Git History Graph Generator
Paste git log --graph, git log --oneline or a plain commit list and get a proper commit graph — lanes, branch colours, merge curves, refs and messages — drawn as SVG and exportable as PNG or SVG.
Commit log
Accepted formats
- git log --graph — leading gutter of * | \ / _, then a hash, optional (HEAD -> main, origin/main, tag: v1.0) decorations, then the subject. Parent links are reconstructed from the lane geometry.
- git log --oneline — hash subject per line, with optional (parent: abc1234) and --decorate output. Without explicit parents a linear chain is inferred from the row order.
- Simple list — hash|parent1,parent2|author|2026-01-02|Subject, or the same fields separated by tabs, or a bare subject per line (a synthetic hash is generated).

Summary
- Commits parsed

- Format used
- graph (auto)
All 8 parent link(s) were reconstructed from the ASCII lane geometry. 1 commit(s) look like roots (their lane does not continue below). Merge edges can only be recovered when the gutter shows a branch lane; if a merge is missing, use the merge sample or the simple-list format with explicit parents.
4 lines or links could not be used:
- Line 3: no commit hash found — skipped.
- Line 7: no commit hash found — skipped.
- Line 9: no commit hash found — skipped.
- Line 12: no commit hash found — skipped.

Every entry is a ref found in the input; the count is how many commits in this window are reachable from it. Lanes that carry no ref still get a palette colour.
About this tool
This generator reads three log shapes — the ASCII --graph gutter, --oneline and a plain commit list — rebuilds parent relationships including merges, then lays out lanes, merge curves and refs as one crisp SVG that exports to PNG at 2× or to editable SVG. Every commit in the window is rendered, up to 500; parsing, layout and both exports run entirely in your browser, so your repository history is never uploaded anywhere.
