- **License detail:** hello-agents is covered under an unconventional license which may require further review before usage.

## Choose when

### Choose langchain-visualizer if…

- License: langchain-visualizer is MIT, hello-agents is Other.
- Tags unique to langchain-visualizer: python, langchain.
- Also covers Vector Databases.

### Choose hello-agents if…

- License: hello-agents is Other, langchain-visualizer is MIT.
- Requirements: Min 4 GB RAM; Python knowledge assumed.
- Tags unique to hello-agents: llm, rag, tutorial, agent.
- You should use hello-agents if you are interested in practical, step-by-step instructions on building intelligent agents from the ground up.

## When NOT to use langchain-visualizer

- Last GitHub push was 858 days ago (dormant maintenance, Mar 6, 2024). Validate activity before betting a new project on langchain-visualizer.
- 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.
- Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.

## When NOT to use hello-agents

- Avoid using hello-agents if you are looking for a quick, superficial introduction to AI agents; this tool focuses heavily on in-depth learning and practical application.
- Do not opt for hello-agents if you want a more general AI development resource; unlike some competitors, it has a narrower focus specifically on agent creation with advanced methods like LLMs and RAG.
