What is HTTPS?
HTTP over TLS — encrypted web traffic that prevents eavesdropping and tampering between the browser and server.
HTTPS encrypts the connection between browser and server using TLS (Transport Layer Security, formerly SSL). Modern browsers warn users on non-HTTPS sites, and Google uses HTTPS as a (minor) ranking signal. Free, automatic TLS certificates from Let's Encrypt and Cloudflare have made HTTPS the default — there's no reason to serve a public site over plain HTTP in 2026. InBuild published sites and exported projects (when hosted on Vercel/Netlify/Cloudflare) get HTTPS automatically.
