Sher: The Localhost Sharing Tool Nobody Talks About

You haven't heard of Sher because it does one thing well without trying to be a platform: it generates instant preview URLs for local dev projects with a single CLI command.

The Daily Pain Point

Every developer hits this multiple times per week: you need to share a local preview with a client, teammate, or stakeholder. Your options are usually:

• ngrok: Great tool, but the free tier is limited and paid plans add up
• Vercel preview URLs: Requires pushing to GitHub and triggering a build
• Other tunneling services: Complex setup or expensive pricing

Most of the time, you just want to run something localhost:3000 and get a shareable URL. That's exactly what Sher does.

Why It's Better

Sher works out of the box with popular dev frameworks (Vite, Next.js, Astro) and requires zero configuration. Install it, run sher, and get an instant preview URL. No accounts, no tokens, no setup complexity.

It's free for the use cases that matter most: quick previews and feedback loops during development. The focus on developer experience over monetization shows in the implementation.

The Underrated Tool Category

Sher represents a category of tools that gets overlooked because it's not venture-scalable: quality execution on daily developer friction. It's the kind of tool you install once and use hundreds of times without thinking about it.

While everyone chases AI agents and revolutionary platforms, tools like Sher solve the 10-minute problems that actually slow down development. Unglamorous but essential.

Try it: sher.sh

Sometimes the best tools are the ones that just work.
