valID

Real-time CSS selector validator and DOM monitor. Track IDs, classes, and attributes instantly.

valID is a lightweight, powerful developer tool designed to monitor DOM elements in real-time. Whether you are a frontend developer debugging a UI, a QA engineer tracking element visibility, or an automation engineer validating selectors, valID gives you instant visual feedback without cluttering your console. Key Features: ● Instant Validation: Add any CSS selector (ID, Class, Attributes, or Complex Selectors) and see immediately if it exists on the page. Visual Status Indicators: 🟢 Green: Element found. 🔴 Red: Element missing. ⚪ Gray: Pending check. ● Persistent Monitoring: Save your important selectors. valID remembers them and checks their status whenever you return to that URL. ● Smart URL Cleaning: Automatically strips dynamic query parameters (like session IDs or tracking codes) to ensure your monitors don't break when links change. ● Draggable Floating Widget: A clean, non-intrusive overlay that floats on top of your page. Move it anywhere to keep your workspace clear. ● One-Click Navigation: Click any monitored tile to instantly open the target URL in a new tab. Who is this for? ● Developers: Verify that dynamic elements (React/Vue/Angular) are mounting correctly. ● QA Engineers: Quickly check for the presence of critical buttons or forms during manual testing. ● Scraper/Automation Maintainers: Validate selectors before using them in scripts. Privacy: valID runs entirely locally on your machine. No data is sent to external servers.
