Codebuff

Codebuff is a command-line tool (CLI) that deeply understands your project’s codebase, structural dependencies, and style. You install it globally (e.g. via npm), then interact with it by giving natural-language instructions in the terminal. It can read, modify, and refactor files, run tests or install packages, produce edits based on project context, persist knowledge between sessions, and perform surgical changes while respecting existing architecture. It emphasizes speed, minimal setup, and workflow integration.

Codebuff gives you power to modify and maintain your codebase via natural language *without leaving the terminal*. Its context awareness, ability to operate over file boundaries, run tests & commands, and remember previous interactions make it more than just a code suggestion tool — it acts more like a remote engineer working with your project. This can speed up workflows dramatically while maintaining code quality.

• Natural-language instructions from the terminal to modify codebase
• Full project indexing in ~2 seconds to understand structure, dependencies & patterns
• Ability to run terminal commands (e.g. install packages, run tests, check type errors) as needed
• Surgical edits: precise code changes that respect existing style & architecture
• Persistent project knowledge (knowledge files) to remember prior usage/context across sessions
• Zero or minimal setup beyond installing CLI; works with any tech stack
• Handles error detection and auto-fixing (tests, type errors etc.)
• Competitor benchmarking, including comparisons to tools like Cursor, GitHub Copilot etc.
