Selenite Vercel is not just another hosting platform—it’s a highly optimized ecosystem for Crystal apps, featuring:
- Built-in Selenite plugin for seamless integration
- Edge Functions for dynamic logic at the CDN level
- GitHub Actions & Vercel CLI for smooth workflows
💡 Pro Tip: Companies using Selenite Vercel report 2x faster deployments and 30% lower bounce rates due to speed optimizations.
2. Step-by-Step Selenite Vercel Setup & Deployment
2.1 Prerequisites
Before deploying:
- A Crystal app (built with Lucky, Amber, or raw Crystal)
- Vercel account (Free tier available)
- GitHub/GitLab repo for automatic deployments
2.2 Installing the Selenite Vercel Plugin
bash
