The Local Preview Tool Everyone's Overlooking
Sher generates instant preview URLs for localhost projects — solving the daily developer pain of sharing work without deploying.
The Local Preview Tool Everyone's Overlooking
You haven't heard of Sher yet, but you should have. With only 1 vote on Product Hunt, it's flying completely under the radar while solving a problem every developer faces multiple times per week.
The problem: You're working on a feature locally. Your client wants to see it. Your teammate needs to review the interaction. Your designer wants to test the flow.
Your options suck:
- Deploy to Vercel (overkill for a quick preview)
- Push to GitHub and set up a preview branch (slow)
- Screen share or record a video (static, no interaction)
- Email screenshots (we're not animals)
What Sher Actually Does
Sher generates instant, shareable URLs for your localhost development servers. Works seamlessly with Vite, Next.js, Astro, and basically any local dev setup.
npx sher dev
Boom. You get a public URL that anyone can visit to see your local project running live. They can click around, test functionality, see real interactions.
Why This Matters More Than You Think
This isn't just convenience — it changes how you work with clients and teammates. Instead of async feedback loops with screenshots, you get real-time collaboration on actual functionality.
I've seen developers spend more time deploying preview versions than building features. Sher eliminates that entire category of friction.
The Competition Problem
Paid alternatives like ngrok exist, but they're overkill for simple previews and require account setup. Vercel's preview deployments are great but slow for rapid iteration.
Sher hits the sweet spot: instant, no-config, works with your existing setup. The freemium model means you can try it without friction.
The tool has both video and image demos, showing the creators understand the use case deeply. It's polished despite being unknown.
Try it: sher.sh
Sometimes the best tools are the ones that solve unglamorous problems really well. This is one of them.
