Sher: The Local Preview Tool You Didn't Know You Needed

You haven't heard of Sher, but it solves one of those mundane developer problems that happens multiple times per day: quickly sharing local development previews.

Sure, ngrok exists. But Sher is built specifically for modern frameworks like Vite, Next.js, and Astro. One command generates an instant preview URL for your local development server. No configuration, no tunnel setup, no remembering random port numbers.

The Problem It Actually Solves

"Can you just take a look at this?" is probably the most common request in development workflows. But sharing local work means either pushing to a branch and deploying to Vercel, screensharing a call, or walking someone through your localhost setup.

Sher eliminates that friction. Run sher in your project directory, get a public URL immediately. Your local development server becomes instantly shareable.

Why It's Underrated

Most developers don't think about preview sharing as a "tool" — it's just part of the workflow friction they accept. But removing small, frequent annoyances often provides more daily value than complex tooling you use occasionally.

The freemium model makes it accessible for individual developers and small teams. They've even created video documentation, recognizing that sometimes the simplest tools need the clearest explanation.

The Comparison

Compared to ngrok (the standard tunnel solution), Sher is optimized for development previews rather than general tunneling. It understands modern framework conventions and handles the preview use case specifically.

Compared to deploying preview branches, Sher gives you the instant feedback loop of local development with the shareability of deployed previews.

Try it: sher.sh

Sometimes the most valuable tools are the ones that solve small problems elegantly. In vibecoding workflows where speed matters, eliminating the "let me push this and deploy it so you can see" cycle is exactly the kind of optimization that compounds over time.
