What they say it does

PR Preview is a free, open-source npm CLI that records a before/after video of your pull request. Ask Claude Code to record it — through the built-in MCP server it drives your app in a real Chrome window and captures the journey automatically — or run it by hand. Either way reviewers see the actual visual change, not just the diff. Runs locally; nothing is uploaded.
