Sher: The Local Development Preview Tool You Haven't Heard Of (But Should Use Daily)

You haven't heard of Sher, but you've definitely felt the pain it solves. Every time you need to show a client your work-in-progress, share a bug reproduction with your team, or test your local build on a different device, you face the same friction: getting localhost accessible from the outside world.

The Problem Everyone Has

Most developers reach for ngrok, but it's overkill for simple preview sharing. You want to run sher start and get a URL you can text someone. That's it. No tunneling complexity, no account setup for basic use, no wondering if the connection will drop during your demo.

Sher is built specifically for this workflow. It integrates with Vite, Next.js, Astro, and other modern frameworks, automatically detecting your dev server and generating shareable URLs.

Why It's Better Than Alternatives

Unlike generic tunneling tools, Sher understands modern development workflows. It knows your framework's default ports, handles hot reload properly, and doesn't interfere with your existing dev setup.

The freemium model means you can use it immediately without commitment. Paid tiers add custom domains and analytics, but the core functionality works without payment or account creation.

Compared to Vercel Preview Deployments

Vercel previews are great for CI/CD, but overkill when you just want to show someone what you're working on right now. Sher gives you instant sharing for active development, not polished deployment previews.

You're not committing code, waiting for builds, or managing preview environments. You're sharing your actual dev server with a publicly accessible URL.

Why You Should Try It

Sher saves 10 minutes every time you need to share localhost. Over a month, that's hours of friction removed from your development workflow. It's the kind of unglamorous utility that improves daily quality of life without fanfare.

The fact that it has minimal visibility despite solving a universal problem makes it a perfect underground pick. Check out sher.sh and see if it fits your preview sharing workflow.
