Sher: The Localhost Sharing Tool Nobody Talks About

You haven't heard of sher, but it might be the most useful developer tool you're not using.

The Problem Everyone Just Accepts

You're working on a local project and need to show someone a quick preview. Your options suck: spin up ngrok and deal with random URLs, push to GitHub and wait for Vercel to build, or try to explain what it would look like over Slack.

Most developers just accept this friction. "It's only a few minutes," we tell ourselves, then waste hours over the course of a project dealing with preview logistics.

What Sher Does Differently

sher generates instant preview URLs for local development projects with zero configuration. It works with Vite, Next.js, and Astro out of the box — the frameworks you're actually using for modern web development.

While ngrok is a generic tunneling tool and Vercel previews require deployment, sher is purpose-built for the dev preview use case. One command gets you a shareable URL that just works.

Why It's Underrated

With video documentation and a freemium model, sher has all the hallmarks of a tool that should be everywhere. Instead, it has minimal traction because it solves a problem people think they've already solved.

But there's a difference between "solved" and "solved elegantly." ngrok works, but it's overkill for dev previews. Vercel deployments work, but they're slow and require git commits. sher is the right tool for the specific job.

Sometimes the most valuable tools are the ones that make annoying tasks disappear entirely. You won't realize how much friction you were accepting until you use something that eliminates it completely.
