Roam Research
From ~$15 per mo (annual ~$8.33/mo)
Obsidian
Free (personal) / Sync ~$4 per mo
Roam Research popularized networked thought with an outliner-first, hosted experience and deep block linking. Obsidian is a local-first, plain-text vault you own, with linking and a huge plugin ecosystem. Roam wins on outliner-native linking; Obsidian wins on ownership, price, and plugins.
Pick Roam Research if you want a hosted, outliner-first tool with the deepest native block-linking workflow.
Pick Obsidian if you want to own your notes locally, work offline, and extend them with a huge plugin ecosystem at a lower price.
Roam Research and Obsidian both champion networked thinking, where ideas connect through bidirectional links, but their models differ. Roam is hosted and outliner-first, and it popularized the whole category with frictionless block linking and daily notes that many power users love. Obsidian stores plain-text Markdown on your own device, so you own your data and can work offline, and it extends through one of the largest plugin ecosystems around — including community plugins that replicate Roam-style workflows.
On price, Roam costs around $15 a month (cheaper annually) while Obsidian is free for personal use with optional Sync around $4 a month. The choice is mostly hosted, outliner-native networked notes (Roam) versus an owned, local-first, plugin-rich vault (Obsidian).

Things neither product's marketing page leads with.
Roam is outliner-native and beloved for networked thought, but it is hosted, pricier, and you do not own local files.
Obsidian is cheaper, local-first, and plugin-rich, but its outliner workflow relies on plugins rather than being native.
For native networked outlining Roam appeals; for ownership and value Obsidian usually wins.
