One Config File

export default {
theme: "arcade",
database: true,
auth: {
providers: ["google", "magic-link"]
},
payments: {
provider: "stripe",
mode: "subscription"
},
email: {
provider: "resend"
},
features: {
blog: true,
ecommerce: false,
chat: true
}
}
Themes for Every Playstyle
Each theme is a complete design system. Switch with one config change.
Vibrant gradients, aurora effects, and playful energy. Perfect for consumer-facing apps and creative brands.
Raw, terminal-inspired aesthetics with monospace typography. For developers who ship fast and break conventions.
Clean Swiss-style design with generous whitespace. When your product needs to speak for itself.
