LangChain just open-sourced Claude Code’s architecture.

MIT licensed. Any model. $0.

It’s called Deep Agents, built on LangGraph, ships with everything a coding agent needs

Here’s what’s inside:

• Planning first
• Filesystem access
• Subagent delegation
• Human-in-the-loop built in
• Long-term memory

The whole thing is built on LangGraph so you get streaming, Studio, and checkpointing out of the box

One line to start: → pip install deepagents → create_deep_agent(tools=[your_tool], system_prompt=”…”)

This is what production-grade agentic AI looks like when it’s open source.
