Languages & SDKs

xNet is a protocol first and an app second. The same signed, hash-chained, last-write-wins data model can be implemented — and proven byte-for-byte — in more than one language, and the JavaScript runtime binds to more than one UI framework. This page is the honest map of what exists today and how mature it is.

You don't have to trust us — you can check

Every implementation below passes the same golden vectors: identity (did:key), the canonical-JSON BLAKE3 change hash, signing, and LWW convergence. That shared corpus is the difference between “supported” and “verifiably interoperable.”

The two axes

There are two different “multi-X” stories, and they mean different things:

• Languages implement the protocol (identity, change hashing, replication, authorization) and interoperate over the wire.
• JavaScript UI frameworks bind the same JS runtime (createXNetClient + liveQuery) into React, Vue, Svelte, or Solid.

Maturity matrix

What the badges mean: Reference the canonical implementation the vectors are generated from · Stable SDK first-class and app-ready · Beta real and conformance-pinned, still evolving · On demand a thin binding published when asked for · Reference kernel a verifier / teaching implementation.

Languages

Language	What you get	Maturity	Where
TypeScript	The full runtime + React SDK, published to npm	Reference	Quickstart
Swift	Native SDK — schemas, store, query, SwiftUI live binding, SQLite	Native SDK · beta	Swift
Rust	Portable interop kernel + C/UniFFI binding surface	Core · beta	Rust
Python	~100-line reference kernel + vector verifier	Reference kernel	Implement it
Any language	Build a conforming impl from the spec + vectors	DIY	Implement it

JavaScript UI frameworks

Framework	What you get	Maturity	Where
React	Hooks and components — the toolkit the app itself uses	Stable SDK	React hooks
Vue	useQuery / useMutate data binding (no components)	Adapter · on demand	Frameworks
Svelte	liveQuery is already a Svelte store	Adapter · on demand	Frameworks
Solid	createQuery via from()	Adapter · on demand	Frameworks
Vanilla / Lit / Angular	Subscribe to liveQuery directly	Pattern	Frameworks

Honest scope

Only React ships UI components; the component kit is React by design (see the framework support policy). The Swift and Rust packages live in the repo (SwiftPM / Cargo), not on a public registry yet — the per-language pages show how to depend on them today.

Pick your path

JavaScript frameworks → React, Vue, Svelte, Solid, or vanilla — bind the runtime in ~40 lines.

Swift — XNetKit → Define schemas in Swift and bind queries into a SwiftUI re-render loop.

Rust — xnet-core → The portable interop kernel that backs native SDKs, with C/UniFFI bindings.

Implement it in any language → The kernel, the golden vectors, and how to claim conformance.
