EnvTunnel is a free, offline-ready desktop tool that scans running local dev servers and instantly generates QR codes, allowing you to open localhost on any device in your network with just a single scan.
Why it's noteworthy
EnvTunnel's primary strength lies in its local-first, offline-ready design, requiring no accounts or internet connection. It automatically scans over 16 common dev ports every 3 seconds, detecting frameworks like Vite, Next.js, Angular, Django, and Flask, and instantly generates a large QR code for easy access from your phone or tablet. Features like toast notifications, live reload indicators, and custom port/path configurations make the development workflow much smoother.
Who it's for
EnvTunnel is ideal for frontend and full-stack developers looking to test websites or APIs on real mobile devices. Designers can also use it to preview work across multiple screens within their local network. If you are tired of manually typing IP addresses like 192.168.x.x:3000 on your phone, EnvTunnel is the automation solution you need.
Quick comparison
While services like Ngrok or LocalTunnel.me require tunneling your local server to the cloud, EnvTunnel operates fully offline and locally, making it perfect for internal testing without an internet connection. Compared to manually configuring access or searching for IP addresses within the network, EnvTunnel automates everything, saving you significant time and eliminating tedious typing on mobile devices.
How to get started
EnvTunnel is currently available as a Windows application. To get started, simply visit the project's GitHub page to download and install it. Once installed, the app runs quietly in the system tray, automatically detecting active dev servers and serving QR codes whenever they go live.
