Comparison · Jujutsu
Jujutsu (jj) is a Git-compatible version control system that treats the working copy as a change, records every operation in an undoable log, and stores conflicts as data. Here is how it compares with Git and with TOVIO's design, row by row.
native / first-class partial or workaround not documented as native
Jujutsu and Git cells reflect a 2026 snapshot, checked on , of each tool's publicly documented behavior. TOVIO cells reflect the v1 design target — TOVIO is pre-1.0, unpublished, and not yet independently audited. See the launch gates and what ships today and the sources and qualifications.
Read each complete row. Partial support includes limited coverage or extensions. An em dash means no native mechanism was documented in the reviewed sources, not that every external integration was ruled out. Local commits do not imply a fully distributed architecture. Direct binary storage does not establish asset-size limits, transfer efficiency, or performance.

Documentation checks, not independent execution tests of every product. Choose a tool for its scope and official references.
Sparse checkout is native. Git stores binary bytes without LFS, but large-asset storage and transfer have different tradeoffs from a dedicated asset workflow. Reflogs retain ref movements, not complete working-copy snapshots. Shallow and partial clones are exceptions to full-history cloning.
Stable change identity, stored conflicts, and operation-log restore are native. Bookmark updates merge during fetch, but divergent targets can leave a conflicted bookmark requiring a decision. Git-backed storage can hold binaries; this does not imply a dedicated large-asset store or built-in LFS workflow.
The column describes the v1 design target under supported profiles, not general availability. Undo depends on supported, retained operations. Semantic context is advisory; behavioral rollback records supplied AI configuration, not a running model. Signing-required repositories currently hold divergent lanes rather than automatically reconciling them. The Apache-2.0 core and commercial Forge have different licenses.
