Sher: The Local Dev Preview Tool You Didn't Know You Needed

You haven't heard of Sher yet, but it solves a daily developer annoyance you didn't know had a name: sharing local development previews. One command generates an instant preview URL for your Vite, Next.js, or Astro project. No deployment, no port forwarding, no "can you VPN into our network" conversations with clients.

The Problem It Solves

Every developer has been here: you're working on a feature and need to show it to a teammate, client, or stakeholder. Your options suck:

• Deploy to Vercel/Netlify (overkill for quick previews)
• Walk them through port forwarding (awkward)
• Schedule a screen share (kills momentum)
• Create a GitHub repo just for sharing (extra overhead)

Sher eliminates this friction entirely. Run sher in your project directory, get a URL, share it. Done.

Why It's Better Than Alternatives

Ngrok exists but requires setup and has connection limits. Vercel previews are great but require git commits and deployment time. Sher works with your existing development server instantly.

The magic is in the simplicity — it just works with popular frameworks out of the box. No configuration, no accounts for the free tier, no complex routing rules.

When You'll Use It

• Quick client feedback sessions
• Cross-team collaboration
• Mobile testing on different devices
• Showing work-in-progress to stakeholders
• Getting feedback before committing to version control

It's one of those tools that becomes indispensable once you try it. The kind that changes your workflow permanently because it removes friction you didn't realize was slowing you down.

The Catch

Sher isn't revolutionary technology — it's good execution on a simple idea. The free tier has reasonable limits, and paid plans are affordable for teams. Works with all the frameworks you're already using.

Sometimes the best tools aren't the most innovative ones. They're the ones that solve annoying problems elegantly. Sher is exactly that — a friction-removing tool that just works.
