Chrome DevTools MCP
Chrome DevTools for coding agents
chrome-devtools-mcp is an MCP server that connects AI agents to the Chrome DevTools Protocol so they can inspect pages, record traces, read console/network data, and modify the live browser state under user control. It makes a running Chrome instance visible to MCP clients, enabling agents to debug websites end-to-end—launching Chrome, navigating, profiling, and collecting artifacts in a structured way. The repository spells out environment requirements and cautions that exposing a live browser to agents grants powerful access, so sensitive data should be handled carefully. Beyond static inspection, it exposes operational tools like starting a performance trace that an agent can later analyze to propose optimizations. The server is intended to slot into MCP-capable assistants and IDEs, giving them reliable, typed tools and resource endpoints rather than ad-hoc automation. Documentation from the Chrome team explains how the server augments agents with real debugging capabilities. -

Clarity AI
A Perplexity clone
Clarity AI is an AI-powered “search + chat” tool (similar in spirit to a simplified “AI-powered search engine / assistant”) created by Mckay Wrigley — intended to let users ask questions, get answers, and explore information via conversational interface rather than traditional search. The codebase (TypeScript) leverages LLMs / embeddings to process user queries, retrieve relevant data or context, and respond conversationally; this makes it useful as a personal knowledge assistant, research helper, or Q&A front end over arbitrary datasets or web-available info. Because Clarity AI is open-source, developers can adapt the backend or retrieval logic, integrate their own data sources (databases, documents, APIs), and build custom assistants or knowledge bots tailored to their needs. It can serve as a starting platform for building AI-powered internal tools, knowledge bases, or public-facing “smart search” features. -

DeepSeek-Reasonix
DeepSeek-native AI coding agent for your terminal
DeepSeek Reasonix is a DeepSeek-native AI coding agent designed for terminal-based software development. It is built around prefix-cache stability, which helps reduce token costs during long sessions and allows users to leave the agent running across extended workflows. Reasonix includes a coding mode with filesystem and shell tools, a lighter chat mode, one-shot task execution, health checks, session utilities, and project-scoped memory. It supports reviewed SEARCH/REPLACE edits, plan mode, MCP servers, web search, hooks, skills, semantic indexing, transcript replay, event logs, and cost or cache tracking. The project is especially useful for developers who want an open, terminal-first coding agent optimized for DeepSeek’s cache mechanics. It also includes a prerelease desktop client for users who prefer a GUI over the same agent loop. -

Default composer
JavaScript library to set default values for nested objects
A tiny (~500B) JavaScript library that allows you to set default values for nested objects. "default-composer" is a JavaScript library that allows you to set default values for nested objects. The library replaces empty strings/arrays/objects, null, or undefined values in an existing object with the defined default values, which helps simplify programming logic and reduce the amount of code needed to set default values. To use "default-composer", simply import the library and call the defaultComposer() function with the default values object and the original object that you want to set default values for. -

Design OS
The missing design process between your product idea and your codebase
Design OS is an open-source product planning and UI design framework that sits at the intersection of design thinking and generative AI, guiding creators through a repeatable process from product idea to structured design deliverables. It fills what the maintainers describe as the “missing design process” in AI-first development, helping users define product visions, model data, map user flows, and lay out interfaces before a coding agent begins implementation. The tool is poised to produce production-ready UI components and artifacts that any AI coding tool can consume, encouraging a disciplined front-to-backend workflow that avoids disjointed, reactive design prompts. Design OS emphasizes clarity of intent, consistency of design systems, and exporting usable components rather than just static mockups, which aligns better with automated build pipelines and agent-driven development. -

DevExtreme Reactive
Business React components for Bootstrap and Material-UI
We've focused our energy on performance and best practices offered by the React team. Through immutability and pure React components, we apply ‘memoization’ and all built-in React optimizations to achieve outstanding performance. Fully control the Reactive component state and treat it as a pure view component. Effortlessly enable state persistence and time-traveling without side effects. To help you write less code, our components can also manage their state internally. DevExtreme Reactive Components are built of plugins. Add and deploy only those features you require or extend the built-in functionality with your own (or third-party) custom plugins. TypeScript is often the choice for enterprise-scale web applications. Our TypeScript definitions are autogenerated and are always complete and in sync with docs. Each component text element is customizable. As such, web apps powered by DevExtreme Reactive can be easily localized/globalized. -

Dinero.js
Create, calculate, and format money in JavaScript and TypeScript
Dinero.js is a JavaScript and TypeScript library designed to safely represent, calculate, and format monetary values in applications where precision and correctness are critical. It addresses the limitations of native number handling in JavaScript, which can lead to rounding errors and inaccuracies when working with currency. The library provides an immutable data structure for representing money, ensuring that operations such as addition, subtraction, and conversion do not introduce unintended side effects. It also includes utilities for formatting monetary values according to different locales and currencies, making it suitable for internationalized applications. Dinero.js supports complex financial operations such as comparisons, allocations, and conversions, enabling developers to build robust financial systems with confidence. Its functional architecture and modular design make it highly adaptable and efficient, particularly in modern frontend and backend environments. -

Dockge
A fancy, easy-to-use and reactive self-hosted docker compose.yaml
Dockge is a self-hosted, stack-oriented manager for Docker Compose files designed to simplify container management with a modern web interface. Instead of treating each container individually, it focuses on stacks defined by docker-compose.yaml files, allowing users to create, edit, start, stop, restart, and delete entire stacks through a UI rather than via CLI only. The tool preserves the stack files on disk (rather than hiding them inside a database), so users retain full flexibility to inspect and manage via normal Docker commands. It also supports multiple agents across different Docker hosts, enabling one unified UI to control stacks on multiple servers. The interface is reactive and real-time: progress bars show pulling, starting, and updating operations, and a built-in web terminal allows direct interaction. -
