Stage

Stage is a code review tool that reorganizes local git changes and pull requests into logical, ordered "chapters" so engineers can review and merge changes far faster — a workflow built for teams shipping large volumes of AI-generated code. Stage ships an open-source (MIT) command-line tool, "stagereview", that runs entirely on the developer's machine and works with any AI coding agent (Claude Code, Cursor, Codex, Gemini, opencode): it diffs the current branch or a GitHub PR, clusters the hunks into narrated chapters with a prologue, and opens them in a local browser SPA for review. The full hosted Stage experience lives at stagereview.app. Stage is a Y Combinator (Spring 2026) company founded by Charles Pan and Dean Stratakos.

Stage is profiled on the APIs.io network. Tagged areas include Company, Code Review, Developer Tools, CLI, and AI Coding Agents.

Stage’s developer surface includes documentation, engineering blog, support, code examples, CLI, and 7 more developer resources.
