Sher: The Localhost Sharing Tool You Haven't Heard Of

You haven't heard of Sher, but you should have. It's the unglamorous CLI tool that solves one of the most frequent dev annoyances: sharing localhost previews.

The Daily Pain Point

You're building something locally. A teammate asks to see it. Your options suck:

• Push to GitHub, deploy to Vercel, send link (5 minutes)
• Set up ngrok, remember the command, share tunnel URL (2 minutes)
• Tell them to wait until you deploy it (annoying)

Sher makes this instant: sher in your project directory, get a preview URL immediately.

Why It's Better Than Alternatives

Vercel previews require git commits and actual deployments. Ngrok requires setup and paid plans for custom domains. Screen sharing is clunky for code review.

Sher works with Vite, Next.js, Astro, and other dev servers out of the box. It detects your framework, tunnels the right port, and gives you a clean URL that works anywhere.

The killer feature: it's designed for development workflows, not production. No account required, no credit card, no complex configuration.

Free and Simple

Sher is free with reasonable limits — perfect for the "quick, take a look at this" use case that happens multiple times per day in active development.

It's the kind of tool you discover, install once, and then use constantly without thinking about it. Like curl or jq — invisible infrastructure that just works.

Install it: npm install -g sher. Use it: sher in any project directory. Share the URL. That's it.
