Sher: The Free ngrok Alternative You Haven't Heard Of

You haven't heard of sher, but you should have. It's the free, simple solution to a problem every developer faces daily: quickly sharing your local development work.

The Problem Everyone Has

You're working on a feature locally. Your designer wants to see it. Your client needs a quick preview. Your teammate is debugging something that only reproduces in your environment.

The options suck:

• Deploy to Vercel (overkill for a 30-second preview)
• Use ngrok (costs money for custom domains, rate limits)
• Create a GitHub repo and deploy (way too much friction)
• Screenshot/screen share (doesn't let them actually interact with it)

What Sher Does

One command: sher. You get an instant preview URL for whatever's running on localhost. Works with Vite, Next.js, Astro, and basically any local dev server.

No signup. No configuration. No rate limits. Just a shareable URL that lets people interact with your work in real-time.

The fact that it has video documentation and works across popular frameworks tells you the developer actually thought through real-world usage instead of just scratching their own itch.

Why It's Underrated

Sher does one thing well instead of trying to be a platform. While ngrok pivots into "secure tunnels for production" and Vercel builds a deployment empire, sher stays focused on the simple use case: instant local preview sharing.

Sometimes the best tools are the boring ones that solve daily pain points without fuss. You don't need secure tunnels or custom domains or analytics. You need to show someone your localhost:3000 without friction.

The Free Alternative to Paid Solutions

ngrok's paid plans start at $8/month for features most developers need occasionally. Vercel's preview deployments are great but require pushing to GitHub first. sher is free and instant.

It's the kind of tool you bookmark and forget about until you need it, then realize it saves you 10 minutes every time you use it.
