[langchain](https://docs.langchain.com/langchain/) reports 147k GitHub stars, 25k forks, and 541 open issues, last pushed Sep 18, 2026. [SAM](https://github.com/SyntheticAutonomicMind/SAM) has 130 stars, 6 forks, and 0 open issues, last pushed Sep 19, 2026.

SAM: An AI assistant for everyone. See the comparison table for live GitHub stats and shared categories. ### When should I choose langchain over SAM? Choose langchain over SAM when langchain is primarily Python; SAM is Swift; License: langchain is MIT, SAM is GPL-3.0; Tags unique to langchain: agents, ai-agents, framework, langchain; When you need a framework that simplifies chaining together interoperable components and third-party integrations for AI application development. ### When should I choose SAM over langchain? Choose SAM over langchain when SAM is primarily Swift; langchain is Python; License: SAM is GPL-3.0, langchain is MIT; Requirements: Min 4 GB RAM; For optimal use with local AI models, a system with 16GB+ RAM is recommended.; The system should be equipped with macOS 14.0 (Sonoma) or later.; Tags unique to SAM: ai-assistants, apple-silicon; You should use SAM when you are working on a macOS system equipped with Apple Silicon as it is optimized for such hardware. ### When should I avoid langchain? If you prefer a framework that does not offer built-in capabilities for common usage patterns such as planning and subagents, as LangChain's Deep Agents provide these features. When you need a higher-level abstraction that does not require detailed agent orchestration, as LangChain's LangGraph is designed for low-level control over agent workflows. ### When should I avoid SAM? Avoid using SAM if you are developing on an Intel-based Mac or any system running a different operating system as it is specifically designed for macOS and Apple Silicon. Do not opt for SAM if your project requires low memory consumption, because supporting local AI models typically demands high RAM (16GB+) and significant disk space. ### Is langchain or SAM more popular on GitHub? langchain has more GitHub stars (146,576 vs 130). Stars measure visibility, not whether either tool fits your constraints. ### Are langchain and SAM open source? Yes - both are open-source projects on GitHub (langchain: MIT, SAM: GPL-3.0). ### Where can I find alternatives to langchain or SAM? GraphCanon lists graph-backed alternatives at [langchain alternatives](/tools/langchain-ai-langchain/alternatives) and [SAM alternatives](/tools/syntheticautonomicmind-sam/alternatives) ([langchain markdown twin](/tools/langchain-ai-langchain/alternatives.md), [SAM markdown twin](/tools/syntheticautonomicmind-sam/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/langchain-ai-langchain-vs-syntheticautonomicmind-sam.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, langchain or SAM? langchain: Very active. SAM: 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 langchain and SAM? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [langchain trust report](/tools/langchain-ai-langchain/trust); [SAM trust report](/tools/syntheticautonomicmind-sam/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=langchain-ai-langchain`](/api/graphcanon/graph?tool=langchain-ai-langchain) - 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/_
