A fast terminal UI for reviewing Git diffs and GitHub pull requests.

LazyDiff is for the code-review loop: jump through changed files, inspect hunks, search the diff, browse semantic changes, and keep your focus in the terminal.

Alpha: LazyDiff is currently intended for early adopters and dogfooding. Expect UI and workflow changes between alpha releases.

• Review worktree changes, staged changes, commits, refs, patch files, and stdin diffs.
• Browse pull requests from a terminal-first review queue.
• Open PR descriptions and changed files side by side.
• See semantic code changes powered by sem-core.
• Search within diffs and jump directly to matching files or hunks.
• Switch between unified and split diff views.
• Persist lightweight review state locally.
• Login, logout, and update from the CLI.

Install the latest release:

curl -fsSL https://raw.githubusercontent.com/Ataraxy-Labs/lazydiff/main/install | sh

Install a specific version:

curl -fsSL https://raw.githubusercontent.com/Ataraxy-Labs/lazydiff/main/install | sh -s -- --version v0.1.0-alpha.5

Verify the install:

lazydiff --version

cargo install --git https://github.com/Ataraxy-Labs/lazydiff

Open LazyDiff in a Git repository:

lazydiff

Review local changes directly:

lazydiff diff                    # worktree changes vs HEAD
lazydiff diff --staged           # staged changes
lazydiff diff origin/main        # current branch vs a base ref
lazydiff show HEAD~1             # a commit
lazydiff patch path/to/file.diff # a patch file
git diff --no-color | lazydiff pager

GitHub PR review uses device login:

lazydiff login
lazydiff logout

The GitHub device login needs an OAuth app client ID. Configure it locally:

# ~/.config/lazydiff/config.toml
github_client_id = "your-github-oauth-client-id"

Update LazyDiff from GitHub Releases:

lazydiff update

git clone https://github.com/Ataraxy-Labs/lazydiff.git
cd lazydiff
cargo run

Fast local TUI loop:

cargo build --profile dev-fast
scripts/dev-watch-tui.sh

Quality checks:

cargo fmt --check
cargo clippy --all-targets
cargo test

Release artifacts are published as GitHub Release archives for Linux, macOS, and Windows, with .sha256 checksums.

Release builds currently include a focused semantic grammar set — TypeScript/TSX, JavaScript/JSX, Python, Go, Rust, and Java — to keep binaries small. Other languages still fall back to normal textual diff review.

Issues and pull requests are welcome. See CONTRIBUTING.md for local development notes.
