Top Recommended Replacements
Logseq
FREEBest Overall Open-Source Alternative
Why we like it
100% privacy-focused and local-first; handles Markdown and Org-mode files; features a powerful 'Whiteboard' and built-in flashcards (SRS).
Keep in mind
Requires manual management of local files or a paid sync service for mobile; can occasionally lag with massive graphs.
Obsidian
FREEBest for Customization & Plugins
Why we like it
Huge community with 1,500+ plugins; stores notes as plain Markdown files on your device; incredibly fast and highly stable.
Keep in mind
Not a native 'outliner' like Roam (though plugins can mimic it); visual 'Canvas' is powerful but different from Roam's core workflow.
Tana
FREEBest for Structured Data & AI
Why we like it
Introduces 'Supertags' which turn notes into database objects; best-in-class AI integration (Tana AI) for automating workflows.
Keep in mind
Not open source; currently cloud-only; steeper learning curve due to its unique 'everything is a node' philosophy.
Anytype
FREEBest for Privacy & Aesthetic
Why we like it
Local-first with peer-to-peer sync (no central server required); beautiful object-oriented design; built-in templates for various use cases.
Keep in mind
The 'everything is an object' system can be confusing initially; sync between devices can sometimes be tricky without a cloud relay.
Affine.pro
FREEBest for Visual Collaboration
Why we like it
Seamlessly switches between a Page (doc), a Whiteboard (canvas), and a Database (table); high-performance open-source engine.
Keep in mind
Fewer community plugins compared to Obsidian; primarily focused on teams, which might feel like 'overkill' for solo users.
RemNote
FREEBest for Students & Life-Long Learners
Why we like it
Deeply integrates Spaced Repetition (flashcards) directly into your notes; excellent for breaking down complex subjects.
Keep in mind
Free tier has limits on some advanced 'Pro' study features; mobile app is less polished than its desktop counterpart.
Reflect
Best for Speed & Simplicity
Why we like it
Cleanest user interface in the PKM space; ultra-fast syncing; includes end-to-end encryption and a native iOS app.
Keep in mind
No permanent free tier; less 'extensible' than tools like Logseq or Obsidian; Apple-focused ecosystem.
Capacities
FREEBest for Object-Based Organizing
Why we like it
Uses 'Belief Mapping' to organize notes as Books, People, or Meetings; highly visual and intuitive for those who dislike folder hierarchies.
Keep in mind
Proprietary software; mobile app is still evolving; no offline-first local storage (cloud-based).
Heptabase
Best for Complex Visual Learning
Why we like it
The most advanced 'spatial' note-taking tool; allows you to map out connections on infinite whiteboards with deep nested cards.
Keep in mind
No free tier (subscription only); requires a mental shift to 'spatial' thinking, which isn't for everyone.
TiddlyWiki
FREEThe Ultimate 'Forever' Tool
Why we like it
Entire application is a single HTML file; survives for decades without needing an internet connection or a company to stay in business.
Keep in mind
Interface feels like 2005; extremely technical to customize; no modern 'mobile-first' experience.
