About nertia

nertia is a website builder. The builder is free. Your site is a file you can download at any time, so nothing holds you here except liking it.

Start at nertia.ai. For the step by step, read Using nertia.

The idea

Most builders are built to keep you inside. The structure of your site lives in their editor, export is an afterthought, and the price creeps up once you can't leave.

nertia keeps the three parts of a site apart: the layout, the style and the words. Together they make a recipe, which is the whole site in one file. You can download it, hand it to someone else, or host it on your own domain.

AI helps with the polish. It does not own the site.

What we hold to

• Your site is a file. Download it whenever you like. Nothing is held back.
• Your words, your look. Describe what you need, or start from a style the community made, then edit it in the browser.
• AI is optional. Bring your own key, or buy coin as you go.

Pricing

Your first site on {slug}.nertia.ai is free on Zero-Point, for good. Particle and Wave add your own domain, social, code sites and AI. No card to start. No ads. We never sell your data.
