sher: The Localhost Sharing Tool Everyone Should Use Daily

You haven't heard of sher, but you should be using it every day. It's the localhost sharing tool that actually works the way you think it should.

Run sher in any local development project—Vite, Next.js, Astro, whatever—and get an instant shareable preview URL. Zero configuration, zero setup, zero vendor accounts required.

Why This Matters

Every developer faces this constantly: you're working locally and need to show someone what you're building. The options are terrible:

• ngrok requires account setup, complex configuration, and the free tier is limited
• Vercel preview deployments lock you into their platform and require Git commits
• Manual deployment breaks your flow and takes forever

sher solves this with the simplicity it should have always had. One command, instant URL, works with any framework.

Better Than the Incumbents

ngrok became the standard through early adoption, but it's overly complex for the common use case. Most developers just want to share a local build quickly, not set up permanent tunneling infrastructure.

Vercel's preview deployments are convenient if you're already in their ecosystem, but they force you to commit code and wait for builds. sher shares your actual local development server instantly.

The fact that sher is free and framework-agnostic makes it the obvious choice for this workflow. It's the kind of unglamorous utility that saves 10 minutes every day but gets overlooked because it's not shiny.

The Universal Developer Pain Point

This is exactly the type of tool that should be built-in to development environments but isn't. Every framework has hot reloading, but none have built-in sharing. sher fills that gap perfectly.

It's production-ready, actively maintained, and solves a problem every developer has multiple times per week. The kind of tool that becomes indispensable once you start using it.
