sher: The Localhost Sharing Tool You Didn't Know You Needed

You haven't heard of sher, but you'll use it multiple times per week once you discover it.

The Daily Developer Pain Point

Every developer faces this: you're working on a local project and need to quickly share a preview with a colleague, client, or stakeholder. The typical flow involves either deploying to Vercel, pushing to GitHub for a preview deployment, or wrestling with ngrok's randomly generated URLs.

sher eliminates this friction entirely. One command generates an instant preview URL for your local development server. No deployment, no git commits, no tunnel configuration.

Why It's Better Than the Alternatives

Unlike ngrok's generic tunneling approach, sher understands modern development frameworks. It works seamlessly with Vite, Next.js, Astro, and other popular dev servers out of the box. No port mapping, no configuration files — just run sher and get a shareable URL.

Compared to Vercel's preview URLs, sher doesn't require pushing code or triggering deployments. Your local changes are immediately shareable, perfect for rapid iteration cycles and quick feedback loops.

The Best Kind of Underground Pick

This represents the best category of underground tool: unglamorous, specific to real daily workflow friction, and clearly built by someone who uses their own tool. While the AI development community debates the future of coding, sher quietly solves a problem every developer encounters multiple times per week.

The freemium model and clean CLI interface suggest this is built for developers by developers — not a venture-backed platform trying to capture market share.

If you're building with AI tools and shipping fast, localhost sharing becomes even more critical. You're prototyping quickly, getting feedback frequently, and iterating rapidly. sher removes one more piece of friction from that workflow.

Try sher the next time you need to share a local dev preview. It's one of those tools you'll wonder how you lived without.
