[eko](https://fellou.ai/eko) reports 4.9k GitHub stars, 440 forks, and 11 open issues, last pushed Mar 3, 2026. [langchain](https://docs.langchain.com/langchain/) has 142k stars, 24k forks, and 419 open issues, last pushed Jul 11, 2026. Figures are from public GitHub metadata via [eko's repository](https://github.com/FellouAI/eko) and [langchain's repository](https://github.com/langchain-ai/langchain). | | [eko](/tools/fellouai-eko.md) | [langchain](/tools/langchain-ai-langchain.md) | | --- | --- | --- | | Tagline | Eko (Eko Keeps Operating) - Build Production-ready Agentic Workflow with Natural Language - eko.fellou.ai | The agent engineering platform. | | Stars | 4,937 | 141,504 | | Forks | 440 | 23,516 | | Open issues | 11 | 419 | | Language | TypeScript | Python | | Adopt for | - | LangChain is an open-source platform designed specifically for building agents and applications that leverage large language models (LLMs).

However, it might rely on paid services or premium models from external platforms like OpenAI. - **Adopt for:** LangChain is an open-source platform designed specifically for building agents and applications that leverage large language models (LLMs). It provides a standard framework to develop interoperable components and connect - **License detail:** MIT License, allowing free use for both personal and commercial purposes under its stipulated terms. ## Choose when ### Choose eko if… - eko is primarily TypeScript; langchain is Python. - Tags unique to eko: agentic-framework, agentic-workflow, browser-automation, agentic-ai. - Also covers Inference & Serving. ### Choose langchain if… - langchain is primarily Python; eko is TypeScript. - Pricing: LangChain itself is open-source and free to use. However, it might rely on paid services or premium models from external platforms like OpenAI.. - Tags unique to langchain: gemini, deepagents, generative-ai, chatgpt. - * When aiming to build complex AI-powered agents or applications requiring high-level capabilities like planning, subagent interaction, and file system operations. ## When NOT to use eko - Last GitHub push was 130 days ago (slowing maintenance, Mar 3, 2026). Validate activity before betting a new project on eko. - LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. - AI Agents: Don't use an agent loop when a deterministic workflow would do; agents add latency, cost, and non-determinism. - Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic. ## When NOT to use langchain - * When working on smaller, less complex projects where full-scale integration with sophisticated components is not necessary as LangChain's extensive features might introduce unnecessary complexity. - * If you are primarily focused on JavaScript or TypeScript development as the primary focus of LangChain is Python. Although there is a JS/TS equivalent (LangChain.js), it may not offer the same depth - * For projects requiring heavy customization at lower levels, where a more granular control over individual components is required rather than working with an integrated framework. ## Common questions ### What is the difference between eko and langchain? eko: Eko (Eko Keeps Operating) - Build Production-ready Agentic Workflow with Natural Language - eko.fellou.ai. langchain: The agent engineering platform..

Stars measure visibility, not whether either tool fits your constraints. ### Are eko and langchain open source? Yes - both are open-source projects on GitHub (eko: MIT, langchain: MIT). ### Where can I find alternatives to eko or langchain? GraphCanon lists graph-backed alternatives at [eko alternatives](/tools/fellouai-eko/alternatives) and [langchain alternatives](/tools/langchain-ai-langchain/alternatives) ([eko markdown twin](/tools/fellouai-eko/alternatives.md), [langchain markdown twin](/tools/langchain-ai-langchain/alternatives.md)), ranked by typed relationship edges rather than popularity votes. ### Is there a machine-readable version of this comparison? Yes. The markdown twin at [this comparison](/compare/fellouai-eko-vs-langchain-ai-langchain.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, eko or langchain? eko: Slowing. langchain: Very active. Compare maintenance labels, days since push, and release cadence in the trust section below - stars alone do not measure maintenance. ### Where are the full trust reports for eko and langchain? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [eko trust report](/tools/fellouai-eko/trust); [langchain trust report](/tools/langchain-ai-langchain/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=fellouai-eko`](/api/graphcanon/graph?tool=fellouai-eko) - LLM index: [/llms.txt](/llms.txt) - Full corpus: [/llms-full.txt](/llms-full.txt) _GraphCanon - The knowledge graph for AI development. https://www.graphcanon.com/_
