jj log is a core command in Jujutsu (jj), a Git-compatible distributed version control system designed for better usability and performance. It renders a visual representation of the repository's commit history as a directed acyclic graph (DAG), showing commits, branches, and changes over time.

Unlike traditional tools, Jujutsu uses an operation-based model where changes are recorded as immutable operations on a working copy, enabling features like automatic rebasing and concurrent work. The log displays revisions with details like author, date, description, and change counts. By default, it shows the main branch history with a graph view using ASCII art for edges.

Users can filter by revisions, limit output, or customize with templates. It's ideal for navigating complex histories, inspecting changes, and understanding repository state. Output supports color for readability and can pipe to pagers. Essential for jj workflows, it integrates seamlessly with other jj commands like jj diff or jj show.

Requires Jujutsu installation; not a core Linux utility. Revsets use jj syntax, not Git. Large repos may slow rendering.

jj log -r 'branch(main)' --limit 10
Shows last 10 commits on main branch with graph.

Powerful query language: roots(), children('rev'), draft(), @ for working copy.

Developed by Martin von Zweigbergk as part of Jujutsu (first release 0.1.0 in 2022). Evolved from hg-log influences, optimized for jj's concurrent operation model. Widely used in jj workflows since v0.5+ for improved UX over Git.
