Sher: The Preview URL Tool Your Dev Workflow Has Been Missing

You're deep in development on your Next.js app, need to show a client the progress, or test on mobile. The usual dance: deploy to Vercel, wait for build, send link, realize you need to make changes, repeat. Or fire up ngrok, deal with random URLs, remember to keep the terminal open.

Sher cuts through this friction with surgical precision.

What Makes Sher Different

While ngrok is the Swiss Army knife of tunneling, Sher is purpose-built for modern web frameworks. It understands Vite, Next.js, and Astro out of the box — no configuration, no wondering which port to expose.

Run sher in your project directory. Get an instant preview URL. That's it.

The tool clearly works (check their video demos), but it's flying completely under the radar with just 1 vote total on most discovery platforms. This is exactly the kind of focused, practical tool that makes vibecoding workflows smoother.

Why Preview URLs Matter

Local development has a sharing problem. Your localhost:3000 is useless to anyone not sitting at your machine. The existing solutions:

• Deploy previews: Slow, tied to git commits, overkill for quick checks
• ngrok: General-purpose tunneling, requires setup, random URLs
• Framework-specific solutions: Vercel's CLI is great but locked to their platform

Sher sits in the sweet spot: framework-aware, instant, and free.

The Vibecoding Appeal

This represents everything vibecoding is about — simple tools that remove development friction without adding complexity. No accounts, no configuration files, no vendor lock-in. Just point it at your project and get a shareable URL.

For a tool this practical to have such low visibility shows how much good stuff is hiding in plain sight. Sometimes the best solutions are the ones that do exactly one thing incredibly well.
