Uma tela de cadastro, duas execuções: Claude Code com e sem a EpicPxls
Demos ao Claude Code a mesma tarefa duas vezes, uma sozinho e outra com o MCP da EpicPxls. Aqui está tudo o que ele fez, com capturas reais e o HTML que escreveu.
Os prompts
Os dois começam com a mesma frase. A segunda execução adiciona o MCP e pede 4 versões. Nenhuma tinha plugins, hooks ou CLAUDE.md.
Design a sign-up screen for a fitness app. Write it as one self-contained HTML file named signup.html.Design a sign-up screen for a fitness app. Use the EpicPxls MCP: find 4 different fitness app UI kits, look at their real screens, then build 4 versions as signup-1.html to signup-4.html, each one following a different kit's layout, spacing and type scale. Each file is one self-contained HTML file. At the end, list which kit each version is based on.Execução 1: só o Claude Code
Ele escreveu um arquivo em 88 segundos sem olhar nenhuma referência.
signup.html
I made signup.html, a sign-up screen for a made-up fitness brand called Kinetic. It's one file with no external dependencies. I haven't opened it in a browser, so check how it looks and behaves before relying on it.Abrir ao vivo

A config limpa pede aprovação antes de comandos de shell, então os dois downloads com curl foram bloqueados. O agente mudou para o WebFetch, que salvou as imagens no disco, e as abriu com Read.

Palavra por palavra, como ele terminou a execução.
I've built four sign-up screens for a fitness app, signup-1.html to signup-4.html. Each is one HTML file with no external dependencies. I haven't opened them in a browser, so the layouts haven't been checked visually.
I found the kits with the EpicPxls search and looked at their real screens. Each file follows one kit's layout, spacing and type scale, and uses its own text and inline SVG icons (none of the kits' sample copy, logos or photos). The source kit is also noted in a comment at the top of each file.

All four check the fields before submitting, let you show or hide the password, and show a success state.
EpicPxls didn't provide a sign-up screen for Fitnex or GymTracker, so versions 3 and 4 are built from those kits' other screens. Fitzy and Sketchwire had real sign-up and login screens to follow.
The kits are paid items, so the EpicPxls terms ask you to credit the item URL if you ship something built from one.
