- **Python**: [humanbound](/tools/humanbound-humanbound.md) - Python runtime; [langchain](/tools/langchain-ai-langchain.md) - Python runtime

## Decision facts: langchain

- **Pricing:** freemium - LangChain itself is open-source and free to use. 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 humanbound if…

- License: humanbound is Other, langchain is MIT.
- Tags unique to humanbound: adversarial-testing, agentic-ai, ai-red-teaming, ai-safety.
- Also covers Inference & Serving.

### Choose langchain if…

- License: langchain is MIT, humanbound is Other.
- 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: agents, anthropic, chatgpt, deepagents.
- * 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 humanbound

- 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.
- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.

## 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.
