AI connections use your own provider keys. Protected notes use AES-128 CBC, while metadata remains unencrypted. The software is designed for one user, not simultaneous shared editing.
