Obsidian vs Roam Research
Side-by-side comparison of features, pricing, ratings, and alternatives.
Obsidian is a note-taking and personal knowledge management app built around plain markdown files stored locally on your device. Rather than a rigid folder hierarchy, Obsidian encourages a networked structure through bidirectional links, backlinks, and an interactive graph view that visualizes how notes connect. Because notes are just markdown files on disk, Obsidian is fast, works fully offline, and keeps your data portable - there is no proprietary lock-in. A large community plugin ecosystem extends the core app with everything from spaced-repetition flashcards to kanban boards and calendar views. Obsidian Sync and Obsidian Publish are optional paid add-ons for cross-device syncing and publishing notes as a website, but the core app is free for personal use.
Roam Research is a web‑based note‑taking platform built around bi‑directional links and a graph view, allowing users to create a web of interconnected ideas. Its daily notes page encourages a habit of capturing thoughts as they happen, while the query language lets you retrieve information across the entire knowledge base. Designed for researchers, writers, and knowledge workers, Roam supports markdown, collaborative editing, and real‑time syncing across devices. The platform’s open API enables custom integrations and automation, extending its capabilities beyond personal use.
Free for personal use; commercial licenses and sync/publish are paid add-ons.

4.0 (2)Highly recommend Obsidian
Obsidian has quickly become part of our daily workflow. Extremely fast and works offline. One minor gripe: sync/publish cost extra, but it hasn't been a dealbreaker. Would recommend to anyone considering it.
