Sher: The Free Alternative to ngrok and Vercel Preview URLs
You haven't heard of this CLI tool, but it solves localhost sharing better than the big names.
Sher: The Free Alternative to ngrok and Vercel Preview URLs
You haven't heard of Sher, but it solves a daily developer pain point better than the tools you're already paying for.
While ngrok charges for persistent URLs and Vercel requires GitHub repos for preview deployments, Sher generates instant preview URLs for local development projects with a simple command. It's freemium, works with Vite, Next.js, and Astro out of the box, and eliminates the friction of sharing local development previews.
The Problem It Actually Solves
Every vibecoding developer hits this: you're building something locally, want to show a teammate or client, and suddenly you're either:
- Pushing unfinished code to GitHub to get a Vercel preview
- Fighting with ngrok's free tier limitations
- Copying and pasting localhost screenshots like it's 2010
Sher just works. Run sher in your project directory and get a shareable URL immediately. No account setup, no tunnel configuration, no deployment pipeline.
Why It's Better Than the Alternatives
vs ngrok: No account required for basic usage, works with popular frameworks without configuration, and doesn't throttle connections on the free tier.
vs Vercel previews: No git commits required — share work-in-progress directly from your development server.
vs LocalTunnel: More reliable connections and better framework integration.
The Underrated Tool Pattern
Sher represents a category of tools that solve specific developer friction points without fanfare. No VC funding, no conference talks, just a CLI that eliminates a daily annoyance.
Sometimes the best tools are the ones that just work without making you think about them.
