/dev/fast builds Review, an open-source desktop app for code review in the era of coding agents. The buyer decision is whether a team needs architecture-level understanding of a large diff and its agent trace, rather than another line-by-line reviewer or a summary bot.

## What it does

Review presents interactive visualizations, diffs, and agent trajectories in one review surface. The public demo describes sequence and database diagrams, chat with the authoring agent, and trace links that let a reviewer connect an implementation decision back to the change. The broader /dev/fast roadmap also names local trajectory storage, merge rules, code storage, and programmable CI ([Review homepage](https://dev.fast/); [/dev/fast about](https://dev.fast/about/)).
