What RēDesign is built for
RēDesign is made by the team that publishes this site. It sends one UI screenshot to several AI models at the same time and shows the HTML redesigns they return in a gallery next to the original [3]. In one run you can ask each model for a different number of variants [3]. It comes with prompt presets such as faithful refresh, bold reimagine and minimalist, and you can also write your own prompts [3].
It shows two outputs with the model names hidden, and each pick you make updates a ranking of the models [3]. With one click it checks an output's text contrast against WCAG AA, using the rendered pixels [3]. It locates and crops logos, product photos, avatars and illustrations so redesigns can embed the real brand marks [3]. You can download a whole run as a zip, or download a DESIGN.md file for the redesign you picked so a coding agent can rebuild that look [3].

Builder.io's Pro plan costs $24 per user per month [4]. Its Team plan costs $40 per user per month [4]. The Pro and Team plans include one seat [4]. Additional Agent credits are sold in increments of 500 monthly AI credits for $25 per month [4]. Builder.io defines an Agent credit as its unified usage metric for generative AI operations across the Builder platform [4].

RēDesign runs as a packaged app on Windows, downloaded from GitHub Releases as redesign-windows-x64.exe [3]. The packaged app is for Windows only; running from source works on Windows, macOS or Linux with Bun 1.2 or newer [3]. In daily use, you paste your API keys and it works out which provider each key belongs to, rotating through several keys per provider and pausing keys that keep failing [3]. You can line up several batches, start them together and drag waiting batches to change their order [3]. Everything in the app can also be done from the command line, and an AI agent can control it too [3].
