OSMO
The developer-first platform for scaling complex Physical AI workloads
OSMO is a developer-first orchestration platform designed to scale complex physical AI workflows across heterogeneous computing environments, including cloud GPUs, simulation clusters, and edge devices. It was originally built internally at NVIDIA to support robotics and embodied AI systems, where workflows span multiple stages such as data generation, training, simulation, and hardware testing. The platform addresses what NVIDIA refers to as the “three computer problem” by unifying these stages into a single pipeline defined through simple YAML configurations. It enables users to orchestrate tasks across Kubernetes clusters, automatically managing dependencies, scheduling, and resource allocation without requiring deep infrastructure expertise. -

A curated catalogue provides prebuilt examples from retail, e-commerce, healthcare, finance, manufacturing, education, and other domains. The visual designer lets users create entity types, typed properties, relationships, and cardinalities while viewing changes immediately. RDF/XML and OWL files can be imported, edited, validated, and exported in formats compatible with Microsoft Fabric IQ. An embeddable JavaScript viewer adds interactive ontology diagrams to other websites. The project is fully static with no backend dependency and also includes structured lessons, hands-on learning paths, undo and redo, JSON export, and GitHub-based catalogue contributions. -

OpenAI Realtime Agents
This is a simple demonstration of more advanced, agentic patterns
This repository demonstrates how to build low-latency, streaming “voice + chat” agents using OpenAI’s Realtime API combined with the OpenAI Agents SDK. The demo shows patterns for connecting a realtime voice stream (audio in/out) with agents that can use tools, maintain state, and orchestrate multi-agent workflows. The SDK offers abstractions such as agent orchestration, event handling, handoffs, state management, and guardrails, tailored to support realtime, conversational systems. The demo includes a Next.js frontend for browser interaction and likely a backend component to orchestrate realtime sessions and agent logic. It also supports a “Chat-Supervisor” pattern where a lightweight realtime chat agent handles user interactions and delegates more complex reasoning or tool usage to a stronger textual model (e.g. GPT-4). Because realtime agents are still a beta feature, the code and API surface are subject to changes and may evolve. -

OpenAPI-to-GraphQL
Translate APIs described by OpenAPI Specifications (OAS) into GraphQL
Translate APIs described by OpenAPI Specifications (OAS) into GraphQL. The Command Line Interface (CLI) provides a convenient way to start a GraphQL server wrapping an API for a given OpenAPI Specification. Use OpenAPI-to-GraphQL as a library in your application to generate GraphQL schemas. The GraphQL interface is created around the data definitions in the given OAS, not around the endpoints, leading to a natural use of GraphQL. Nested data Links defined in the OAS are used to create nested data structures, allowing for (deeply) nested queries. Automatic query resolution Automatically generated resolvers translate (nested) GraphQL queries to API requests. Request results are translated back to GraphQL responses. Mutations Non-safe, non-idempotent API operations (e.g., POST, PUT, DELETE) are translated to GraphQL mutations. Input payload is type-checked. GraphQL subscriptions allow clients to receive a stream of events, such as updates whenever data changes on the GraphQL server. -

OpenClaw CN
The Chinese version of OpenClaw
OpenClaw-CN is a Chinese language community adaptation and localization of the OpenClaw project, focused on making a powerful open-source agent framework usable and understandable for Chinese-speaking developers. It includes translated documentation, localized examples, and language-specific nuances so that developers in the Chinese ecosystem can adopt and contribute without a language barrier. The repository mirrors the structure of the upstream project but adds Chinese translations of core workflows, prompts, guidelines, and best practices for building multi-agent systems or AI applications. Beyond simple translation, the project often curates region-specific integrations or tooling recommendations that resonate with local developer environments and platforms. It helps accelerate adoption by providing readable guides, sample configurations, and annotated code that aligns with Chinese developer preferences and tooling conventions. -

PocketMocker
In-page HTTP controller for frontend development
PocketMocker is an in-page HTTP controller and mocking tool for frontend developers that lets you intercept, modify, or simulate API responses directly in a web application without requiring backend changes or separate mock servers. Running inside the browser, it provides a floating control panel that automatically captures outgoing requests and allows developers to override responses, simulate errors or latency, or test edge cases on the fly. This makes building, debugging, and verifying user interfaces significantly faster because developers can instantly see how their UI reacts to different API conditions without switching contexts. Pocket-Mocker also supports team collaboration through configuration plugins and shared rule sets. Its UI and manual are designed to be intuitive, so even those new to API mocking can quickly catch up. For complex applications with many third-party endpoints or unpredictable backends, Pocket-Mocker removes friction in development and testing cycles. -

PostGraphile
Execute a command and get an instant high-performance GraphQL API
GraphQL is a new way of communicating with your server. It eliminates the problems of over- and under-fetching, incorporates strong data types, has built-in introspection, documentation and deprecation capabilities, and is implemented in many programming languages. This all leads to gloriously low-latency user experiences, better developer experiences, and much increased productivity. Because of all this, GraphQL is typically used as a replacement for (or companion to) RESTful API services. PostgreSQL is the self-proclaimed “world’s most advanced open source database,” with each new release bring more amazing features and performance gains. Thinking of your database as a plain CRUD store is now an archaic viewpoint as modern PostgreSQL can do so much for you — from authorization with Row-Level Security (RLS, introduced in PG9.5), through Foreign Data Wrappers (FDW), to real-time notifications with LISTEN/NOTIFY. -

Precedent
An opinionated collection of components, hooks, and utilities
Precedent is an opinionated Next.js starter template that packages reusable components, hooks, utilities, and production-minded defaults. It provides a prepared foundation for teams that want to begin building an application without assembling every frontend dependency manually. The template combines Next.js and TypeScript with Tailwind CSS, Radix UI primitives, Framer Motion animations, Lucide icons, and optimized fonts. Clerk integration supplies ready-made user management and authentication components. Included hooks cover intersection observation, local storage, scrolling, and debouncing, while utilities handle common string and number formatting tasks. ESLint and Prettier enforce consistent code quality, and Vercel Analytics can measure traffic with privacy-conscious reporting. Developers can clone it with create-next-app or deploy it directly to Vercel and then replace the example interface with their own product. -

Preswald
Python tool for browser-based interactive data apps in one file
Preswald is an open source Python-based framework and static-site generator designed for building interactive data applications that run entirely in the browser. It packages application logic, data processing, and user interface components into a single self-contained output, enabling easy sharing and deployment without requiring local dependencies. Preswald leverages a WebAssembly runtime along with technologies like Pyodide and DuckDB to execute Python code directly in the browser environment. This approach allows developers to create dashboards, reports, notebooks, and data tools that are portable, fast, and capable of running offline. Preswald emphasizes a code-first workflow where users define applications entirely in Python while using built-in UI components such as tables, charts, and forms. It also includes a reactive execution model that only recomputes necessary parts of the app, improving performance and responsiveness.
