The Agent-Native Stack — FAQ
What is Agent-Native Stack?
Every tool an agent can sign up for on its own. It pairs LangGraph, OpenRouter, Mem0, Exa, Pinecone, Langfuse — one tool per job. Autonomous agents that provision their own keys — no human in the signup loop.
Can I change the tools?
Yes — open this stack in the builder and swap any pick, filter by open-source / hosted-API / agent-self-signup, then copy or share the result. Nothing is locked in.
Is it free to use this stack?
The stack, this page, and the builder are free. Each tool has its own pricing, shown on its detail page.
Can an AI agent use this stack?
Yes — it's machine-readable at /api/stack.json?pref=agent, so an agent can request these exact picks (with signup URLs and MCP flags) and act on them.
