Sher: The Localhost Sharing Tool You Need

You haven't heard of Sher, but you need it.

Every developer faces the same problem: you're building locally with Vite, Next.js, or Astro, and you need to share a preview. Your options suck:

• ngrok works but randomly fails and has confusing URLs
• Vercel previews require commits and GitHub repos
• Heroku review apps take forever to spin up
• Sending screenshots feels like 2010

Sher solves this with one command that generates instant preview URLs for any local dev server. No configuration, no commits, no waiting.

Why It's Underrated

Sher has minimal votes despite solving a daily developer pain point. It's the kind of unglamorous utility that's easy to overlook but becomes essential once you try it.

The reliability advantage over ngrok is huge — Sher's infrastructure seems more stable, and the generated URLs are cleaner. The setup is simpler than Vercel previews since you don't need to commit unfinished work just to share a preview.

How It Compares

Versus paid alternatives:

• ngrok Pro ($8/month): Sher's freemium tier handles most use cases
• Vercel Pro ($20/month): Sher doesn't require repository setup
• Custom tunnel solutions: Sher just works without infrastructure management

The freemium model means you can use it immediately without billing setup. For solo developers and small teams, this removes a major friction point.

Try It

Install with npm install -g sher-cli, then run sher in any local project directory. You'll get an instant preview URL that works reliably.

It's the kind of tool that improves daily development workflow without fanfare. The underground builders excel at these practical utilities while everyone else chases shinier problems.
