Lunora is a type-safe, real-time backend framework on Cloudflare Workers and Durable Objects with a Vite-first developer experience. Define a schema and write query, mutation, and action functions on the server; the client gets end-to-end typed data with live subscriptions, optimistic updates, and an offline queue — types sync from server to client automatically via codegen.
Realtime backends, in a few lines of code.
Define a schema, write a function — Lunora gives you a typed, live-syncing API on Cloudflare's edge. No glue code, no infrastructure to manage.

Everything you need to ship realtime
Realtime, storage, types, and a studio — typed and edge-native by default.
Everything is code
Schema, queries, and mutations in pure TypeScript — codegen keeps server and client in lockstep.
export default defineSchema({ todos: defineTable({ text: v.string(), done: v.boolean(), }),});Realtime by default
Queries are subscriptions. Every mutation pushes live updates to all clients — with optimistic writes and an offline queue.
// subscribes once, re-renders on every changeconst todos = useQuery(api.todos.list);const add = useMutation(api.todos.add);Edge-native & sharded
State lives in SQLite-backed Durable Objects at the edge. Shard by key, or go global to replicate reads across regions.
export const messages = defineTable({ roomId: v.string(), body: v.string(),}).shardBy('roomId');Studio included
A local admin UI for schema, data, SQL, logs, and time-travel ships with every app — running against your live edge database.
End-to-end typed
Types flow from server functions to the client via codegen. Rename a field and the client stops compiling.
export type Todo = { _id: Id<'todos'>; text: string; done: boolean;};Rewind your data
Every shard is a SQLite database you can rewind — restore to any moment in the last 30 days, with no extra infrastructure.
Define. Write. Ship.
From a schema to a live, globally-synced backend in three steps.

One framework, every frontend — Lunora ships live adapters for React, Vue, Svelte, Solid, Astro, TanStack, Nuxt, and Analog, powered by a Vite-first dev experience.
Open source, built together
Lunora is open source and built in the open. Star the repo, file an issue, or send a pull request — every contribution keeps it moving.
