sher: The Localhost Sharing Tool Everyone Needs

You haven't heard of sher, but you need it.

It's the unglamorous CLI tool that solves an obvious problem elegantly: sharing your local development server with clients, teammates, or testers without the friction of ngrok tunnels or pushing to Vercel for every tiny change.

The Problem

You're working on a Vite app, Next.js project, or Astro site locally. A client wants to see progress, or you need feedback from a designer. Your options are:

1. ngrok — great tool, but requires setup, account management, and the free tier has limitations
2. Vercel preview URLs — requires committing code and waiting for deployment
3. Deploy to staging — overkill for quick feedback loops

All of these add friction to the natural development flow.

What sher Does

sher generates instant preview URLs for your local development projects. One command, and your localhost:3000 is available at a shareable URL. No configuration, no accounts, no deployment pipeline.

It works with all the frameworks vibecoding developers actually use: Vite, Next.js, Astro, and standard dev servers. The tool detects your setup automatically and handles the rest.

Why It's Better

Compared to ngrok: No account required, no download size bloat, no tunnel management. Just instant URLs.

Compared to Vercel previews: No git commits, no deployment wait time, no CI/CD overhead. Perfect for rapid iteration cycles.

Compared to manual staging deployments: No server management, no deployment scripts, no infrastructure complexity.

The Boring Tool That Saves Time

Sometimes the best tools are the boring ones that solve obvious problems. sher saves maybe 10 minutes per day, but those minutes compound. Client demos become spontaneous instead of planned events. Design feedback happens in real-time instead of async cycles.

It's freemium with a generous free tier — more than enough for individual developers and small teams.

For vibecoding developers who value speed and simplicity over complex infrastructure, sher is the kind of utility that quietly makes everything smoother.

Try sher — it's the localhost sharing tool you didn't know you were missing.
