SiYuan has attracted 7% as many forks as stars, Logseq 6%. SiYuan was the more recently maintained of the two, and both are self-hostable with no licence fee. The two share 4 topic tags (knowledge-base, local-first, markdown, note-taking), so they are genuine substitutes rather than adjacent tools.
Two open source projects, one decision. Both are free and self-hostable — the differences are community size, license terms, language stack and release pace.
