Inside the Sim website design
Sim is an AI website built with custom code and Next.js. Its pages are built from testimonials, features, footer, hero, stats, product demo, certification, and CTA sections, shown here in full-page captures and a scroll recording. Typography: Season (display text, headings, and body text). Colours: background #FFFFFF, text #1A1A1A, main buttons #000000, surface #F7F7F7.
Sim is the open-source AI workspace where companies build, distribute, and govern AI agents. 270+ integrations, every major LLM, permission groups, spend limits, and self-hosting. Its visual style is minimal, corporate, and typographic, with announcement bar, navigation bar, and hero among its components.
Why we picked it
A tight grayscale palette and heavy black headline type let a dense workflow screenshot, full of chat panels and node diagrams, stay the visual focus without competing colour. Large customer photography and three bold stat numbers break up the technical panels, pacing the long page so it reads as proof, not just feature lists.
What to look for
- Testimonials: names, roles, and photos or logos for credibility
- Features: benefits framed around what the user gets, not internal capability names
- Footer: grouped navigation with clear column headings
- Hero: a specific headline instead of a generic slogan
