Native SDK

Agent-Native is an open-source TypeScript framework for building agentic applications with purpose-built user interfaces. Developers define each capability once as an action; the same action is used as an agent tool and called by the UI, with shared validation, permissions, implementation, data, and application state. Agents work through this shared action layer rather than clicking through the interface. Actions can also be exposed through HTTP, MCP, A2A, and a CLI. The framework includes agent chat, authentication and permissions, reusable skills and memory, scheduled or event-driven automations, multi-agent teams, and PostgreSQL support with PGlite for local development. It is distributed under the MIT license.

React Native is an open-source framework for building native applications with React. JavaScript components, declarative UI, hooks, and Suspense are rendered through native platform UI on Android, iOS, and other platforms, while Fast Refresh applies JavaScript changes without rebuilding the native app. Native Modules allow JavaScript code to call platform code directly, and the framework can be adopted incrementally in existing applications or used with production frameworks such as Expo. React Native is developed by companies and individual core contributors and is distributed under the MIT license.

Electron is an open-source framework for building cross-platform desktop applications with JavaScript, HTML, and CSS. It is built on Node.js and Chromium, provides binaries for macOS, Windows, and Linux, and is used by applications such as Visual Studio Code. The project is MIT-licensed, maintained under the OpenJS Foundation, and distributed via npm.

Domain SDK is an open-source TypeScript library by OpenCore for managing customer-owned custom domains through a single server-side API. It adds hostnames to an existing hosting platform, returns the exact routing, ownership, and certificate DNS records required by customers, tracks provider-authoritative verification and certificate status, and supports safe removal. The SDK normalizes domain lifecycle operations including adding, reading, listing, verifying, and removing domains. It provides idempotent operations, retry-aware errors, sequential polling with timeouts and cancellation, callbacks, provider backoff, and an isolated in-memory testing adapter. Adapters are provided for Vercel, Cloudflare for SaaS, Railway, Render, Netlify, and bunny.net; a subdomain client can scope tenant-chosen labels under a parent domain. It is server-side only and requires Node.js 20+ or Bun. The package is distributed under the MIT license.

The Temporal TypeScript SDK is an open-source framework for authoring workflows and activities in TypeScript or JavaScript against Temporal's distributed orchestration engine. Temporal executes asynchronous, long-running business logic with durable state and recovery across failures, while the SDK provides client packages for starting and interacting with workflows and worker packages for running workflows, activities, and Nexus Operations. Worker-level execution uses Node-specific capabilities including native modules, worker threads, virtual-machine isolation for the workflow sandbox, AsyncLocalStorage, and async hooks. The repository distributes the SDK as version-aligned @temporalio/* packages and officially supports Node.js 20, 22, and 24; alternative server-side JavaScript runtimes may work for some client features but are not officially supported for workers.
