DemoBot.dev
Runs your branch and posts real UI screenshots as a comment on every pull request.
DemoBot installs as a GitHub App, detects your framework, and on every pull request it actually builds and runs the branch, then posts real screenshots of the changed views as an inline PR comment along with a plain-English summary of what changed. It's not AI-generated mockups, these are photographs of the app you actually run. Pricing is usage-based: Hobby is $10/month for 20 demos (first month free), Team is $50/month for 125 demos, and only the PR-open trigger is automatic, extra demos on the same PR are manually triggered to conserve credits.
What holds up
- +Screenshots are real, from your actual running branch, not AI-generated mockups.
- +Works across Next.js, Vite, Remix, Nuxt, SvelteKit, Astro, Expo, and more without custom config.
- +Posts an inline PR comment, so reviewers see the UI change without checking out the branch.
Mind the limits
- −Only the first demo per PR runs automatically — later demos need a manual trigger to save credits.
- −Hobby plan caps at 20 demos/month — active teams will likely need the $50/month Team tier.
