A lightweight, self-contained web-based code review tool. Browse a project's source files, add inline annotations to specific lines, and have everything persisted to a REVIEW.md markdown file.

The tool was vibecoded as a simple way to review agentic coded files. The markdown file created by this tool can be fed back to your coding agent.

• File tree navigation — browse the project with expandable directories
• Inline annotations — click any line to add, edit, or delete review comments
• Syntax highlighting — powered by Chroma
• Git status integration — files and directories are color-coded by git status (modified, staged, untracked, etc.)
• Markdown storage — all annotations are saved to REVIEW.md with surrounding code context, making them easy to read and share without the tool
• Single binary — the web frontend is embedded in the Go binary; no external files or dependencies needed at runtime

Requires Go 1.24+.

go build -o review .

or

make

# Review the current directory on the default port (7070)
./review

# Review a specific directory on a custom port
./review -dir /path/to/project -port 8080

Then open http://localhost:7070 (or your chosen port) in a browser (should happen automatically).

The tool serves a three-panel web UI:

1. File tree (left) — project files with git status indicators and comment markers
2. Code viewer (center) — syntax-highlighted source with clickable lines
3. Comment sidebar (right) — list of annotations for the current file and an editor

Annotations are stored in memory and flushed to REVIEW.md in the project root on every change. The markdown file groups comments by file and includes a few lines of code context around each annotated line, so it remains useful on its own.

The tool exposes a JSON API for the frontend:
