A starter and reference for building full-stack web applications on Cloudflare Workers

---

epicflare ships a Remix-powered UI, server routing, and OAuth-protected MCP endpoints so you can build both a user-facing app and tooling APIs on the same Worker.

Quick Start

bunx create-epicflare

This will clone the template, install dependencies, run the guided setup, and start the dev server.

See docs/getting-started.md for the full setup paths and expectations.

Tech Stack

Layer	Technology
Runtime	Cloudflare Workers
UI Framework	Remix 3 (alpha)
Package Manager	Bun
Database	Cloudflare D1
Session/OAuth	Cloudflare KV
MCP State	Durable Objects
E2E Testing	Playwright
Bundler	esbuild

How It Works

Request → worker/index.ts
              │
              ├─→ OAuth handlers
              ├─→ MCP endpoints
              ├─→ Static assets (public/)
              └─→ Server router → Remix components

• worker/index.ts is the entrypoint for Cloudflare Workers
• OAuth requests are handled first, then MCP requests, then static assets
• Non-asset requests fall through to the server handler and router
• Client assets are bundled into public/ and served via the ASSETS binding
