DemoBot

Code review shows you the diff, and the diff can't tell you what the product actually looks like. To see a UI change today you check out the branch and run it, or click around a preview deploy hunting for what moved. Most reviewers skip that, so UI changes get approved sight unseen. DemoBot fixes this. Install the GitHub App, open a pull request, and DemoBot spins up your app from the branch, reads the diff, captures real screenshots of the affected views, and posts them as an inline PR comment with a summary of what changed. Real screenshots of your running app, never generated mockups. Works with Next.js, Vite, Remix, Nuxt, SvelteKit, Astro, and anything else that builds and runs. Framework detection is automatic. Apps behind a login just need test credentials. First month of Hobby is free, no card required.
