Sher: The Localhost Sharing Tool Everyone's Missing

You haven't heard of sher, but you should have. While everyone defaults to ngrok for sharing localhost previews, sher is purpose-built for the frameworks you're actually using.

The Daily Developer Pain

How many times this week did someone ask "can you just quickly look at this?" You're deep in a Vite dev server, they need to see the latest changes, and suddenly you're wrestling with ngrok tunnels or pushing half-finished work to a staging branch.

Sher solves this with one command: instant preview URLs that just work with Vite, Next.js, and Astro. No configuration, no tunnel setup, no "wait while I deploy this real quick."

Why It's Better Than ngrok

ngrok is general-purpose tunneling. sher is framework-aware sharing. It understands your dev server setup and generates URLs that preserve hot reloading and debugging context.

The difference: ngrok creates a tunnel to your port. sher creates a preview experience optimized for modern JavaScript frameworks. Your collaborator sees exactly what you see, with working HMR and proper asset loading.

The Underground Appeal

Sher has video demos, active maintenance, and solves a problem every developer has multiple times per day. Yet it's flying completely under the radar — just 1 vote on Product Hunt despite being genuinely useful.

That's underground gold: tools that work but haven't hit the hype cycle yet. While everyone's talking about AI agents, sher quietly solves localhost sharing better than alternatives that cost $5-20/month.

The freemium model is perfect — free for the quick "check this out" use case, paid tiers for teams that need it integrated into their workflow.

Next time someone needs to see your localhost, skip the ngrok dance. Try sher and watch their reaction when it just works.
