Litmaps alternatives
1 open-source project that already does this job. Free to use - not free to run, which is what the numbers on the right are for.
The projects
What you give up either way
- Proprietary indexed catalogue (270+ million papers) and its coverage/quality
- Scale and reliability of production search/index infrastructure
- Built-in Zotero one-click sync and polished UI refinements
- Institutional/team licensing and enterprise support
An open-source project doing the core job proves a replacement is possible. It does not prove it matches Litmaps, and it does not prove anyone has run it for a month. How we decide.
