This lane is the living comparison layer for tools, products, frameworks, and
infrastructure across the agent market.

## What belongs here

* Model ecosystems
* Framework comparisons
* Agent platforms and hosted builders
* Agent infrastructure
* Evaluation tooling
* Browser and computer-use stacks
* Coding agent tools

## Editorial intent

Organize this lane by topic first, not by region or vendor. Each comparison
page should include global coverage, Chinese ecosystem coverage, open-source
options, hosted options, and clear guidance on who should care.

## Current pages

* [Model Ecosystem Map](/ecosystem/model-ecosystem-map): a beginner map of
  model providers, model categories, access patterns, and selection tradeoffs.
* [Agent Frameworks](/ecosystem/agent-frameworks): a topic-first comparison of
  conversation-oriented, graph-oriented, and engineering-first frameworks.
* [Framework Comparison](/ecosystem/framework-comparison): a beginner-friendly
  guide to choosing between LangChain, LlamaIndex, and no framework at all.
* [Agent Platforms And Low-Code Builders](/ecosystem/agent-platforms-and-low-code-builders):
  when to choose builder-first, platform-first, or automation-first surfaces.
* [AI Builder Tools Directory](/ecosystem/ai-builder-tools-directory): a
  beginner directory for choosing assistant, automation, app-builder, and
  template tools by outcome.

## Example starters

* [LangGraph Starter](/ecosystem/examples/langgraph-starter): a minimal graph
  example that future framework comparisons can share.
