NebulaKit
A production-ready SvelteKit template powered by Cloudflare's full stack. Auth, database, theming, command palette, drag-and-drop, and an LLM chat UI — built in and tested from day one.
Free and MIT-licensed. Deploy to Cloudflare in minutes — this site is built on it.
Batteries included
Cloudflare-native from the ground up — not a generic starter with an adapter bolted on
SvelteKit Framework
Blazing fast web applications with SvelteKit's powerful routing, server-side rendering, and reactive components. Zero-config TypeScript support included.

Secure Authentication
Built-in authentication with session management, OAuth providers, and secure password hashing. Ready for email/password, Google, GitHub, and more.
Cloudflare D1 Database
SQLite at the edge with migrations, type-safe queries, and zero cold starts. Scale effortlessly with automatic backups and point-in-time recovery.

Pre-configured for AI integration with Cloudflare Workers AI. Add chat, embeddings, image generation, and LLM capabilities with a few lines of code.
Test-Driven Development
Complete testing setup with Vitest and Playwright. Unit, integration, and E2E tests configured out of the box. TDD workflow with 90%+ coverage targets.
Adaptive Theming
Beautiful light and dark themes with CSS custom properties. System preference detection, smooth transitions, and WCAG AA contrast compliance.
Command Palette
Power-user navigation with keyboard shortcuts (⌘K). Quick access to all features, search, and actions without touching the mouse.
Developer Experience
Hot module replacement, TypeScript, ESLint, Prettier, and Git hooks configured. Build, test, and deploy with confidence using best practices.
GitHub Copilot Ready
Pre-configured with comprehensive Copilot instructions for TDD workflows, architectural patterns, and best practices. Accelerate development with AI-powered assistance.
WebSocket & Real-time
Built-in support for Cloudflare Durable Objects and WebSockets. Build real-time applications like chat, notifications, and live updates with ease.
RESTful API Architecture
Clean API design with SvelteKit endpoints. Type-safe request/response handling, middleware support, and automatic validation for robust backend services.
Skip the plumbing
Every new project starts with the same weeks of setup. This one starts with it finished.
Deploy in minutes
Cloudflare Workers with D1, KV, R2, and Queues pre-configured. No infra setup.
Real auth, not a stub
Email/password plus Google and GitHub SSO, with account linking already handled.
Accessible & themeable
WCAG-AA colors, light and dark, CSS design tokens — and a contrast validator in CI.
Tested by default
A TDD harness with a real coverage gate, not a token test file and good intentions.
Complete, not a skeleton
Command palette, chat UI, and drag-and-drop are working features, not TODOs.
Type-safe end to end
TypeScript throughout, including Cloudflare Workers types for the bindings.
