What happened?
Running impeccable detect against a live URL causes a visible browser-like or black pop-up window to appear.
For example:
impeccable detect https://example.com
The window may appear briefly while the page is being scanned. Since URL detection is expected to use a headless browser, no browser or additional window should be visible.
Steps to reproduce
-
Open a terminal.
-
Run:
impeccable detect https://example.com
-
Observe that a browser-like or black pop-up window appears while the command is running.
Expected behavior
The live page should be scanned entirely in headless mode, without opening or briefly displaying any browser, console, or black pop-up window.
Provider & environment
- Provider (Cursor / Claude Code / Gemini CLI / Codex / Copilot / Kiro / OpenCode): Any
- Provider version: Any
- OS: Windows 11 25H2
- Node.js version: v24.18.0
- Impeccable version: 3.2.1
Additional context
Command used:
impeccable detect https://example.com
The scan otherwise appears to run, but a visible browser-like or black window is displayed during the process.
Screenshots or a screen recording can be added here if needed.
