Features
- Exact spot. Your UI feedback points to the exact file, line and column in your source code, so your agent doesn't have to search for it.
- Any Vite framework. React, Vue, Svelte, Solid, Astro, and so on.
- Zero imports. Nothing to import in your app code.
- Production stays clean. Spotnote runs only in
vite dev, and in staging builds you turn it on for. - Everything is local. No account, no cloud.
Requirements
- Vite 5 or later
- Node 22 or later
Install
npm install -D spotnote
Usage
// vite.config.ts
import spotnote from "spotnote";
export default defineConfig({
plugins: [react(), spotnote()],
});
Start your dev server and click the launcher in the bottom-left corner. Click an element, type what should change and press Enter. The prompt is on your clipboard: paste it into Claude Code, Cursor, Codex or any chat.
Output
The prompt Spotnote copies for a note, ready to paste into your agent:

Webhook
Send each note to a URL of yours as it's written: to post it to your team's chat or issue tracker, without the copy and paste.
spotnote({ build: ["staging"], webhook: "https://feedback.example.com/spotnote" })
build: ["staging"] keeps Spotnote in vite build --mode staging, for reviewers on a staging deploy (see Staging Builds). Each note arrives as JSON, with its text, page, file and line, commit, and prompt. Add screenshot: true to send a screenshot of the note's elements with it. See Webhook.

On a staging build with a webhook: press Enter, and the note lands in your team's chat, with its file and line, and a screenshot.
