Our suggestion based on what it does, not a feature-by-feature comparison.
Make money with it
Someone could sell ready-made Logseq templates or set-up and training services for people moving their notes into it.
An idea, not financial advice. Check the licence before charging for anything built on it.
Ways a business could use it
- Keep a private internal knowledge base, meeting notes and project plans without paying for a subscription tool
- Organise client research and tasks in one place to work faster as a freelancer
Can you use it commercially?
Free to use. Anything you distribute that includes it must be open-sourced under the same licence. Running it as an online service also counts, so a hosted version must offer its source.
Not legal advice. Read the project's licence file before building a product on it.
Getting it running
Download the installer for your operating system from the GitHub releases page, or try the web version at app.logseq.com; Linux has an installer script.
Follow the official instructions in the project README.
Things to check
- The new database version is in beta, and data loss is possible, so keep regular backups
- The mobile app and real-time collaboration sync are in alpha
- AGPL-3.0 licence has conditions if you modify and host it as a service
