Rv: Non-invasive open source AI code review for any type of workflow (github.com)

The recently launched rv is a non-invasive, open-source AI code review tool designed for seamless integration into any workflow. Operating as a command-line interface (CLI), rv allows developers to review both their current code and that from past commits, branches, or pull requests. Adhering to the Unix philosophy, rv is minimalistic, comprising only about 1,500 lines of code, and is optimized for speed and cost, enabling code reviews in under 10 seconds at an average cost of just $0.002 using low-latency models such as Qwen3-32B. Significantly, rv empowers developers with full customization through its configuration file, supporting various language models (LLMs) and providers. Its straightforward Rust code enhances usability while promoting safe coding practices. As an open-source project under the GPL license, rv commits to a non-monetized model, meaning users won't face subscription fees or cloud credits. Exciting future features are on the roadmap, including enhanced context support for larger reviews, integration with Git hooks, and expanded documentation capabilities, positioning rv as a versatile tool in the evolving landscape of AI-assisted development.
