Underground Pick: sher

You haven't heard of sher, but you've definitely felt the pain it solves. How many times today did you need to share a local development preview with a teammate or client?

For most developers, it's the same frustrating workflow: push to a branch, deploy to Vercel, wait for build, copy preview URL. Or fumble with ngrok configuration. Or just say "I'll show you on my screen."

The Problem It Actually Solves

sher generates instant preview URLs for local development projects with zero configuration. It works with Vite, Next.js, Astro — basically any framework running on localhost. One command, instant shareable URL.

This isn't revolutionary technology. It's just solving the "10 times a day" problem that everyone has but nobody talks about. The boring stuff that wastes 5 minutes here, 10 minutes there, until you realize you've spent an hour of your day on preview URL logistics.

Why It's Underrated

Because it's freemium and has video demos, sher feels more legitimate than typical developer tool side projects. But it has minimal votes on product hunt and almost no social media buzz.

Meanwhile, ngrok costs $8-20/month for teams and requires configuration. Vercel preview deployments are free but slow and create deployment noise. sher just works instantly.

The Comparison That Matters

This is exactly the kind of boring-but-essential tool that productive developers quietly adopt. It doesn't use AI, doesn't have a fancy landing page, doesn't promise to revolutionize development workflows.

It just solves a universal developer pain point with zero friction. Sometimes the best tools are the ones that get out of your way completely.

If you share localhost previews more than twice a week, try sher. It's the kind of tool you'll forget you're using until you try to work without it.
