The Local Preview Tool Everyone Needs But No One Talks About

You're building something locally. You want to show it to someone. You either:

1. Deploy to Vercel for a quick preview (overkill)
2. Set up ngrok tunneling (friction)
3. Push to GitHub and wait for deployment (slow)
4. Take screenshots (inadequate)

Sher eliminates this daily developer pain.

What It Does

One command generates an instant preview URL for your local development server. Works with Vite, Next.js, Astro, and other popular frameworks. No configuration, no account setup, no tunnel management.

npx sher
# Outputs: https://preview.sher.sh/abc123

That URL points to your running local server. Share it immediately.

Why This Matters

Sharing local development previews is a boring problem that everyone just accepts as friction. But it happens multiple times per day:

• Showing progress to clients
• Getting feedback on features
• Testing on different devices
• Collaborating with remote team members

Sher turns a 5-minute process into a 10-second command.

Better Than Alternatives

Unlike ngrok, you don't manage tunnels or remember URLs. Unlike Vercel previews, you don't need git commits or deployment cycles. Unlike screenshots, stakeholders interact with the actual application.

It's freemium, actively maintained, and does one thing exceptionally well. Sometimes the best tools are the boring ones that save time every single day.

Try Sher — the preview tool that should be in every developer's toolkit.
