sher: The Dev Preview Tool You Haven't Heard Of

You haven't heard of sher, but you should have. It's a command-line tool that generates instant preview URLs for your local development projects, working seamlessly with Vite, Next.js, and Astro.

The Problem It Solves

Every developer faces this daily: you're working locally and need to share a preview. Your options are ngrok (which is overkill and expensive for simple previews), deploying to Vercel (which requires git commits and wait time), or asking someone to look over your shoulder.

sher fills the gap between local development and full deployment. Run one command, get a shareable URL. No configuration, no accounts, no friction.

Why It's Better Than Alternatives

ngrok dominates the tunneling space but it's designed for production debugging and webhooks. sher is purpose-built for dev previews with a freemium model that makes sense for individual developers.

Vercel owns preview deployments but requires pushing to git and waiting for builds. sher shares what's running locally right now.

The tool is unglamorous but essential — the kind of utility that saves you 10 minutes every single day. Despite having minimal visibility (only 1 vote on Product Hunt), it has video demos and clearly solves a genuine pain point.

Built for the Vibe Workflow

For teams building with AI tools like Claude Code or Cursor, sher integrates naturally into the rapid iteration cycle. You're already working in the terminal, already iterating quickly on local builds. Adding sher share to your workflow is frictionless.

It's exactly the kind of tool that vibecoding developers discover through word-of-mouth rather than marketing campaigns. Simple, focused, and genuinely useful.
