What is 3dinterior?

3dinterior is a free Astro v7 theme designed for architects and design studios to showcase their work. It takes project images, descriptions, and contact details as content inputs and produces a static, mobile-responsive portfolio website. The theme is built with Tailwind CSS v4 and distributed under the MIT License by Nearmelab, with all demo images sourced from Pexels.

Key Features

• 100/100 Lighthouse score — The theme is optimized for performance, scoring a perfect 100 on all Lighthouse categories out of the box.
• Portfolio-first design — A minimalist layout focused on presenting projects and design work, with a clean gallery-style presentation.
• Mobile-responsive — The layout adapts to different screen sizes, targeting desktop, tablet, and mobile visitors.
• Zero JavaScript (optional) — The theme can run without any client-side JavaScript, making it fast by default; you can add interactivity only where needed.

Who is it for?
