Offline Protocol

Offline Protocol is an SDK and platform for devices, apps and machines that coordinate directly with each other: phones, handhelds, gateways and site computers exchange messages, shared documents and service calls over Bluetooth LE, local Wi-Fi and a mesh of nearby devices, with a hosted relay when no local path exists. Teams use it to cut cloud round trips and custom integration work, and to keep field work moving when the uplink is slow or down.

This plugin gives ChatGPT and Codex read-only access to the public Offline Protocol developer registry. Ask which packages fit your app and it looks up SDK packages with their versions, platforms and licenses, product workflows with reference architectures, and integration guides for each area. It resolves the exact install for React Native, React web, Python (PyPI) and Rust (crates.io), explains Bluetooth and local-network permissions, turns an app idea into an architecture plan with a starter template, and previews the files a scaffold would contain.

New in SDK 0.29: the Python service on a Linux or Mac box starts every transport it is configured for, and its HTTP front lets programs that do not use the SDK call a service on another device with an ordinary HTTP request, carried end to end encrypted. Ask the plugin how to run one service per box or how to call a service on another machine, and it answers from the integration guide.

It is for developers building or evaluating apps and systems whose devices must coordinate on site.

Limitations: the plugin is read-only and needs no account. It does not create or edit project files; to create a project or add packages, run the Offline Protocol CLI on your computer (offline create, offline init). It does not read your apps' data, and it does not discover, connect to or control physical devices. Starter templates cover React Native and React web. Native Swift and Android packages are early previews (the Android library is a GitHub release download, not on Maven Central), and the firmware leaf crate compiles for microcontrollers but has not run on a board; the plugin says so rather than presenting them as finished or substituting another framework. There is no Flutter package.

Licenses: the Mesh SDK (React Native, Python, Rust) is AGPL-3.0-only, with a commercial license available from Offline Protocol, Inc. The OfflineID SDKs and Proof of Location (beta) are MIT. Shared types and identicons are ISC.
