Sher: The Dev Preview Tool Everyone Needs

You haven't heard of Sher, but you need it. While everyone's building flashy AI agents and complex infrastructure, this unglamorous CLI tool solves a daily developer pain point that we've all just accepted: sharing local development previews.

The Preview URL Dance

Every developer knows the routine. You're working locally on a feature, need to show someone, so you either:

  • Push to GitHub and wait for Vercel to deploy
  • Create a temporary branch and deploy it
  • Set up ngrok and deal with random URLs
  • Take screenshots and explain what it "will look like"

It's friction that adds up to hours every week.

What Sher Does Differently

Sher is a simple command-line tool that generates instant preview URLs for local development projects. Works with Vite, Next.js, Astro, and other popular frameworks. Run sher in your project directory, get a shareable URL immediately.

No accounts, no complex setup, no wondering if your tunnel is still running. It just works.

Why It's Better Than Alternatives

Ngrok requires account setup and gives you random URLs that expire. Localtunnel is unreliable. Vercel preview deploys are overkill when you just want to show someone a quick change.

Sher fills the gap between "take a screenshot" and "deploy to production." It's the tool that should have existed years ago but nobody built because it's not sexy enough.

The Power of Boring Tools

Sometimes the best tools are the ones that just work without fanfare. Sher doesn't have AI, doesn't have a SaaS dashboard, doesn't promise to revolutionize your workflow. It just solves one specific problem really well.

This is infrastructure that every developer needs but few have heard of. While everyone focuses on the next big thing, tools like Sher handle the daily friction that actually slows us down.
