How to redesign your website from its URL with AI: 7 tools compared

Paste your current address into Repaint, Revamp, Macaly, Shuffle, Readdy, 10Web or iter0 and each one reads the live site and builds a new version beside it. They differ in what they keep, where the new site lives and whether you can take the code away. Repaint, Revamp and Macaly host the result. Shuffle and Revamp's Studio plan hand you code. 10Web gives you WordPress. iter0 takes your site for the content and a second site for the look.

AI landing page builders for a startup launch: Framer, Unbounce, Carrd, Lovable, v0 and iter0 compared

Pick by who will change the page after launch. Framer suits a designer or marketer. Unbounce suits a team running paid ads that wants to test variants. Carrd is the cheapest way to get a one-page site on your own domain, at $19 a year. Lovable and v0 suit a developer who wants the page in the same code as the product. iter0 asks about your buyer and offer first, then builds a page you can download.

Durable alternatives: 9 website builders compared on cost, bookings and export

Durable has no site download: its help centre exports your customer list as a CSV, and the pages you rebuild by hand. So choose the next builder by what you would miss and by what you can take with you next time. Wix and B12 are the closest swaps for Durable's bundle of website, customer list and bookings. Squarespace, Framer and Webflow are better editors. Hostinger and 10Web are the cheapest hosted options. Lovable builds web apps, and iter0 builds a launch page you download as HTML, with no lock-in. Below: what a year on your own domain costs on each, what each lets you export, and how to switch.

Ecommerce website redesign: what to keep and what to change

Change the layout and the look. Keep your product addresses, your product text and your checkout until the new design settles. Record your numbers before you start, redirect every address that moves, and compare each group of pages with its baseline after launch.

Framer vs Lovable vs v0 for a startup launch page

Choose by who edits the page next. If a marketer or designer will, use Framer: a hosted site with a canvas, a CMS and a custom domain from $10 a month. If a developer who works in the product's code will, use v0 for Next.js on Vercel, or Lovable if you want the backend generated from a chat. Lovable and v0 produce code projects, and a landing page is one of the things they build. If you have not settled what the page should say, iter0 builds one launch page from a brief.

8 Steps to Design a Website with AI (Without Starting Over Every Week)

Most tutorials on how to design a website with AI jump straight to prompts. That is why teams regenerate homepages until nobody trusts the output. A stable process treats AI as execution inside a brief, not as strategy. Founders, marketers, and solo creators tired of throwing away last week's AI output can follow these eight steps in order: define the page job, approve structure, lock critical copy, insert real proof, test mobile, publish, and iterate one section at a time. Skipping early steps is what forces the weekly restart cycle.
