Why build from a Thallo spec?
Written for AI agents
Every spec spells out layout, typography, motion, and responsive behavior — no coding required to write it.
Complete build spec
Each spec covers every page and interaction shown in its live demo.
New sites, regularly
New sites join the library on a regular schedule, all included with Pro.
Fully responsive
Every spec covers desktop, tablet, and phone — not just the screenshot.
Your stack, your code
The site builds straight into your own repo. Nothing rented, nothing locked in.
Any AI agent you trust
Specs are plain text, ready for the AI agent you already use.
