Critique interactive visualizations, diffs, and agent traces, all from one interface.","body":"**TL;DR:** _Review is an open-source desktop app designed to give you confidence in your code. Critique interactive visualizations, diffs, and agent traces, all from one interface. It’s like Cursor, but purpose-built for code review._\n\n**Our Ask:** Try our app on your toughest code reviews; it is most illuminating for large, complicated changes. [Download the app](https://install.dev.fast/), [star the repo](https://github.com/devdotfast/review), \u0026amp; ask your questions on our [Discord](https://discord.gg/dev-fast)!\n\n**Demo Video:** \u003chttps://youtu.be/mDgxhzrFi2Y\u003e\n\n**The Problem:**\n\nNo one knows how much code we should be reading these days.\n\nIt feels tedious and old-fashioned to manually comb through thousands of lines of changes, and yet irresponsible to merge code you can’t confidently describe.\n\nWe’ve lost touch with how our own systems work.\n\nBuilding a company is a long game. Development is an iterative process. It takes accountability and code comprehension at every stage to build a great product that customers can count on ([ex 1](https://www.geoffreylitt.com/2026/07/02/understanding-is-the-new-bottleneck), [ex 2](https://margaretstorey.com/blog/2026/02/09/cognitive-debt/)).\n\n**Our Solution:**\n\nBefore AI, staff engineers understood massive software systems even when they didn’t have time to read all contributed code. They prioritized without sacrificing complexity by:\n\n\\- Scrutinizing RFCs and architecture diagrams\n\n\\- Skipping low-impact PRs\n\nReview treats you like a staff engineer. You can think of it as a ‘Cursor for code review.’ It helps you build programmatic, customizable RFCs from your PRs using coding agents.\n\nInstead of reviewing 1000+ line diffs you:\n\n1\\. Consult a variety of interactive diagrams built on our SDK:\n\n![uploaded image](/media/?type=post\u0026id=112248\u0026key=user_uploads/2724635/4db58f4d-cdcc-4825-966d-c92ffcfedeba)\n\n2\\.
