How it works
From terminal to browser in seconds
incognito-dev automates every step of launching your local dev environment — from running your server to opening it in a clean browser session.
Detect Your Package Manager
Automatically detects whether you're using npm, yarn, pnpm, or bun — no config needed.
Run the Dev Command
Starts your dev server using your project's configured dev script (npm run dev, yarn dev, pnpm dev, or bun run dev).
Detect the Local URL
Watches your dev server's output and picks up the localhost URL the moment it appears — whatever port it lands on.
Launch in Private Mode
Opens your local server in Chrome Incognito — or a Brave / Edge private window with the --browser option.
