# Logseq vs SiYuan: graph-version risk, block references and export boundaries

> **AI Summary:** Logseq and SiYuan are compared for a knowledge worker evaluating linked notes without assuming that exports or new graph versions preserve the whole workspace. For Logseq, choose the graph type first: the inspected README labels the DB version beta, the new mobile app/RTC alpha, and warns of possible data loss. Documentation-only, checked 2026-10-26; operating constraints and unequal source scope limit any conclusion. [logseq-docs] [siyuan-docs]

## Knowledge-organization model
Logseq
- Logseq describes knowledge management with PDF annotation and task-management functions. (vendor-documented) [logseq-docs]
SiYuan
- SiYuan describes personal knowledge management with block-level references and Markdown WYSIWYG editing. (vendor-documented) [siyuan-docs]

## Data or exchange mechanism
Logseq
- Logseq’s README describes DB graphs in a DB version labeled beta. (vendor-documented) [logseq-docs]
SiYuan
- SiYuan lists export to standard Markdown with assets. (vendor-documented) [siyuan-docs]

## Release or entitlement condition
Logseq
- Logseq labels the DB version beta and its new mobile app and RTC alpha, warning that data loss is possible. (vendor-documented) [logseq-docs]
SiYuan
- SiYuan states that some features are available only to paid members. (vendor-documented) [siyuan-docs]

## Conclusion
For Logseq, choose the graph type first: the inspected README labels the DB version beta, the new mobile app/RTC alpha, and warns of possible data loss. Evaluate SiYuan around the required block relationships and export artifacts while checking paid-feature access. Neither source establishes lossless workspace migration; use nonessential copies and verified recovery steps before moving valuable notes. [logseq-docs] [siyuan-docs]

## Decision context and selection scope
- Target decision: a knowledge worker evaluating linked notes without assuming that exports or new graph versions preserve the whole workspace. Logseq and SiYuan were selected because their documented workflows offer relevant ways to address that decision. This is not a market-wide shortlist, identical-edition benchmark or recommendation for every organization. Sources identify each project revision; current commercial plans, installed versions and delivered behavior were not compared. (editorial-opinion) [logseq-docs] [siyuan-docs]

## Practical differences / Conditions that change the choice
- Logseq: A knowledge worker can evaluate Logseq’s organization model, but the graph/version decision comes before importing valuable notes. The documented DB beta and data-loss warning make a dedicated, recoverable test graph the appropriate scope for investigating that new workflow. Boundary: Logseq explicitly warns that DB-version data loss is possible; the new mobile app and RTC are alpha. The general Markdown/Org-mode description must not be read as a guarantee that DB graphs have the same storage, sync or migration behavior as file graphs. (editorial-opinion) [logseq-docs]
- SiYuan: A writer using linked blocks can consider SiYuan when references, assets and exports must support an actual writing task. Export should be judged by what survives in the receiving workflow, while hosting, sync and membership access are verified independently. Boundary: A standard-Markdown export option does not establish reversible preservation of every block reference, database view or application-specific relationship. The paid-feature notice also prevents treating the whole feature list as a universal entitlement or zero-cost sync plan. (editorial-opinion) [siyuan-docs]

## Use-case recommendation / A fair trial
- Proposed Logseq and SiYuan comparison, not performed: Use a small disposable set of linked notes, an attached asset, a task and one structured view where relevant. Record Logseq’s exact graph/build choice and SiYuan’s edition and export mode. Inspect links and assets outside the application, then restore or reimport a separate copy and document lost relationships. Keep the Logseq DB/mobile/RTC experiment away from an irreplaceable live graph. (editorial-opinion) [logseq-docs] [siyuan-docs]

## Evidence and comparison limitations
- For Logseq versus SiYuan, the matrix records what the selected official documents actually say. A more detailed source for one product does not prove that the other lacks an unmentioned capability. Different releases, plugins, editions and deployment choices can change the decision. No timing, cost, security or productivity winner was measured; retain a no-supported-winner conclusion for those criteria until matched artifacts exist. (editorial-opinion) [logseq-docs] [siyuan-docs]

## FAQ / Does Markdown support establish a lossless Logseq-to-SiYuan migration?
- Logseq and SiYuan: No. Logseq’s file/DB distinction and SiYuan’s application relationships have separate storage and recovery implications. Compare the exact exported artifacts and restored links; beta/alpha data-loss warnings and edition conditions must remain part of the decision. (editorial-opinion) [logseq-docs] [siyuan-docs]

## Further reading
- Use the official source references for both Logseq and SiYuan; the documented trial and decision boundaries above define what still needs verification. Related single-product articles on this site provide different editorial purposes, not additional independent product tests or a substitute for current project guidance. (editorial-opinion) [logseq-docs] [siyuan-docs]

## Methodology
Official project documentation was retrieved on 2026-10-26 (Asia/Saigon), retained with integrity hashes and matched to literal excerpts under Editorial Standard 1.3, revision r1. Product assertions are attributed documentation; suitability and proposed trials are editorial reasoning from those premises. Repository commits identify source scope, not an installed release. No product account or hands-on test was used; site-build checks verify publishing output only.

## Limitations
- Logseq: Logseq explicitly warns that DB-version data loss is possible; the new mobile app and RTC are alpha. The general Markdown/Org-mode description must not be read as a guarantee that DB graphs have the same storage, sync or migration behavior as file graphs.
- SiYuan: A standard-Markdown export option does not establish reversible preservation of every block reference, database view or application-specific relationship. The paid-feature notice also prevents treating the whole feature list as a universal entitlement or zero-cost sync plan.
- Current commercial prices, service quotas, paid support and total operating cost were not verified. Source availability does not establish a free hosted service or zero operating expense.
- No installation, account access, hands-on task, benchmark, security review or recovery experiment was performed. Proposed trials are recommendations, not observed outcomes.
- Sources are project-controlled documentation at recorded revisions. A source-matched description is not independent behavior verification; absent evidence is not proof that a capability is absent.
