Dev Tab Organizer

About

Instantly label localhost tabs by service name — ⚡ 3000 → React, ⚡ 8080 → Spring Boot. Zero config.

Dev Tab Organizer automatically rewrites your localhost tab titles to include the port number and service name, so you can identify each local service at a glance.

✅ Zero configuration — works immediately on install
✅ Ships with 10+ default port mappings (React, Vite, Angular, Django, Flask, and more)
✅ Preserves the original page title as a suffix
✅ Handles SPA client-side navigation without flickering or double-prefixes
✅ Minimal permissions — only accesses localhost and 127.0.0.1 tabs

HOW IT WORKS
When you navigate to localhost:3000, the tab title changes from "My App" to "⚡ 3000 — My App" automatically. No setup, no configuration, no accounts.

DEFAULT PORT MAP
3000 → React | 5173 → Vite | 4200 → Angular | 4000 → Phoenix | 8000 → Django
5000 → Flask | 8080 → Spring Boot | 8888 → Jupyter | 1234 → Parcel | 9000 → Webpack

PRIVACY
This extension stores no personal data. Custom port name mappings are saved locally in Chrome's built-in sync storage and never transmitted to any external server.
