Diffsmith

Diffsmith transforms your code review process for locally generated changes. Key capabilities include: • Inline comment anchoring on specific code lines • Direct hand-off of feedback to coding agents • Support for MCP for agent replies within the app • Watches local changes live for continuous review • Fully offline, native macOS application This application is designed to streamline the review of code produced by various coding agents. You can open any local Git repository, easily read uncommitted diffs, and pinpoint exact lines to leave comments without manual retyping. Your feedback can then be copied as a formatted prompt, ready to be pasted directly back to your coding agent. Diffsmith also supports a local MCP server, allowing your coding agent to read comments and reply within the application, eliminating the need for copy-pasting. The continuous re-diffing as files change means you can start reviewing before an agent finishes its work, enabling a more iterative and less overwhelming review experience. It's a fast, sandboxed, and properly integrated macOS application, ensuring a smooth and responsive user experience. Ideal for individual developers and small teams using coding agents who need an efficient, precise, and integrated way to review local code changes before they become pull requests. It supports a wide range of agents and offers lifetime access with a one-time purchase, ensuring privacy with its 100% offline operation.
