Cloudflare

The free tier provides basic CDN caching, DDoS protection, shared SSL certificates, and automatic HTTP/2 support. It also includes a limited set of firewall rules and analytics. For more advanced features like image optimization, load balancing, or custom SSL, you would need to upgrade to a paid plan, starting at $20 per month.

Cloudflare caches static content at its global edge network, reducing the distance between the visitor and the data. It also compresses files, optimizes image delivery, and routes traffic over the fastest available paths. These actions lower latency and decrease load times, especially for users far from your origin server.

Yes, Cloudflare works with virtually any web host or platform that allows you to change your domain's nameservers. After pointing your domain to Cloudflare's nameservers, the service sits in front of your existing server, handling DNS, caching, and security without requiring changes to your hosting environment.

The free plan limits you to shared SSL certificates, a modest number of firewall rules, and basic analytics. It does not include advanced performance tools like image resizing, mobile optimization, or priority support. For businesses needing these capabilities, a paid plan starting at $20 per month is required.

Cloudflare offers a free tier with essential CDN and security features, and a paid tier at $20 per month that adds advanced performance tools, more firewall rules, and dedicated support. The pricing is tiered, so you can start for free and upgrade only when you need the additional capabilities.
