What CopilotKit does

CopilotKit (legal entity: Tawkit, Inc.) is a Seattle-headquartered, Israel-engineered developer-tools and infrastructure company founded in 2023 by brothers Atai Barkai and Uli Barkai. It provides an open-source, MIT-licensed frontend framework (CopilotKit SDKs for React, Angular, Vue, Svelte, iOS, Android, React Native, Flutter) together with the AG-UI (Agent-User Interaction) Protocol — a bi-directional HTTP + Server-Sent Events protocol standardizing how AI agents communicate with user-facing applications through typed JSON events, shared state, tool calls, and human-in-the-loop checkpoints. The protocol is now adopted as an open industry standard by Google (ADK, A2UI), Microsoft (Agent Framework), Amazon (AWS Strands, AgentCore, Bedrock), and Oracle (Open Agent Specification), and is integrated with 13+ agent frameworks including LangChain, LangGraph, CrewAI, Mastra, Pydantic AI, Agno, LlamaIndex, AG2, and the Claude and OpenAI Agent SDKs.

The company monetizes through a tiered subscription plus enterprise sales motion. The free Developer tier seeds adoption via the `npx copilotkit@latest create` command; the Pro tier at $39/developer/month (up to 5 seats) and Team tier at $500/month (5 seats, self-hosting, with $2,500/month add-on for VPC/On-Prem) target growing teams, while Enterprise contracts deliver unlimited threads, SOC 2 Type II-compliant self-hosted or CopilotKit Cloud deployment, dedicated engineering support, SLA, and self-improving agents via the newly launched Enterprise Intelligence Platform. Customers include DocuSign, Cisco, S&P Global, Deutsche Telekom, Evergreen Wealth, Function Health, plus a publicly cited "majority of the Fortune 500 and Global 50" logo wall (Apple, Walmart, Disney, Bank of America, Tesla, Ford, Toyota, etc.). The platform reports 4+ million weekly downloads of its open-source libraries and millions of weekly production agent-user interactions, with ~25 employees and $27 million in total funding as of the May 2026 Series A led by Glilot Capital, NFX, and SignalFire.

Beyond the core protocol, CopilotKit is extending into adjacent surfaces: AIMock (testing), Pathfinder (knowledge retrieval), Vibe Coding Server with CopilotKit Expert MCP (developer tooling), early-access Slack and Microsoft Teams conversational surfaces, runtime governance via OpenBox AI for EU AI Act compliance, and an internal "skills" system encoding agent conventions. The strategic posture is classic open-core platform expansion — commoditize the protocol to maximize ecosystem breadth, then monetize the managed infrastructure, governance, and intelligence layer sitting on top.

Core offering

CopilotKit provides an open-source framework and enterprise platform for building AI agent-powered applications with real-time human collaboration. Its offerings consist of the AG-UI open protocol for agent-user interaction, Frontend SDKs (React, Angular, and mobile) for embedding copilots and Generative UI, and the Enterprise Intelligence Platform providing persistent threads, analytics, self-improving agents via reinforcement learning, and self-hosted or managed-cloud deployment. Pricing spans a free Developer tier, Pro ($39/developer/month), Team ($500/month), and custom Enterprise contracts.

Product overview

CopilotKit is the Enterprise Agentic Frontend Stack - a platform for building AI agent-powered applications with real-time human collaboration. The portfolio consists of three core layers: (1) CopilotKit Frontend SDKs - open-source React and Angular SDKs for building agent-native applications with Generative UI, shared state synchronization, human-in-the-loop workflows, and MCP Apps support; (2) AG-UI Protocol - the open bi-directional agent-user interaction protocol adopted by Google, Microsoft, Amazon, and Oracle that standardizes communication between agentic backends and user-facing applications; and (3) Enterprise Intelligence Platform - a managed/self-hosted layer providing persistent threads, analytics, self-improving agents through reinforcement learning, and A/B testing capabilities. Additional offerings include AIMock for testing agentic stacks, Vibe Coding Server for improved developer tooling, and integrations with collaboration platforms (Slack, Microsoft Teams) and 13+ agent frameworks (LangChain, Google ADK, Microsoft Agent Framework, AWS Strands, Mastra, Pydantic AI, CrewAI, Agno, LlamaIndex, AG2). The platform is deployed via CopilotKit Cloud (fully managed) or self-hosted options.

Direct peers

• LlamaIndex: LlamaIndex provides an open-source data and agent framework for LLM applications with first-party CopilotKit integration via AG-UI. Overlap is high in the agent-building layer and the two compete to be the default stack for production agentic apps.
• Mastra: Mastra is a TypeScript-native AI agent framework with native AG-UI integration via CopilotKit. Comparable developer audience and competing on the agent-runtime + frontend bundling for production applications.
• Pydantic AI: Pydantic AI offers a type-safe Python agent framework with native AG-UI support built by Rocket Science in collaboration with the Pydantic team. Direct overlap on agent framework targeting Python developers building production agents.
• CrewAI: CrewAI is a multi-agent orchestration framework that ships first-party AG-UI integration through CopilotKit React components. They overlap on multi-agent runtime and share the same enterprise buyer building agentic applications.
• Agno: Agno (formerly phidata) is an agent framework with first-party AG-UI integration enabling structured streaming, live user inputs and human-in-the-loop. Comparable open-source agent runtime targeting similar enterprise and developer customers.
• LangChain: LangChain (LangGraph) is a closely comparable agent framework with open-source SDKs and an enterprise platform (LangSmith). CopilotKit integrates with LangGraph via AG-UI, but both compete for the same developer mindshare and enterprise budget when teams build agentic applications.
• AG2: AG2 (formerly AutoGen) is a multi-agent orchestration framework with official CopilotKit integration. They overlap directly on multi-agent runtime and compete for the same enterprise agent-native application builds.
