QVAC just launched an open-source JavaScript/TypeScript SDK for building AI applications that run entirely on the user's device - no cloud API, no monthly usage costs.
The QVAC SDK is built on QVAC Fabric, the company's cross-platform inference engine. Inference here means running a trained AI model to generate responses locally, as opposed to sending requests to a cloud server. The SDK targets both desktop and mobile platforms and is released under Apache 2.0, meaning developers can use it in commercial projects without licensing fees.
The problem it's addressing is real: building local AI apps today means stitching together different runtimes for each platform. Separate solutions for desktop, iOS, and Android, with platform-specific integration work at every layer. QVAC is betting that a unified JavaScript layer can abstract that away into a single SDK.
The project is new and unproven. The local AI tooling space is also crowded - multiple projects are working on the same cross-platform problem. But for JavaScript developers who want to ship local-first AI without writing C++ or platform-specific native code, a single SDK that handles the cross-platform inference layer is a reasonable place to start.
