CopilotKit vs selvedge

CopilotKit: CopilotKit is a React framework for embedding AI copilots, chatbots, and in-app agents directly into web applications. It provides UI components (chat interface, sidebar, textarea) and backend infrastructure for building agentic frontends — where AI can read and modify application state, take actions, and render generative UI. Supports LangChain, LangGraph, CrewAI, and custom agent backends.; selvedge: Selvedge provides long-term memory for AI-coded codebases, capturing the 'why' behind agent-made changes directly from the agent's context. It acts as a local MCP server, logging structured events to a SQLite database, allowing developers to query the reasoning for code modifications years later.

TL;DR

CopilotKit logo
CopilotKitDev Tooling · ★ 38.2k
When to choose:
  • You are building a React, Angular, Vue, or React Native app and need an MIT-licensed frontend layer for in-app AI copilots, generative UI, and human-in-the-loop state sharing.
  • You want to connect your existing LangGraph, CrewAI, or custom agent backend to web apps, Slack, and Microsoft Teams via the AG-UI protocol.
When to skip:
  • You are looking for a backend agent orchestration engine rather than a frontend/UI integration SDK; use CrewAI, Pydantic AI, or LangGraph for the backend.
  • You want a standalone desktop chat client for personal use; use Cherry Studio.
