    OpenAI Agents JS

    OpenAI Agents JS

    A lightweight, powerful framework for multi-agent workflows

    openai-agents-js is the JavaScript/TypeScript version of the OpenAI Agents SDK, designed to give developers a lightweight but powerful framework for building agentic workflows, voice agents, and tool-augmented LLM systems in JS/TS environments. The SDK is provider-agnostic, meaning while it’s deeply compatible with OpenAI’s APIs, you can also adapt it to use other backends or extension layers. At its core, it introduces primitives like Agents, Tools, Guardrails, and Handoffs, letting you define structured multi-agent systems in a modular way. The repo includes examples showing how to build agents that call local functions, chain between agents, validate input/output, stream responses, and interact in real time (e.g. voice agents via WebRTC). It also has tracing and debugging support so you can introspect how agents executed their workflows. Because it aligns closely with the Python Agents SDK, it aims for cross-language parity so that JS/TS devs can adopt similar agent architectures.

    OpenUI

    OpenUI

    The Open Standard for Generative UI

    OpenUI is an open-source framework focused on enabling AI-driven generation and manipulation of user interfaces through natural language and programmatic inputs. The project aims to bridge the gap between design and development by allowing users to describe UI components and layouts in plain language, which are then translated into structured code or interactive components. It leverages modern AI models and frontend technologies to dynamically generate UI elements that can be customized, refined, and extended within development workflows. OpenUI is particularly useful for rapid prototyping, as it allows developers and designers to iterate on interface ideas without manually writing all the underlying code. The framework also supports extensibility, enabling integration with existing design systems and component libraries. By combining AI-assisted generation with developer control, OpenUI provides a hybrid approach to building interfaces that balances automation with customization.

    Opine

    Opine

    Minimalist web framework for Deno ported from ExpressJS

    A minimalist web framework for Deno ported from ExpressJS. Robust routing. Large selection of HTTP helpers including support for downloading/sending files, etags, Content-Disposition, cookies, JSONP etc. Support for static serving of assets. View system supporting template engines. Content negotiation. The quickest way to get started with Opine is to utilize the Opine CLI to generate an application. The Express philosophy is to provide small, robust tooling for HTTP servers, making it a great solution for single page applications, web sites, hybrids, or public HTTP APIs. Opine aimed to achieve these same great goals, focussing on providing equivalent robust tooling and features for Deno uses. Now Deno's Node compatibility layer is maturing sufficiently to support Express out of the box, Opine is operating in maintenance mode.

    Output

    Output

    TypeScript framework for building AI workflows and agents

    Output is an open-source TypeScript framework designed to build, orchestrate, and manage AI workflows and agents within a single unified system. It consolidates multiple aspects of AI development, including prompt management, evaluation, tracing, cost tracking, and orchestration, into a file-based architecture that lives entirely within the codebase. The framework is built specifically to work with AI coding agents, enabling them to read, modify, and execute workflows directly from structured project folders. It eliminates reliance on fragmented SaaS tools by providing all necessary components locally, ensuring better transparency and control over data and processes. Output includes built-in evaluation systems, such as LLM-as-a-judge scoring, and integrates workflow orchestration tools like Temporal to handle retries, parallel execution, and state management. It also supports multiple model providers through a unified API.

    An Analysis Tool for Smart Contracts

    A container with the required dependencies configured can be found here. The image is however outdated. We are working on pushing the latest image to dockerhub for your convenience. If you experience any issues with this image, please try to build a new docker image by pulling this codebase before open an issue. A collection of the utilities that were developed for the paper are in misc_utils. Use them at your own risk - they have mostly been disposable. This is an improved version of the tool used for the paper. Benchmarks are not for direct comparison. To run the benchmarks, it is best to use the docker container as it includes the blockchain snapshot necessary. In the container, run batch_run.py after activating the virtualenv. Results are in results.json once the benchmark completes.

    Pastel

    Pastel

    Next.js-like framework for CLIs made with Ink

    Pastel is a framework for building rich command-line applications using React (via Ink), offering a Next.js-like developer experience for CLIs. Instead of wiring up argument parsers, help output, and subcommands manually, you structure your CLI as a file-based command tree and focus on writing components that render the interface. Pastel parses and validates command options using Zod schemas, giving you typed, declarative option definitions that also power automatic help messages. It wraps up common CLI concerns such as argument parsing, routing to the appropriate command component, validation, and error handling, so you can concentrate on the command’s behavior and UI. Because it builds on Ink, you can create highly interactive terminal UIs using React components, hooks, and state management patterns you already know from the web. Pastel is zero-config for typical use cases, and there is even a create-pastel-app helper for scaffolding new projects quickly.

    Peinture

    Peinture

    A general-purpose AI image generation framework that supports HF

    Peinture is a sleek, dark-themed web application that brings AI-powered image generation to artists, designers, and casual creators through a modern interface built with React, TypeScript, and Tailwind CSS. Instead of tying users to a single service, Peinture integrates multiple backend providers, including Hugging Face, Gitee AI, Model Scope, and others, so you can switch between models or extend support to custom endpoints — giving you flexibility over where and how your images are generated. It not only generates images from prompts but also includes tools to edit those images after creation, with features like selection tools and reference image support that let you refine artwork in place. The interface supports live motion edits that turn static images into short cinematic clips, prompt enhancement for expanding simple ideas into detailed scenes, and a cloud-friendly storage system that syncs work across devices if configured.

    Rakkas

    Rakkas

    Bleeding-edge React framework powered by Vite

    Rakkas is a bleeding-edge full-stack React framework powered by Vite. You can consider it an up-and-coming alternative to Next.js, Remix, or Gatsby. Although many features have been implemented, Rakkas is still under heavy development. It uses experimental and/or beta features of React and Vite. Minor releases will introduce breaking changes until we hit 1.0. As such, it's not yet ready for production use. If you need a stable React framework try Next.js, Remix, or Gatsby. create-rakkas-app project initializer comes with many features, all of which are optional but we strongly recommend enabling TypeScript and the generation of a demo project on your first try because self-documenting type definitions allow for a smoother learning curve and the demo project source code comes with plenty of comments.

    React Native Detour

    React Native Detour

    SDK for handling deferred deep links in React Native

    React Native Detour is an SDK for handling deferred deep links in React Native applications. It helps apps understand where users should land after installation, even when the original link was opened before the app existed on the device. This is useful for onboarding flows, referral campaigns, shared content links, invite systems, and marketing attribution. The SDK is designed to connect React Native apps with Detour credentials and platform-level integration. It gives developers runnable examples so they can test linking behavior in realistic app scenarios. Its main value is reducing friction around deferred linking, so users can move from a link to the correct in-app destination more reliably.

    React Native Gesture Handler

    React Native Gesture Handler

    Declarative API exposing platform native touch and gesture system

    React Native Gesture Handler is a gesture system for building smooth touch interactions in React Native apps. It replaces the limitations of the standard JavaScript responder system with native-driven gesture recognition. This allows gestures to be tracked on the UI thread, making touch behavior more reliable during animations, scrolling, and complex interactions. The library is especially useful for apps that need swipes, pans, taps, long presses, drag gestures, and nested gesture handling. It integrates closely with React Native Reanimated, making it a common foundation for high-performance mobile interfaces. Its main value is helping developers create fluid, deterministic, platform-native gesture experiences without manually fighting React Native’s default touch system.
