Sher: Instant Preview URLs for Your Local Dev Server

You haven't heard of sher, but you've definitely felt the pain it solves.

You're deep in development on a new feature. Your PM wants to see progress. Your client needs a quick demo. Your teammate needs to test the integration. But your work only exists on localhost:3000.

The usual options suck:

• Deploy to Vercel Preview = overkill for a 30-second check
• Push to GitHub and wait for CI = breaks your flow
• ngrok = requires account setup and remembering syntax
• Screen sharing = kills productivity

What sher Does Differently

sher generates instant preview URLs for local development with zero setup. It's specifically built for modern dev workflows with native support for Vite, Next.js, Astro, and other popular frameworks.

The magic is in the simplicity:

npx sher
# Automatically detects your framework and generates shareable URL
# Works with your existing dev server, no configuration needed

Unlike ngrok or similar tools that treat your local server as a generic web service, sher understands modern development patterns. It knows how to handle hot module replacement, handles framework-specific routing correctly, and doesn't break your development workflow.

Why It's Underrated

sher has minimal community traction because it's not a flashy AI demo or revolutionary new framework. It's just unglamorous infrastructure that saves you 10 minutes every single day.

But this is exactly the kind of tooling that busy developers need. While everyone's building the next AI coding assistant, sher quietly solves a universal pain point that every web developer hits multiple times per week.

The freemium pricing makes it accessible for solo developers and small teams who can't justify ngrok's enterprise pricing for occasional use.

Sometimes the best tools are the ones that get out of your way and just work.
