Introducing AgentLantern, an open-source tool for CrewAI

Hi everyone,

I’m building AgentLantern, an open-source devtool for CrewAI projects.

The goal is to make CrewAI-based projects easier to understand, document, analyze, and visualize, especially when the project starts to grow with multiple agents, tasks, tools, and configuration files.

AgentLantern currently provides three main features:

  • Lantern Docs: generates a browsable documentation site from your CrewAI project by statically reading the source code and configuration files. No LLM calls, no API keys.
  • Lantern Lint: checks CrewAI projects before runtime and helps detect design issues such as missing fields, broken references, or configuration problems.
  • Lantern Play: runs the project and opens a pixel-art runtime viewer where you can observe agents working, delegating, calling tools, and producing outputs.

The project is still early, and I’m mainly looking for feedback from CrewAI users: what would be useful, what is missing, and what kind of problems you face when working on real CrewAI projects.

I’d be happy to discuss here if anyone has thoughts, suggestions, or wants to test it on a CrewAI project.
