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

You haven't heard of Sher, but you should use it daily. While developers default to ngrok or deploy to Vercel for quick previews, Sher offers instant localhost sharing that's completely free and framework-aware.

The Problem Everyone Has

You're building a feature. Designer wants to see progress. Client needs a quick preview. Teammate found a bug but can't reproduce it locally. The solution is always the same dance: push to Git, wait for Vercel deployment, share the URL, repeat.

ngrok works but requires paid plans for custom domains and multiple tunnels. Vercel previews are great but create deployment overhead for work-in-progress code.

What Makes Sher Different

Sher understands development frameworks. Run sher in your Vite project, and it automatically detects your dev server and generates a shareable URL. Same for Next.js, Astro, or any localhost server.

No configuration. No accounts. No deployment pipeline. Just instant preview URLs that update in real-time as you code.

Why It's Underrated

Sher does one thing extremely well instead of trying to be a platform. It's the kind of unglamorous CLI tool that saves 10 minutes every time you need to share work-in-progress.

The lack of buzz is actually a feature — tools that solve daily friction don't need marketing hype. They spread through "hey, how did you do that?" conversations.

Try it next time you need to share localhost. Sometimes the most valuable tools are the boring ones that just work.
