sher: The localhost Preview Tool You Haven't Heard Of

You haven't heard of sher, but it might save you 10 minutes every day.

It's a CLI tool that generates instant preview URLs for local development projects. Works with Vite, Next.js, Astro, and other modern frameworks. The difference? It's purpose-built for the vibecoding workflow.

Why Not Just Use ngrok?

ngrok is the standard solution, and Vercel preview deployments are great for production previews. But both have friction for the daily "hey, check this out" workflow:

• ngrok requires setup and doesn't integrate cleanly with modern dev servers
• Vercel previews require pushing to git and waiting for builds
• Both are overkill when you just want to show a client your localhost

sher is designed specifically for the modern frontend development workflow. One command gives you a shareable URL of whatever's running on your local dev server.

The Unglamorous Tool Problem

sher has barely any visibility (only 1 vote in our database), but it solves a problem every developer faces multiple times per week. These are the best kinds of tools — the ones that eliminate small daily friction.

While everyone debates which AI model is better, tools like sher quietly make development more pleasant. No fancy marketing, no buzzwords, just a better way to share localhost previews.

Try It

It's freemium, so you can test the workflow without commitment. If you're constantly sharing work-in-progress with teammates or clients, sher might become one of those tools you forget you lived without.

Sometimes the best tools are the ones nobody talks about.
