CopilotKit (feat. CoAgents)

In plain words

CopilotKit is an open-source framework that enables developers to build AI copilots and agents directly into React applications. It provides frontend infrastructure for LangGraph AI agents, allowing full-stack and React engineers to integrate AI functionality without specialized AI expertise. The framework includes CoAgents, which streamlines the process of connecting agent logic to user interfaces. Built for developers, it simplifies AI implementation in modern web applications.

CopilotKit is the open-source framework (12k+ GitHub stars) for building AI Copilots & AI Agents into React apps. Every React/Full-Stack engineer is now an AI engineer. Today, we're launching 🪁CoAgents🪁 - frontend infrastructure for LangGraph AI agents 🚀

The Enterprise-Ready Frontend Stack for Agents. CopilotKit lets you integrate LLMs or agents with real-time context, UI control, and full flexibility.

AG-UI (Agent–User Interaction) is the general-purpose, bi-directional connection between a user-facing application and any agentic backend. The Enterprise Agentic Frontend Stack. Build rich agentic applications that learn from every interaction. Self-hostable and built to scale with your org. Start from a real agent experience, then make every interaction look and feel like your product. Connect the sources your company already trusts. Give every employee one agent that can answer with citations, analyze across systems, and prepare the next action. Which enterprise customers mentioned pricing this quarter? Summarize by segment. Your agent acts inside the product, learns from real use, keeps…from copilotkit.ai

  CopilotKit – a hackable OSS copilot for any react app2023 · github.com · ▲10

  CopilotKit is a typescript library for adding a hackable copilot to any react app. You can let the copilot interact with your app via plain typescript closures, and give it (explicit) read access to app data. An example user interaction could look like: - "Which of these travel destinations has a rich architecture history?" - [Copilot answers] - "Great. Add these to my august trip folder, except the ones where it's typically rainy then" - [Added] Recursive agent integration (via Langchain) is in the works - if you have ideas I'd love to hear them here or on the discord.

  Lovable▲1,477

  Hey HN! Previous CERN physicist turned hacker here. We've developed a way to make AI coding actually work by systematically identifying and fixing places where LLMs typically fail in full-stack development. Today we're launching as Lovable (previously gptengineer.app) since it's such a big change. The problem? AI writing code typically make small mistakes and then get stuck. Those who tried know the frustration. We fixed most of this by mapping out where LLMs fail in full-stack dev and engineering around those pitfalls with prompt chains. Thanks to this, in all comparisons I found with: v0,…

  I wasn't quite sure if this qualified as "Show HN" given you can't really download it and try it out. However, dang said[0]: > If it's hardware or something that's not so easy to try out over the internet, find a different way to show how it actually works—a video, for example, or a detailed post with photos. Hopefully I did that? Additionally, I've put code and a detailed guide for the netboot computer management setup on GitHub: https://github.com/kentonv/lanparty Anyway, if this shouldn't have been Show HN, I apologize!
