In app/root.tsx, add the tag inside <body>, after <Scripts />:
<body>
<Outlet />
<ScrollRestoration />
<Scripts />
<script async src="https://sendshot.dev/widget.js" data-key="YOUR_PROJECT_KEY" />
</body>
Replace YOUR_PROJECT_KEY with the key from Project → Settings → Installation in your Sendshot dashboard.
Check it works
Open your site. The feedback button appears in the bottom-right corner after the page has loaded. Press Cmd/Ctrl + Shift + F to open it from the keyboard, send a test report, and it shows up in your dashboard.
No button? Make sure the domain you're on is listed in the project's allowed domains.
