It provides a unified interface for running agents in both **computer and browser environments**. ## Framework Comparison | Feature | Eko | Langchain | Browser-use | Dify.ai | Coze | |--------------------------------------|-------|------------|--------------|----------|--------| | **Supported Platform** | **All platform** | Server side | Browser | Web | Web | | **One sentence to multi-step workflow** | ✅ | ❌ | ✅ | ❌ | ❌ | | **Intervenability** | ✅ | ✅ | ❌ | ❌ | ❌ | | **Development Efficiency** | **High** | Low | Middle | Middle | Low | | **Task Complexity** | **High** | High | Low | Middle | Middle | Middle | | **Open-source** | ✅ | ✅ | ✅ | ✅ | ❌ | | **Access to private web resources** | ✅ | ❌ | ❌ | ❌ | ❌ | ## Features - [x] Pure JavaScript: Built for browsers and Node.js.🚀 - [x] Multi-Agent: Unleash power with multiple Agents in one task.📈 - [x] Agent/Tool Flexibility: Customize new Agents and Tools in just one line.🎉 - [x] Native MCP: Connects seamlessly with [Awesome MCP Servers](https://mcpservers.org/).🔗 - [x] Dynamic LLM: Balance speed and performance with flexible model choices.⚙️ - [x] Human-in-the-loop: Intervene when it matters most.🤝 - [x] Stream Planning: Dynamic rendering made easy.🎨 - [x] Loop & Listener Tasks: Automate any repetitive task.🤖 - [ ] Observable Chain: *Coming soon* - [ ] Native A2A: *Coming soon* ## Quickstart > **Note**: Please refer to the [Eko Quickstart guide](https://eko.fellou.ai/docs/getting-started/quickstart/) guide for full instructions on how to run it. > **Security Warning** > > DO NOT use API Keys in browser/frontend code! > > This will expose your credentials and may lead to unauthorized usage. > > Best Practices: Configure backend API proxy request through baseURL and request headers. > > Please refer to the link: https://eko.fellou.ai/docs/getting-started/configuration#web-environment ```typescript const llms: LLMs = { default: { provider: "anthropic", model: "claude-sonnet-4-20250514", apiKey: "your-api-key" }, openai: { provider: "openai", model: "gpt-4.1", apiKey: "your-api-key" } }; let agents: Agent[] = [new BrowserAgent(), new FileAgent()]; let eko = new Eko({ llms, agents }); let result = await eko.run("Search for the latest news about Musk, summarize and save to the desktop as Musk.md"); ``` ```bash $ pnpm install @eko-ai/eko ``` ## Use Cases - Browser automation and web scraping - System file and process management - Workflow automation - Data processing and organization - GUI automation - Multi-step task orchestration ## Documentation Visit our [documentation site](https://eko.fellou.ai/docs) for: - Getting started guide - API reference - Usage examples - Best practices - Configuration options ## Development Environments Eko can be used in multiple environments: - Browser Extension - Web Applications - Node.js Applications ## Community and Support - Report issues on [GitHub Issues](https://github.com/FellouAI/eko/issues) - Join our [slack community discussions](https://join.slack.com/t/eko-ai/shared_invite/zt-2xhvkudv9-nHvD1g8Smp227sM51x_Meg) - Join our [Discard](https://discord.gg/XpFfk2e5):  - Contribute tools and improvements - Share your use cases and feedback [](https://star-history.com/#FellouAI/eko&Date) ## License Eko is released under the MIT License.
